Upon appeal from the Superior Court. AFFIRMED.

Michael W. Modica, Esquire, Wilmington, Delaware, for Appellant Murad Diggs.

Elizabeth R. McFarlan, Esquire, DELAWARE DEPARTMENT OF JUSTICE,
Dover, Delaware, for Appellee State of Delaware.
TRAYNOR, Justice:

Murad Diggs was convicted in the Superior Court of possession of a firearm

by a person prohibited and possession of ammunition by a person prohibited.1 In

this direct appeal, Diggs claims that the Superior Court erred when it denied his

motion to suppress the evidence seized from him—the firearm and ammunition—

following an investigative detention and frisk that was, in Diggs’s view, unsupported

by reasonable suspicion. More specifically, Diggs challenges the court’s conclusion

that the tip upon which the police were acting came from a “citizen informant” and

therefore was presumptively reliable. Diggs also contends that the Superior Court’s

suppression-hearing factual determinations were flawed because the court failed to

draw a “lost and/or missing evidence”2 inference as a result of the police’s failure to

collect and preserve certain evidence.

Although we agree, in part, with Diggs’s criticism of the Superior Court’s

“citizen-informant” analysis, we disagree with his conclusion that his seizure was

not supported by sufficient reasonable suspicion. Likewise, we reject Diggs’s

contention that the Superior Court’s failure to draw an adverse inference against the

1
According to Diggs’s notice of appeal, his appeal encompasses a drug-dealing conviction in a
separate prosecution under a separate indictment. But Diggs’s briefs make no mention of the facts
surrounding his drug-dealing conviction, nor do his legal arguments touch upon that charge. We
therefore assume that the inclusion of that conviction in the notice of appeal was unintentional or,
if it was not, that Diggs has abandoned that aspect of his appeal.

prosecution—an inference that Diggs did not urge the court to draw in the

proceedings below—was plainly erroneous. Hence, we affirm.

I.
A.
On the date of Diggs’s arrest, Corporal Alexander Marino of the Wilmington

Police Department received a call from a “concerned citizen” on his personal cell

phone.3 The caller informed Corporal Marino that a “black male, approximately 30

to 35 years of age . . . wearing a camouflage jacket, had a small handgun on [sic] his

waistband”4 in the 200 block of South Harrison Street in Wilmington.

The caller was not a stranger to Corporal Marino; in fact, Corporal Marino

had known the caller for 11 years during which the caller had provided information

relating to criminal activity approximately five times. Corporal Marino offered that,

on at least some of those prior occasions, the caller’s information was reliable and

led to arrests of different individuals.

On this particular occasion, though, Corporal Marino was not on duty so he

relayed the information to an on-duty officer—Patrolman Raymond Shupe—who

was near the area described by the caller. Because the Wilmington Police

Department does not provide its officers with cell phones, the conversation between

Corporal Marino and Patrolman Shupe was held on the officers’ personal cell

phones. Shupe recalled that he also received a text message from Marino that day,

but Marino testified he “did not text [Shupe] with any information about the

informant.”5 The State did not produce any cell phone data from which it could be

determined if, when, and how Marino communicated with Shupe because Marino

“clean[s] [his] phone out,”6 that is, deletes his messages, every week.

Patrolman Shupe shared the substance of Marino’s message with his partner

and called other officers for back-up. Soon thereafter, Shupe observed a black male

meeting the informant’s description—eventually identified as Murad Diggs—

wearing a camouflage jacket walking in a southerly direction on South Harrison

Street. Diggs, it turns out, was then 36 years old, barely outside the age range

provided by the informant. As Diggs entered a convenience store, known as the

Shop Smart Market, on the corner of Elm and South Harrison Streets, Patrolman

Shupe parked his marked police vehicle and, recognizing that he might be

confronting an armed person, waited for his back-up to arrive. When two back-up

officers arrived, the four police officers—Shupe, his partner, and the two back-up

officers—approached the store. All four were in Wilmington Police Department

uniforms.

 As Patrolman Shupe entered the store, he immediately encountered Diggs,

who was leaving, in the doorway. At that moment, according to Patrolman Shupe,

he intended to engage in a “consensual encounter.”7 During his suppression hearing

testimony, Patrolman Shupe described his approach to Diggs as well as Diggs’s

reaction:

Q. What happened as you were attempting to enter the store and he
attempting to exist the store?
A. I asked if I could speak with him.
Q. What, if anything, did you ask him?
A. I just asked if I could speak with him.
Q. Why did you ask him that?
A. Because I had to get reasonable articulable suspicion that he had
a firearm before I acted on it.
Q. Was your intention to engage in a consensual encounter?
A. That was my intention.
Q. What happened when you asked Mr. Diggs can I speak with you?
A. He had his cell phone in one hand and a cigar in the other hand,
and he threw them on the ground immediately, got into a defensive
stance and started backing away, he looked left and right like he was
going to run or fight.8

The force with which Diggs threw his phone to the ground was “significant,”9

leading Shupe to believe that “he was trying to break it.”10 And his training and

experience in the use of firearms suggested to Shupe that the stance assumed by

Diggs was “a good place to start to draw a firearm.”11 Based on these factors and

Shupe’s belief—prompted by what Corporal Marino had told him—that Diggs

possessed a firearm, Shupe “took a step forward and . . . grabbed a hold of . . .

