OPINION OF THE COURT
NYGAARD, Circuit Judge.In this case, Appellant Wayne Whittaker claimed that his car was stolen without his knowledge or consent. The FBI presented evidence that he had taken part in an “insurance give-up” scheme. We are required to determine whether the evidence used to convict Whittaker of mail fraud is sufficient. Whittaker makes two arguments. First, he contends that the District Court violated the corpus delicti rule by allowing the Government to use several statements that he made to the FBI. Second, he asserts that the District Court erred by not granting a judgment of acquittal because the evidence was insufficient to support the verdict. After analyzing the relevant case law and scouring the record, we reject both arguments, and affirm.
I.
A rash of automobile thefts in Philadelphia in the early 1990s prompted the FBI to set up a stolen car task force. The task force uncovered a secret location in the city where a theft ring maintained a “chop shop” known as the “Hacienda.” A chop shop is a place where stolen cars are disassembled and sold, piece-by-piece, to often complicit repair and body shops. Like social security numbers, every vehicle has a different vehicle identification number (“VIN”), which is affixed to various parts of the vehicle. Once separated from the chassis, the vehicle parts do not carry VINs, or their VINs are removed, so the parts can no longer be identified.
An FBI informant working in the Hacienda gave the FBI information about the car thefts that passed through the chop shop, including “insurance give-ups.” An insurance give-up is a vehicle that is turned in to the chop shop by or on behalf *699of someone trying to collect insurance money by reporting the vehicle stolen. Both parties benefit from this scheme: the vehicle owner gets insurance money and out of any lease payments, and the car thief gets a car.
Appellant’s 1998 Jeep Cherokee, identified by its VIN plates, was delivered to the chop shop. At the time of its arrival, there was evidence that the car was an insurance give-up: testimony showed that there was no damage to the steering column, door locks, or windows, and that the key was in the ignition.
During a subsequent interview with the FBI about the car theft, Whittaker admitted that he had participated in two phone conversations with an individual who offered to “get rid of’ his vehicle as an insurance give-up. Whittaker told the FBI that, during the second phone call, he informed the caller that he was not sure he wanted to go through with the scheme. He did not tell the man not to take his car.
The Government prosecuted Whittaker, and a jury found him guilty of one count of mail fraud, 18 U.S.C. § 1341. Whittaker moved for a judgment of acquittal, but the District Court denied the motion. Whit-taker’s motion for reconsideration was also denied and he was sentenced to five years probation, six months of home detention, and restitution of $26,543. He timely filed a notice of appeal. The District Court had jurisdiction of the violation of 18 U.S.C. § 1341 under 18 U.S.C. § 3231, and we have jurisdiction over the appeal pursuant to 28 U.S.C. § 1291.
II.
Because the District Court’s decision regarding the admissibility of Appellant’s statements following an objection on corpus delicti grounds is one of law, our review is plenary. United States v. Serafini, 233 F.3d 758, 768 n. 14 (3d Cir.2000).
A.
The Supreme Court has held that in order to sustain a conviction based upon a confession or admission on the part of the defendant, the statement of the defendant must be corroborated by some evidence of the corpus delicti (“the body of the offense” or the “essence of the crime”). Opper v. United States, 348 U.S. 84, 93, 75 S.Ct. 158, 99 L.Ed. 101 (1954).1 The purpose of the corpus delicti doctrine is to prevent convictions of criminal defendants based solely upon untrue confessions. Warszower v. United States, 312 U.S. 342, 347, 61 S.Ct. 603, 85 L.Ed. 876 (1941). According to the corpus delicti “trustworthiness” principle, confessions and admissions must be corroborated by “substantial independent evidence which would tend to establish the trustworthiness of the statement.” Id.; United States v. Wilson, 436 F.2d 122, 123 (3d Cir.1971).
In a corpus delicti analysis, sufficient evidence establishing the trustworthiness of the statements at issue is the critical consideration. Government of the Virgin Islands v. Harris, 938 F.2d 401, 408 (3d Cir.1991). In order to establish corpus delicti, the Government need prove only that a crime has been committed; identifying the defendant as the perpetrator of the *700crime is not required. Id. Finally, the confession can prove itself trustworthy if it discloses facts that were unknown to anyone other than the criminal. Id. at 403; Wilson, 436 F.2d at 123.2
B.
