In a full-fledged opinion by Justice Mastro, the Second Department affirmed the defendant’s murder conviction.  One piece of evidence against the defendant was location-data based on the use of defendant’s cell phone.  The Second Department determined there was no need for a Frye hearing before expert testimony about cell-phone location was presented because no novel scientific theory was involved. The Second Department also determined prior crimes demonstrating a similar unique pattern to that of the charged offense were admissible to prove identity.  With respect to some of the prior crime evidence, which did not sufficiently match the pattern of the charged crime to be admissible on the issue of identity, the erroneous admission of that evidence was deemed harmless. In discussing the prior-crime evidence, the court wrote:

In this case, the evidence of other crimes was offered to establish the defendant’s identity as [the victim’s] killer. Such evidence may be admitted if, as a threshold matter, the defendant’s identity is in issue and is not “conclusively established” by other evidence …, and it is demonstrated by clear and convincing evidence that the defendant is the same person who committed the other crimes …. Here, it cannot be said that the defendant’s identity as the killer was conclusively established so as to warrant the preclusion of other crimes evidence to prove identity. Indeed, while the evidence that the defendant was the person who killed [the victim] was compelling, it was also entirely circumstantial. Moreover, the defendant vigorously contested the identification issue and presented as a defense the assertion that his employer… had been the actual killer. Thus, the identity of the murderer was a disputed issue in the case, and any admissible evidence tending to establish identification was relevant… . People v Littlejohn, 2013 NY Slip Op 07063, 2nd Dept 10-30-13