Diggs’[s] arm[,]”12 for the purpose of “check[ing] for potential weapons.”13 But

Diggs did not cooperate, and a struggle ensued.

In the struggle, Diggs “began pushing and pulling to get away from

[Shupe].”14 Two of the other officers came to Shupe’s aid, eventually taking Diggs

to the floor and placing him in handcuffs. Patrolman Shupe then conducted a pat-

down search of Diggs for weapons and found a loaded handgun in Diggs’s

waistband. After this encounter, Patrolman Shupe asked the person behind the

store’s counter for access to any video recordings that might have been captured by

the store’s security cameras, but that employee didn’t know how to work the

cameras.15

Patrolman Shupe placed Diggs under arrest for carrying a concealed deadly

weapon (“CCDW”) and resisting arrest. Two months later, Diggs was indicted for

those same charges, but also—because of a prior felony conviction—for possession

of a firearm by a person prohibited (“PFBPP”) and possession of ammunition by a

person prohibited (“PABPP”).

B.

Diggs moved the Superior Court to suppress the evidence of the loaded

firearm on the grounds that it was obtained in violation of his rights under the Fourth

and Fourteenth Amendments of the United States Constitution and Article I, Section

6 of the Delaware Constitution. More specifically, Diggs contended that Patrolman

Shupe’s investigatory stop was unlawful because the officer did not have a

reasonable articulable suspicion to justify that intrusion. The State responded that

the totality of the circumstances, which included “the eyewitness’s information,

Officer Shupe’s observations of the Defendant’s suspicious behavior, Officer

Shupe’s training and experience, and the high crime area, when viewed through the

eyes of a reasonable police officer constituted reasonable articulable suspicion that

the Defendant was committing a crime, specifically CCDW.”16 Likewise, the State

argued that Patrolman Shupe’s frisking of Diggs was justified because Shupe

reasonably suspected that Diggs was armed and presently dangerous.

16
Id. at A26–27 (footnote omitted).
7
 C.

At the hearing on Diggs’s motion to suppress, Corporal Marino and Patrolman

Shupe testified for the prosecution and described, respectively, Marino’s receipt and

transmission of the informant’s tip and Shupe’s response to the tip and encounter

with Diggs as outlined above. For his part, Diggs presented four witnesses, two of

whom were in the store during the encounter and two—Diggs’s sister and mother—

who were near, but outside, the store.

On the day of Diggs’s arrest, Guy Bullock was working as a cook in the store’s

kitchen, which is approximately 30 to 45 feet from the store’s front door. At his

boss’s request, Bullock moved toward the front of the store. It was a particularly

hectic day, and Bullock’s boss was concerned with “[p]otential shoplifting[] and the

store being overcrowded.”17 While in the front of the store, Bullock focused on the

“kids” there, interacting with those who presented a shoplifting risk.

Around that time, Bullock saw somebody grab Diggs’s arm and pull him away

as he opened the door to leave the store. At first, Bullock didn’t know, despite

Patrolman Shupe’s uniform, that the person grabbing Diggs’s arm was a police

officer. In fact, he “thought it was getting ready to be a fight, so [he] moved [a] kid

out of the way.”18 As these events unfolded—according to Bullock, “[e]verything

17
Id. at A109.
18
Id. at A114.
8
happened quickly”19—Bullock was “paying attention to the kids and was looking at

the door”20 as Diggs reached for it. Before Diggs’s arm was grabbed, Bullock did

not hear Patrolman Shupe say anything to Diggs nor did he see Diggs throw

anything.

Andrea Price, a neighborhood resident, was also in the store when Diggs

encountered Patrolman Shupe and confirmed that the store was crowded that day.

She was behind Diggs as he opened the door to leave the store. Price “remember[ed]

an officer grabbing [Diggs’s] arm . . . and pulling his arm back. . . . [A]t that point[,]

[Price] turned around and tried to get out of the way.”21 Price added that, after she

saw the officer grab Diggs’s arm, Diggs “put his hands up” and then saw him

“detained on the floor.”22 Price was unable to describe the “three or four” officers

she saw at the store that day because “[e]verything . . . happened so fast.”23

The court next heard from Na’Isha Pantoja, Diggs’s sister, who was outside

the store. Na’Isha confirmed that her brother’s encounter with the police officers

occurred as Diggs was exiting and the officers were entering the store. As she

approached the store with her children, Na’Isha saw a police officer grab Diggs and

9
take him to the ground. After that, according to Na’Isha, the police searched Diggs

20 to 30 times.