The admissions at issue took place with FBI Special Agent Jennifer Usleber. When Usleber confronted Whittaker with evidence of an insurance give-up, he seemed “visibly nervous.” App. 406. He then admitted that an unknown caller called him and said, “I understand you have something you want to get rid of.” App. 409. When he asked the caller to clarify, the caller said, “your vehicle,” and then, ‘We can make it disappear.” App. 410. Whittaker admitted that he listened to the caller’s proposition, and provided the caller with details about his car: the make, model, color, license number, and where it would be parked. App. 411-12. After Whittaker asked the caller what more he needed to do, the caller replied, “Nothing.” App. 412. In response to Usleber’s asking Whittaker what he thought would happen after this call, Whittaker said that he figured his car would be taken, and that he would be able to get out from under the lease. App. 412. Whittaker also described a second phone call during which he told the caller he had second thoughts. App. 415. But he admitted to Usleber that he did not tell the man not to take his car, and he did not do anything, such as park his car in a different location, that would have prevented it from being stolen. M
C.
Whittaker asserts that his conviction is based on this confession to the FBI agent, and that these statements are not corroborated by substantial independent evidence which would tend to establish the trustworthiness of the confession. This argument fails, for we conclude that there is sufficient evidence to establish the trustworthiness of Appellant’s statements to the FBI.
William Stauffer, the informant working in the Hacienda, testified that when he first entered Whittaker’s black Jeep Cherokee, the keys were in the ignition and there was no damage to the steering column, doors, or windows. App. 219-21. Frank Ozga, the operator of the Hacienda, also testified that he was provided with keys to the Jeep, and that there was no damage to the steering column, doors, or windows. App. 148. Whittaker testified that he not only locked the car, but that he also used The Club™ to lock the steering wheel, and activated the car alarm. A jury could have believed the testimony of Stauffer and Ozga, and disbelieved Whittaker’s testimony that he left his Jeep, locked, alarmed, and Clubbed, and that he was the only person who had keys to it. App. 298, 310, 327.
Whittaker told Police Officer Rivera, who took the initial stolen vehicle report, that he left his Jeep parked on the street on a Friday, and returned Sunday night to find it stolen. Ozga testified that he would instruct the person surrendering the vehicle not to report the vehicle stolen for “three days to a week” to give him time. App. 91-92. A jury could have drawn an inference from Whittaker’s three-day trip that this instruction had been communicated to him.
When Officer Rivera took the initial report from Whittaker, Whittaker told him *701that there were no financial arrearages on the vehicle. App. 299. Not only were there financial arrearages on the Jeep Cherokee, but Whittaker was especially anxious about those arrearages. According to a Collection Department Supervisor at World Omni Financial Corporation (“the leasing company”), in April and May, after a World Omni customer account representative told Whittaker that he was significantly behind on his payments, the representative had discussions with Whit-taker about the options of his voluntary surrender of the Jeep or the refinancing of the vehicle. App. 389. Whittaker was told that, had he elected to surrender his vehicle voluntarily to World Omni, the leasing company would take possession of the vehicle, sell it at auction, and pursue Whittaker for any outstanding balance still owing.3 Because of an accident that Whittaker had been in four days before the Jeep was reported stolen, which required repairs of an estimated $1,300, App. 349, this outstanding balance would have been even greater. Whittaker testified he was not making his payments at the time because he “didn’t have the money.” App. 562. In addition, Whittaker was told by World Omni that a voluntary surrender of the Jeep would have a negative effect on his credit file. App. 614. We conclude that a jury could have inferred an insurance give-up motive from Whittaker’s automotive financial dire straits. A jury could have also decided that Whittaker lied to the police officer about his arrearages in order to cover up his crime.
Other important circumstantial evidence against Whittaker includes testimony by Ozga that he was contacted by Leonard DeWolfson, Sr. (for whom Ozga had done “insurance jobs” in the past), who said that he had a black Jeep Cherokee insurance job which he wanted to pass to the Hacienda. App. 93-94.4 Also, Michael Dyke, who is Ozga’s stepson and who worked for Ozga in the Hacienda, corroborated Ozga’s testimony that the Jeep was an “insurance job” and that the DeWolfsons provided the keys with the car. App. 175-76.
Whittaker argues that because one would have to drive around for “forty or more minutes” looking for a parking spot in his Philadelphia neighborhood, it would never be possible to tell anyone with any certainty where he would park his car with regularity. App. 564. This argument overstates the car thief s task: the thief could easily cover the neighborhood looking for a particular car in a matter of minutes.
