We respectfully dissent in part. We agree with the majority that Supreme Court properly granted those parts of defendants’ omnibus motions seeking dismissal of count one of the indictment, for intentional assault in the first degree (Penal Law § 120.10 [1]), as duplicitous. We conclude, however, that the court erred in granting those parts of the motions seeking dismissal of count two of the indictment, for depraved indifference assault in the first degree (§ 120.10 [3]), inasmuch as that count is not duplicitous.
From August 2004 to April 2005, the victim resided with his daughter and defendants. The victim, a 51-year-old man, was afflicted with multiple sclerosis. On April 7, 2005, emergency medical personnel responded to a call from the victim’s daughter, whereupon they found the victim in the basement of his home. The victim was unresponsive, hypoglycemic and hypothermic. He was transported to the hospital, where it was determined that his body temperature was 80.6 degrees. His injuries included hand and facial fractures, as well as severe burns. Following a police investigation, defendants were charged with the two counts of assault based on 10 incidents that occurred “on or about and between August 1, 2004 and April 7, 2005.” Those 10 incidents are as follows:
1. Defendant Amber Bauman bloodied the victim’s nose with an aluminum baseball bat;
2. Bauman kneed the victim in the ribs and punched him repeatedly;
3. Defendant Charles Edward Lafler burned the victim’s arm, using a pan;
4. Lafler “dragged” the victim into a bathtub filled with hot water, and the water burned the victim’s feet;
5. Lafler hit the victim with a hammer, both on one of his hands and on his penis;
*3216. Lafler hit the victim in the back with his fists when the victim refused to eat cat feces;
7. Lafler hit the victim in the face on April 6, 2005, because he believed that the victim had sexually abused defendants’ children;
8. Defendants often punched the victim in one of his eyes;
9. Defendants attached the hose of a running vacuum cleaner to the victim’s penis; and
10. Defendants occasionally locked the victim in a cold room in the basement, where he was discovered on April 7, 2005.
In our view, depraved indifference assault must be considered a continuing crime. As set forth in 6 NY Practice, Criminal Law § 5:7, depraved indifference assault is established in the following circumstances:
“First, the defendant must cause serious physical injury rather than only physical injury. Second, his [or her] conduct must create not merely a ‘substantial’ and unjustifiable risk of physical injury, but a ‘grave risk of death.’ Third, he [or she] must act not only with a mens reas of recklessness, but with an additional mens rea of ‘depraved indifference to human life.’ To establish the latter mens rea, his [or her] conduct must reflect an ‘utter disregard for the value of human life’ and reflect ‘wickedness, evil or inhumanity, as manifested by brutal, heinous and despicable acts’ ” (see also People v Dickerson, 42 AD3d 228 [2007], lv denied 9 NY3d 960 [2007]; People v Britt, 283 AD2d 778 [2001], lv denied 96 NY2d 916 [2001]).
We thus conclude that depraved indifference assault is akin to the crimes of endangering the welfare of a child or depraved indifference murder, because it is “a crime that by its nature may be committed either by one act or by multiple acts and readily permits characterization as a continuing offense over a period of time” (People v Keindl, 68 NY2d 410, 421 [1986]; see People v Brammer, 189 AD2d 885 [1993], lv denied 81 NY2d 967 [1993]).
Based on our conclusion that depraved indifference assault is a continuing crime, we are then faced with the issue of duplicity.
“A duplicitous count of an indictment. . . joins two or more distinct and separate offenses in the same *322count. If a crime is defined by the performance of one act, the count that alleges the crime must allege only that act. Charges are not duplicitous if each count alleges a single incident or offense, or if the acts charged constitute a continuous crime” (41 Am Jur 2d, Indictments and Informations § 207 [emphasis added]; see People v First Meridian Planning Corp., 86 NY2d 608, 615-616 [1995]; Keindl, 68 NY2d at 417-418).