When asked whether she heard Diggs say anything to the officer, Na’Isha first

said that she did not know but then offered that Diggs “might have said” he had “his

ID or something” though she wasn’t “too for sure.”24 Na’Isha did not hear the officer

say anything to her brother, nor did she see her brother throw anything.

Na’Isha also noted that she saw a “little light skin boy . . . [in a] fatigue

jacket”25 similar to the jacket Diggs was wearing leaving the store. It is unclear

whether she saw this individual before or after she saw her brother’s encounter with

Patrolman Shupe. Na’Isha estimated that this “boy” was in his mid-20’s; as

mentioned, Diggs was 36 years old at the time.

Finally, in what must have come as a surprise, during cross-examination,

Na’Isha disclosed that she recorded the incident on her cell phone. Again, the record

is unclear when Na’Isha began to record the incident, but, in any event, the defense

did not play the video during the suppression hearing.

Diggs’s final witness at the hearing was his mother, Julia Pantoja. Like

Na’Isha, Julia observed the event from outside the store. The first thing Julia noticed

24

25
Id. at A137.
10
as she saw the police officers approaching the store was “a couple of guys coming

out”26 of the store, one of whom was wearing a camouflaged jacket. Julia agreed

with Na’Isha’s assessment that this other person was “[m]aybe about 25.”27

According to Julia, as her son was leaving the store about the same time as

the officers—she recalled that there were six or seven officers—were trying to enter,

“it looked like it was a tug of war, [and] the officers grabbed [Diggs’s] arm.”28 She

did not hear the officer say anything before he grabbed Diggs’s arm. Like Diggs’s

other witnesses, Julia did not see Diggs throw anything. Lastly, Julia provided a

more conservative estimate of the number of searches conducted by the police during

Diggs’s detention; she recalled that “[t]hey searched [Diggs] about six to seven

times.”29

D.

In the Superior Court, Diggs classified Marino’s informant as an anonymous

informant whose information was too vague to justify Patrolman Shupe’s seizure of

him—a seizure that Diggs claimed occurred immediately, “before any of [his]

26

11
actions after the police arrived [at] the convenience store.”30 And, according to

Diggs, because the informant did not share with Marino the basis of her knowledge

that the person she was reporting was armed, the reliability of her tip was further

undermined.

The State countered that the totality of the circumstances, when viewed

through the eyes of a reasonable police officer, supported Patrolman Shupe’s

suspicion that Diggs was unlawfully carrying a concealed deadly weapon. Those

circumstances included the information provided by the informant,31 Patrolman

Shupe’s training and experience, and the fact that the 200 block of South Harrison

Street is a “high crime area.”32 In responding to Diggs’s attack on the reliability of

the informant’s tip, the State invoked the informant’s status as a “concerned citizen,”

who, under a line of cases including Bailey v. State,33 and Hooks v. State,34 should

be considered presumptively reliable.

The State’s March 22, 2019 Response to Defendant’s Motion to Dismiss describes the informant
as an “eyewitness.” App. to Opening Br. at A26. But Corporal Marino’s suppression-hearing
testimony indicated only that he had “received information from . . . a concerned citizen that an
individual in the area of the 200 block of South Harrison was in possession of a handgun.” Id. at

pointed out in his argument below.

 E.

The resolution of the issues presented to Superior Court depended in large part

on whether Diggs was seized for Fourth Amendment purposes before or after he

threw his phone and cigar down and assumed a defensive stance. It was therefore

necessary for the court to untangle the varying accounts of what happened at the

store’s entrance that day. The Superior Court succinctly resolved “the relevant

inconsistencies”:

The Court understands from all of the testimony that the encounter
between Officer Shupe and Mr. Diggs happened fast over a few
seconds. In addition, given the narrow aisles at the Market, no witness
at the Hearing had a clear view of the face to face interaction between
Officer Shupe and Mr. Diggs other than Officer Shupe. Mr. Bullock
was behind Mr. Diggs and, at the request of management, talking to
some boys in the shop. Ms. Pierce was also behind Mr. Diggs.
Although not dealing with customers like Mr. Bullock, Ms. Pierce is 10
inches shorter than Mr. Diggs and necessarily had her view of the face-
to-face encounter between Officer Shupe and Mr. Diggs blocked by Mr.
Diggs. Na’Isha and Juli[a] Pantoja were outside the Market and were
restricted in their view of the encounter by Officer Shupe and the
additional WPD officers at the scene. Under these circumstances, the
Court would expect the testimony to differ as to what exactly happened
between Officer Shupe and Mr. Diggs.
Officer Shupe was in an area that had recently experienced a
shooting and an incident involving Molotov cocktails. The citizen
informant provided that Mr. Diggs had a concealed firearm. According
to Officer Shupe, Officer Shupe tried to talk to Mr. Diggs but, after
asking to speak with him, Mr. Diggs reacted in a manner that Officer
Shupe had never seen before. Mr. Diggs threw down the items in his
hands, got into a defensive position and took steps backwards. At this
point, Officer Shupe believed that Mr. Diggs had a gun and grabbed

13
 him to check for weapons. A struggle ensued, other WPD officers
joined in and a loaded handgun was found in Mr. Diggs’[s] waistband.35
The Superior Court’s legal analysis proceeded from the premise that the tip

received by Corporal Marino, who passed it along to Patrolman Shupe, was provided

by a “citizen informant” and therefore was presumptively reliable. Given that and

Patrolman Shupe’s observation of an individual matching the informant’s

description in the location identified by the informant, the court found that “Shupe

had a particularized and objective basis to suspect that Mr. Diggs was committing a

crime—possible possession of a firearm without a license or, if hidden, carrying a

concealed deadly weapon.”36 This, according to the court, justified Patrolman

Shupe’s stop of Diggs. The court then shifted its focus to whether Patrolman Shupe

could frisk Diggs. Based upon the factual findings set forth above, the court was

satisfied that the frisk was justified. Therefore, the court denied Diggs’s motion to

suppress.

And, based on those findings, the Superior Court concluded that Patrolman

Shupe had made a reasonable investigatory stop and did not overstep constitutional

bounds when he conducted a limited protective search of Diggs’s person for

weapons. Therefore, the court denied Diggs’s motion to suppress.

 F.

After the CCDW and resisting-arrest counts were severed, Diggs proceeded

to trial on the PFBPP and PABPP counts. The jury found Diggs guilty on both

counts, and the court sentenced him to 18 years at Level V incarceration suspended

after 10 years for 18 months of Level III intensive supervision.37 Diggs then

appealed.

G.

Broadly speaking, Diggs raises two issues on appeal. First, he challenges the

Superior Court’s finding that Patrolman Shupe had a sufficiently particularized and

objective basis to detain him. In particular, Diggs contests the court’s invocation of

the “citizen informant” doctrine in its analysis of the reasonableness of the officers’

seizure of Diggs. Diggs also claims that the court’s factual findings regarding his

reaction to Shupe’s otherwise lawful approach were based on “an erroneous review

of the totality of the evidence and an unjustifiable disregard of contrary facts.”38

Second, Diggs argues—for the first time on appeal—that, when the Superior Court

made its suppression-hearing factual findings, it should have drawn an inference

adverse to the prosecution because it did not preserve and disclose information from

Diggs’s encounter with the police.

II.

This Court reviews a trial judge’s denial of a motion to suppress for an abuse

of discretion.39 Our review of the trial court’s legal conclusions, however, is de

novo.40 When the trial court denies the motion after an evidentiary hearing, our

review of its factual findings is deferential; the inquiry is whether there was

sufficient evidence to support those findings and whether they were clearly

erroneous.41

Diggs’ evidentiary argument—that the Superior Court was required to apply

a “‘lost and/or missing evidence’ inference”42 to its suppression-hearing factual

findings—was not raised in the Superior Court. Under this Court’s rules, “[o]nly

questions fairly presented to the trial court may be presented for review.”43 In other

words, an argument not made in the trial court is deemed to have been waived.

“[We] may excuse a waiver, however, if [we] find[] that the trial court committed

plain error requiring review in the interests of justice.”44 “Plain error is limited to

fundamental in their character, . . . [that] clearly deprive an accused of a substantial

right, or which clearly show manifest injustice.”45

III.

The Fourth Amendment protects the citizenry from unwarranted

governmental searches and seizures. Likewise, Article I, § 6 of the Delaware

Constitution provides that “[t]he people shall be secure in their persons, houses,

papers and possessions, from unreasonable searches and seizures.”46 Under the

exclusionary rule, evidence obtained by searches and seizures that violate these

guarantees is inadmissible.47 Diggs claims that the police unjustifiably seized him

during the store encounter and that, therefore, the evidence obtained as a result of

the seizure, i.e., the gun and ammunition, should have been suppressed under the

exclusionary rule.