Finally, the nature of Whittaker’s statements doom his argument. If the confession itself discloses facts that were unknown to anyone other than the criminal, the confession can prove itself trustworthy. Harris, 938 F.2d at 403. In Harris, an appeal from a conviction for first-degree murder where no body was recovered, the defendant argued that the evidence obtained independent of his confession did not satisfy the trustworthiness doctrine. Id. In affirming the conviction, we held that as long as the evidence was substantial and proved trustworthy, the doctrine was satisfied. Id. at 410. We stated that this could be done in any number of ways, most notably by the detailed confession itself, if it demonstrated knowledge unknown to anyone other than the criminal. *702Id. In affirming the conviction, we held as sufficient evidence that the victim and the defendant had displayed acts of violence toward each other and that the victim had sought to avoid the defendant for fear of her life. Id. at 417-18. Essentially, we held that even in homicide cases, where no body or murder weapon has been recovered, a defendant’s statements concerning how the killing was carried out, corroborated by circumstantial evidence that there was a homicide, support the admissibility of those statements. In this case, Whit-taker’s statements about this contact with the car thief disclosed the way in which the insurance give-up scheme operates: the individual who wants an insurance job is contacted, and asked for a description of the car, the license plate number, and where it would be parked. Therefore, Appellant’s statements about his contact with a man who identified himself as a ear thief for “insurance jobs,” corroborated by circumstantial evidence that there was an insurance job, support the admissibility of those statements.
In sum, because the record evidence is sufficient to establish the trustworthiness of Whittaker’s statements and satisfy the requirements of the corpus delicti doctrine, the statements are admissible.
III.
When reviewing a district court’s decision regarding sufficiency of the evidence, we apply “a particularly deferential standard of review when deciding whether a jury verdict rests on legally sufficient evidence____ [W]e must view the evidence in the light most favorable to the government, and will sustain the verdict if any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.” United States v. Dent, 149 F.3d 180, 187 (3d Cir.1998) (citations omitted). After scouring the record, we conclude that there was more than sufficient evidence that Whittaker gave up his Jeep Cherokee as part of an insurance fraud scheme.
To convict Whittaker of mail fraud, the Government had to establish (1) his knowing and willful participation in a scheme to defraud, (2) with the specific intent to defraud, and (3) the use of the mail or interstate wire communications in furtherance of the scheme. United States v. Antico, 275 F.3d 245, 261 (3d Cir.2001).
Whittaker’s admission to the FBI, described above, is quite condemning. Further, the jury could choose to believe that his story to the FBI was not the entire truth: that he had more than two conversations with the caller, or that the telephone calls were different than the way he described them. The jury could have determined that Whittaker told Usleber about the two calls because he realized that the FBI might have phone records. See United States v. Voigt, 89 F.3d 1050, 1090-91 (3d Cir.1996) (stressing that the jury may reject the defendant’s proffered interpretation and accept the government’s, and that we draw all reasonable inferences in favor of the jury’s verdict).
Whittaker testified that he never told any friends, family members, or the insurance company about the calls. App. 580-81. The calls “didn’t stick into [his] mind,” and after his Jeep was stolen, the calls “didn’t really pop into [his] mind” until a month later. Id.
Whittaker asserts that because of a discrepancy between the date of the mailing in the indictment and the evidence presented at trial concerning the actual date of mailing, the government “failed to prove what it alleged in the complaint.” This argument is meritless because time is not an essential element of mail fraud, and proof of the acts charged, before the in*703dictment and within the statute of limitations, is normally sufficient. United States v. Somers, 496 F.2d 723, 745 (3d Cir.1974). This variance did not deprive Whittaker of due process because he was sufficiently apprised of the charge against him such that he was not prevented from mounting a stronger or different defense. See United States v. Crocker, 568 F.2d 1049, 1059 (3d Cir.1977).
We conclude that the Government’s evidence is sufficient for a conviction, and that the jury did not base its verdict on mere speculation. Whittaker’s admissions concerning the telephone conversations are incriminating; the jury’s conclusion that the disappearance of his Jeep flowed from the conversations does not rest merely upon conjecture. Whittaker’s financial motivation and his attempts to escape the lease in talks with World Omni provide motive. Finally, evidence shows that the undamaged Jeep arrived at the Hacienda with the key.
IV.
For the reasons discussed, we will affirm the District Court.
. Although the discussion of the corpus delicti doctrine pertains to the admissibility of evidence, not the sufficiency of evidence to convict, Government of the Virgin Islands v. Harris, 938 F.2d 401, 409 (3d Cir.1991), our analysis of both the corpus delicti doctrine and the legal sufficiency of the evidence necessarily overlap. See, e.g., United States ex rel. Hayward v. Johnson, 508 F.2d 322, 330 (3d Cir.1975) (holding that several pieces of circumstantial evidence “both satisfy the corpus delicti rule and provide sufficient evidence for the jury----”).
. The requirement that the corpus delicti be established by evidence independent of a confession is different from the requirement that there be independent evidence establishing the truthfulness of the confession.
. Whittaker testified at trial that World Omni wanted to charge him $29,000 for his Jeep Cherokee, which only had a book value of between $19,000 and $21,000. App. 557.
. This testimony was enhanced by Ozga’s details, such as that he "negotiated” with De-Wolfson, that DeWolfson’s son dropped off the Jeep, and that he had paid the DeWolfsons $300. App. 95-96.