An individual’s guaranteed rights pertaining to indictments, as set forth in CPL 200.30 and 200.50, “guarantee three fundamental notions proclaimed repeatedly in case law” (People v Butler, 161 Misc 2d 980, 982 [1994, Berman, J.]). The first ensures that a defendant has notice of the charges against him or her and of the manner, time, and place of the conduct underlying the charges, to enable the defendant to prepare an answer. “The second entails a defendant’s right to be brought to trial by means of an indictment containing allegations with sufficient precision ‘to enable the defendant, once convicted, to raise the constitutional bar of double jeopardy against subsequent prosecutions for the same offense’ ” (id.). The third, concerning the requirement of specificity and the prohibition against duplicity, “ ‘ensures the reliability of the unanimous verdict’ ” (id.). Indeed, “[i]f two or more offenses are alleged in one count, individual jurors might vote to convict a defendant of that count on the basis of different offenses; the defendant would thus stand convicted under that count even though the jury may never have reached a unanimous verdict as to any one of the offenses” (Keindl, 68 NY2d at 418).
The test for duplicity that has evolved is whether, under a particular count alleged to be duplicitous, a defendant can “be convicted of [any] of the crimes charged therein, should the district attorney elect to waive the other[s]” (People v Klipfel, 160 NY 371, 374 [1899]; see Butler, 161 Misc 2d at 984). In People v Buckley (75 NY2d 843 [1990]), the Court of Appeals further elaborated on the test promulgated in Klipfel. In Buckley, the defendant was convicted of criminal possession of stolen property in the second degree (Penal Law § 165.45 [former (1)]), based upon his possession, along with his codefendants, of four stolen radar detectors that were owned by four different individuals, the aggregate value of which exceeded $250. Individually, however, the four stolen radar detectors did not have a value in excess of $250. Defense counsel contended that, *323because the four stolen radar detectors each belonged to different owners, each stolen radar detector amounted to a different offense (see Buckley, 75 NY2d at 845-846). In rejecting that contention, the Court of Appeals determined that the disputed count of the indictment was not duplicitous pursuant to the test promulgated in Klipfel inasmuch as none of the radar detectors had a value in excess of $250 and the defendant in Buckley thus could not have been convicted of the crime charged with respect to any single radar detector. The Court further rejected the defendant’s contention that the stolen property was required to have belonged to only one owner. The analysis of the Court of Appeals in Buckley establishes that “the gravamen of the offense [of criminal possession of stolen property in the second degree] is the knowing possession of stolen property[,] and the character of the act is not affected by the fact that the property may have belonged to several owners rather than one” (id. at 846).
Gravamen is the essence of a claim (see Black’s Law Dictionary 721 [8th ed 2004]). Here, the gravamen of the act of depraved indifference assault is that the defendants acted with depraved indifference. The character of the act is defined by the ongoing abuse of the victim, which resulted in both serious physical injury and a grave risk of death. In view of our determination that depraved indifference assault is a continuing crime, we are compelled to conclude that there was only one occasion on which defendants’ conduct resulted in serious physical injury and a grave risk of death, i.e., on April 7, 2005. We thus conclude that count two of the indictment is not duplicitous because it alleges a continuing offense with a series of serious physical injuries culminating in a grave risk of death on one occasion.
Finally, we note that, as the Court of Appeals stated in the context of depraved indifference murder, “a brutal, prolonged and ultimately fatal course of conduct against a particularly vulnerable victim” is a prime example of depraved indifference (People v Suarez, 6 NY3d 202, 212 [2005]). Such a course of conduct must necessarily involve multiple incidents. If one were to contend that the inclusion of multiple incidents renders a depraved indifference count duplicitous, then it would be impossible to prove an allegation of “a brutal [and] prolonged . . . course of conduct” in support of a charge of depraved indifference. The allegations of depraved indifference assault in this case, if proven, establish the requisite shocking and callous *324conduct toward a particularly vulnerable victim over a prolonged period of time. For that reason, we dissent in part.
Accordingly, we would modify the order by denying those parts of defendants’ omnibus motions seeking dismissal of count two of the indictment and reinstating that count of the indictment, and we would remit the matter to Supreme Court for further proceedings on count two of the indictment.