Generally speaking, investigative encounters between law enforcement and

citizens fall within three categories: consensual encounters or mere inquiries,

(Del 1999) (“The exclusionary rule acts as a remedy for a violation of a defendant’s right to be
free of illegal searches and seizures. It provides for the exclusion from trial of any evidence
recovered or derived from an illegal search and seizure.”).
17
investigative detentions, and formal arrests. The category into which an encounter

fits depends on the nature and extent of the contact. A consensual encounter would

include—as happened initially here—a police officer asking the citizen a question.

Such an encounter is not a seizure under the Fourth Amendment or Article I, § 6 of

the Delaware Constitution and therefore no level of suspicion is required to support

it. As the United States Supreme Court put it in Florida v. Royer

law enforcement officers do not violate the Fourth Amendment by
merely approaching an individual on the street or in another public
place, by asking him if he is willing to answer some questions, by
putting questions to him if the person is willing to listen, or by offering
in evidence in a criminal prosecution his voluntary answers to such
questions.48
The next level of encounters—investigative detentions—are more intrusive

and are considered seizures under the Fourth Amendment and Article I, § 6.49

Typical investigative detentions include motor-vehicle stops and stops of persons

who are “abroad[] or in a public place.”50 Under Section 1902(c) of the Delaware

Criminal Code, such a detention “shall not exceed 2 hours . . . [and] is not an

arrest.”51 Under Delaware law, an arrest “is the taking of a person into custody in

48
Florida v. Royer, 460 U.S. 491, 499 (1983); see also Woody v. State, 765 A.2d 1257, 1283 n.3

order that the person may be forthcoming to answer for the commission of a

crime.”52

In this case, Superior Court found—and the parties do not dispute—that, when

Patrolman Shupe grabbed Diggs by the arm, Shupe transformed a consensual

encounter into an investigative seizure. Thus, under both federal and Delaware

constitutional law, it was incumbent upon Shupe “to point to specific and articulable

facts which, taken together with rational inferences from those facts, reasonably

warrant [the] intrusion.”53 In this Court’s words, an investigative detention “must

be justified at its inception by reasonable suspicion of criminal activity as defined in

Terry v. Ohio.”54 “A determination of reasonable suspicion must be evaluated in the

context of the totality of the circumstances as viewed through the eyes of a

reasonable, trained police officer in the same or similar circumstances, combining

objective facts with such an officer’s subjective interpretation of those facts.”55

This level of justification is often referred to as “reasonable articulable

suspicion” and is “‘considerably less’ than proof by a preponderance of the evidence

and less demanding than probable cause,”56 which is necessary to support an arrest.

In one effort to define the contours of reasonable suspicion, the United States

Supreme Court observed that “the concept . . . , like probable cause, is not ‘readily,

or even usefully, reduced to a neat set of legal rules.’”57

A.

Diggs now mounts a five-fold challenge to the Superior Court’s determination

that Patrolman Shupe’s detention of Diggs was supported by a reasonable articulable

suspicion. First, Diggs claims that the court’s conclusion that Marino’s informant

qualified as a “citizen informant” whose tip was presumptively reliable was

erroneous. Second, he contends that the presumption of reliability afforded to the

informant’s tip is an impermissible conclusive presumption under 11 Del. C. § 306.

Third, Diggs argues that the absence of any information about the informant’s basis

of knowledge—that is, how the informant came to know that the individual she

described was concealing a handgun in his waistband—rendered her tip unreliable.

Fourth, Diggs contends that Patrolman Shupe was not entitled to rely on the

information from Corporal Marino as the “sole basis”58 to stop Diggs. And fifth,

Diggs challenges the Superior Court’s finding that Diggs engaged in suspicious

informant’s tip that is “insufficient for . . . [an] arrest or search warrant” may nonetheless carry a
sufficient indicia of reliability for an investigative detention).

thereby providing the basis to conduct a limited search for weapons.

B.

Because our analysis of Diggs’s legal arguments is largely driven by the facts,

we take up Diggs’s challenge to the Superior Court’s factual findings first. The

thrust of Diggs’s complaint is that the court should have credited the testimony of

Bullock and Price, to the exclusion of Patrolman Shupe’s testimony, on two

important points. Specifically, Diggs notes that Bullock did not hear the officer say

anything before grabbing Diggs’s arm, and neither Bullock nor Price saw Diggs

throw anything. Thus, according to Diggs, the court should have rejected Patrolman

Shupe’s testimony that Diggs engaged in suspicious behavior, forcefully throwing

down his phone and cigar and assuming a defensive stand “like he was going to run

or fight,”59 in response to Shupe’s casual question.

As mentioned before, our review of the factual findings of the Superior Court,

following an evidentiary hearing on a motion to suppress is deferential.60 Findings

on credibility determinations, are subject to the “clearly erroneous” standard.61 And

“[w]here there are two permissible views of the evidence, the factfinder’s choice

between them cannot be clearly erroneous.”62

Here, the record supports two permissible views of the evidence as it related

to whether Shupe first asked to speak with Diggs and whether and to what extent

Diggs reacted strangely to Shupe’s approach, including whether Diggs threw items

to the floor and assumed a position indicative of an intent to fight or flee before

Shupe grabbed him by the arm. Shupe, recognizing that armed with the tip alone,

he needed “to get reasonable articulable suspicion that [Diggs] had a firearm before

[he] acted on it,”63 said that he intended to engage in a consensual encounter with

Diggs. But as soon as he asked Diggs if he could speak with him, Diggs responded

in a way that led Shupe to believe, based on his training and experience, that Diggs

not only might “run or fight” but that he might have been preparing to draw a

weapon.64

To be sure, Diggs’s witnesses perceived the event differently and in a way

that could cause a fact-finder to doubt whether Patrolman Shupe said anything to

Diggs before grabbing him and whether Diggs behaved precisely as Shupe

described. But each of those witnesses were subject to limitations on their ability to

see and hear what happened, and some were members of Diggs’s immediate family.

For instance, Bullock, who testified that he did not hear Patrolman Shupe say

anything to Diggs and did not see Diggs throw anything, acknowledged that his

attention was divided between the suspected shoplifters in the store and the

encounter in the store’s doorway. Price, who, like Bullock did not hear anyone say

anything to Diggs and did not see Diggs throw anything, was behind Diggs and

therefore had an obstructed view of the police officers. As Price recalled,

“[e]verything . . . happened so fast, so . . . [she didn’t] quite recall seeing [the

officers’] faces.”65 And the testimony of Na’Isha and Julia Pantoja—Diggs’s sister

and mother, respectively, and thus vulnerable to a charge of bias—was hampered by

the fact that neither was inside the store.

Under these circumstances, we cannot conclude that the Superior Court’s

adoption of Patrolman Shupe’s version of the encounter was clearly erroneous. To

be clear, had the court rejected Patrolman Shupe’s version and credited the equally

permissible view of the evidence Diggs favored, we could not conclude that such a

choice was clearly erroneous. But when presented with differing accounts of

historical facts, “it is the [trial court’s] role to resolve the conflicts in witnesses’

testimony and weigh their credibility.”66 In this case, the trial court thoughtfully

weighed the witnesses’ competing versions and made findings that were supported

by sufficient evidence. Consequently, we reject Diggs’s claim that those findings

were erroneous. Those findings, moreover, undercut Diggs’s legal arguments

which, to the extent necessary, we now take up in turn.

C.

The central thrust of the legal arguments Diggs presses on appeal—as

distinguished from his criticism of the court’s factual findings discussed above—is

that the Superior Court misapplied the so-called “citizen informant” doctrine when

it assessed the reasonableness of Patrolman Shupe’s conduct. Diggs leads with the

assertion that Corporal Marino’s informant was not in fact a citizen informant as that

term has been defined and follows with a critique of the reliability of the informant’s

tip and Patrolman Shupe’s minimal corroboration of it.

In contrast to the showing of credibility or reliability that is required when

evaluating a typical informant’s tip, under the “citizen informant” doctrine, the

reliability of information provided by “an average law abiding citizen performing a

civic duty by reporting a crime”67 is sometimes presumed. “The citizen-informer is

a passive observer with no connection with the underworld, and no reason to

fabricate what he has seen or heard, and as such is considered presumptively

67
Bailey, 440 A.2d at 999.
24
reliable.”68 The most typical application of this presumption of reliability involves

a “person appearing to be an average citizen [who] takes the initiative in

communicating to the police the fact that he has been a victim or a witness to a crime

such as robbery or assault.”69

In our view, Diggs rightly questions whether the suppression-hearing record

supports the Superior Court’s finding that Corporal Marino’s informant “was not a

member of the criminal community, but rather an individual who occasionally

telephoned police to report incidents of which he or she had knowledge.”70 Although

Corporal Marino described the informant as a “concerned citizen,”71 he did not

confirm that the informant was not of the criminal milieu. Additionally, it is

unclear—despite the State characterization of the informant as an “eyewitness”72—

whether the informant witnessed the described person possessing the firearm as

reported.

These gaps raise legitimate questions about the applicability of the “citizen

informant” doctrine here. What is more, the informant’s possession of Corporal

Marino’s personal cell phone number and her history of providing several tips over

a period of 11 years sets this informant apart from the typical “citizen informant.”

Yet because, as we explain below, the legality of the seizure of Diggs’s gun does not

turn exclusively on the reliability of the informant’s tip, we need not answer those

questions. The pertinent question instead is whether the additional facts that came

to light after Corporal Marino relayed the tip to Patrolman Shupe sufficiently

bolstered the tip regardless of the tipster’s classification. The question asked

differently is: even if we were to accept Diggs’s contention that Corporal Marino’s

tipster must be treated as an anonymous informant whose information is not

presumed to be reliable, did Patrolman Shupe’s later observations, coupled with the

tip and the minimal corroboration of it, create a reasonable suspicion of criminal

activity? Our answer is yes.

Before explaining this answer, we note that Diggs never confronts this issue

on these terms. Instead, he argues that Patrolman Shupe relied on the informant’s

tip, as relayed to him by Corporal Marino, as the “sole basis” for stopping Diggs.73

Diggs doubled down on this assertion at oral argument, claiming that “[t]his was all

driven by the tip and [that] this case is really about the tip and whether it provided

reasonable suspicion.”74 Alternatively, Diggs depicts his reaction to Patrolman

Shupe as merely “act[ing] in a way to avoid speaking to the police.”75 But we have

already rejected Diggs’s invitation to reduce the totality of the circumstances upon

which Patrolman Shupe based his decision to detain Diggs to the informant’s tip.

And Diggs’s watered down description of his reaction to Shupe’s approach cannot

be squared with Shupe’s description of the encounter—a description the trial court

credited and upon which we base our ensuing analysis.

D.

That the police seized Diggs, within the meaning of the Fourth Amendment

and Article I, § 6, in the entrance way of the store is not disputed. The parties’

positions are less clear, however, as to when the seizure took place. The Superior

Court found—and the State seems to concede—that Patrolman Shupe seized Diggs

when, after Diggs threw down his phone and cigar and assumed a defensive stance,

Shupe grabbed Diggs by the arm. For his part, in his briefs, Diggs assiduously

avoids identifying the point at which the encounter turned into a seizure. Yet Diggs

conceded at oral argument that Patrolman Shupe’s initial approach and inquiry of

Diggs did not constitute a seizure,76 and nowhere does he contest the trial court’s

75

76

27
determination that the seizure occurred when Shupe grabbed Diggs’s arm.

Consequently, our analysis focuses on the quantum of information Shupe possessed

at that time in determining whether Diggs’s detention was warranted.

The evidentiary record supports the conclusion that the following specific and

articulable facts were known to Patrolman Shupe before he detained Diggs.

Corporal Marino had informed Shupe that a reliable witness had told him that a

Black male, approximately 30 to 35 years of age and wearing a camouflage jacket,

was on the 200 block of South Harrison Street, which Shupe described as “a high

crime area.”77 According to the tip as relayed by Marino, the described individual

was “armed with a handgun, and it was in his waistband.”78

Shupe responded to the area “very quickly”79 and observed an individual—

Diggs—walking in a southerly direction on Harrison Street. Shupe watched as

Diggs entered the Shop Smart convenience store and eventually followed him there,

encountering Diggs in the doorway. There were several people, including children,

in the front of the store near the doorway.

Section 6 of the Delaware Constitution prohibited Officer Shupe from approaching
Mr. Diggs and asking to speak with him?

 When Shupe asked Diggs if he could speak with him, Diggs forcefully threw

down his cell phone and also discarded a cigar. Then Diggs assumed an odd stance,

which Shupe described alternatively as “defensive”80 and “athletic.”81 Based on his

training and experience, Shupe inferred that Diggs “was going into flight or fight

mode”82 and had placed his hands in “a good place to start to draw a firearm.”83 At

that point, Shupe’s belief that Diggs possessed a firearm solidified, and he “grabbed

a hold of Mr. Diggs’[s] arm . . . to detain him . . . [for] further . . . investigation.”84

That these facts, viewed in their totality, justified Patrolman Shupe’s

investigative detention of Diggs seems evident to us. One simple way to reach that

conclusion is to ask what Shupe was to do at each step along the way. Was it

improper for the officer to follow up on the tip by responding to the designated area

to determine whether an individual meeting the tipster’s description would be found

there? Of course not. Upon seeing such an individual there, was it unlawful for

Shupe to approach him and ask if the two might talk? Diggs himself answers this

question in the negative. So we are left with assessing the reasonableness of

detaining an individual who reportedly possesses a weapon in a crowded

convenience store and who reacts to a lawful inquiry by a uniformed police officer

not by declining, politely or otherwise, to speak with the officer but by acting in a

way that could be interpreted as aggressive, if not dangerous. Under these

circumstances, it was reasonable, in our view, for Shupe to suspect that the

informant’s tip was credible and that Diggs was armed or otherwise engaged in

criminal activity.85 Hence, the detention was reasonable and did not constitute a

violation of Diggs’s constitutional rights.

It follows from this conclusion that Patrolman Shupe’s protective search of

Diggs’s person for weapons was lawful.86 Diggs does not argue otherwise.87

E.

Our determination that the Superior Court’s factual findings were supported

by sufficient evidence and not clearly erroneous and our conclusion that, even in the

absence of the presumption of reliability assigned to the purported “citizen

85
To be clear, we do not hold today that the informant’s tip, standing alone, justified the detention
of Diggs, only that the tip, coming as it did from an informant with whom Corporal Marino was
familiar and who had previously supplied reliable information, was not entirely devoid of value
and was worthy of consideration under the “totality of the circumstances” test.

officer has stopped or detained to question as provided in § 1902 of this title, whenever the officer

weapon.”); see also State v. Rollins, 922 A.2d 379, 386 (Del. 2007) (“During a Terry stop, an
officer may conduct a limited protective search for concealed weapons. So long as the officer is
entitled to make a forcible stop, and has reason to believe that the suspect is armed and dangerous,
he may conduct a weapons search limited in scope to this protective purpose.”) (quotation marks
and footnotes omitted).

Diggs contends that the search of his person was unlawful but only because his detention was

informant,” Diggs’s detention and search were lawful, renders our consideration of

Diggs’s Section 306 argument unnecessary. Likewise, because our analysis of the

reasonableness of Patrolman Shupe’s suspicion is limited to his presumptively

reliable personal observations and the facts that Corporal Marino communicated to

him, we need not consider Diggs’s claim that the Superior Court violated the

“collective knowledge” doctrine as explained in State v. Cooley. 88

IV.

Diggs next argues that, because the investigating officers failed to collect and

preserve certain evidence—data from Marino’s and Shupe’s cell phone and the

store’s surveillance video—the Superior Court was required to draw a “lost/missing

evidence inference” when it determined the facts relevant to Diggs’s motion.

Despite his not having requested the court to adopt such an inference, Diggs

contends that the court’s failure to do so “resulted in the deprivation of [his] due

process right to a fair suppression hearing.”89 Diggs concedes that this claim is

subject to plain-error review as we have described it earlier.

 Diggs’s argument raises interesting questions regarding how a trial court,

sitting as the fact-finder in a pretrial evidentiary hearing that is not concerned with

the defendant’s guilt or innocence, should handle a claim that the State has failed to

collect and preserve arguably relevant evidence.90 But our standard of review—

plain error—obviates the need to take up those questions.

First of all, the relevance of the text messages and call logs on the officers’

personal cell phones is marginal at best—unless, of course, Diggs claims that the

officers’ testimony that they communicated by cell phone shortly before

apprehending Diggs was made up out of whole cloth. But that is not what Diggs

contends. Instead, he vaguely alleges that “[t]his evidence was relevant to the

suppression issues as it related to the circumstances of the tip, and the substance of

the information exchanged.”91 And what is more, Diggs does not identify a single

factual finding by the Superior Court that could have been undermined by the cell

phone records. Thus, we conclude that, even if the State had an obligation to

preserve and produce the officers’ cell phone data, Diggs has not shown that its

failure to produce them violated Diggs’s due process rights as Diggs alleges.

90
We are mindful of this Court’s determination that the prosecution’s obligation to disclose
exculpatory information can extend to pretrial proceedings and information not directly relevant
to guilt or innocence when the withholding of that information “deprives the defendant of an
opportunity to vindicate a possible deprivation of his constitutional rights.” O’Neil v. State, 691
A.2d 50, 54 (Del. 1997); see also Pierson v. State, 351 A.2d 860 (Del. 1976).
91
Opening Br. at 39.
32
 The same is true for Diggs’s claim that the failure of the police to collect and

preserve the store surveillance video resulted in a deprivation of Diggs’s due process

right to a fair suppression hearing. Diggs claims that the video was subject to

disclosure under Superior Court Criminal Rule 16 because he requested it, and

because it was potentially exculpatory and relevant to suppression issues. But Diggs

does not show how the video was in “the possession, custody, or control of the

state,”92 the sine qua non of the State’s discovery obligation.

On this last point, Diggs’s argument runs head-on into the Superior Court’s

factual findings.

After the arrest, Officer Shupe asked a person for the footage from a
camera located in the Market. Officer Shupe was told by a person
working at the Market that he did not know how to retrieve the footage.
At a later date, Officer Shupe went back and tried again to retrieve the
footage but, once again, was told that no one could retrieve the footage
and give it to him.93

Nevertheless, Diggs contends that “[t]he police had sufficient authority and

opportunity to secure the surveillance video, either through a search warrant or

subpoena.”94 Diggs cites no authority for this proposition, which, in fact, runs

contrary to our precedent.95 In short, Diggs demonstrated neither that the failure of
