6.Based on my participation in this investigation, my conversations with other law enforcement officers, my review of documents prepared by others, and my review of security camera video, I have learned, among other things, the following:
a.On December 4, 2024, at approximately 6:45 a.m., Brian Thompson (“the Victim”), the Chief Executive Officer of a nationwide health insurance company (“Company-1”), was shot and killed by a masked assailant (the “Shooter”) while walking on West 54th Street toward a hotel in Midtown Manhattan (the “Midtown Hotel”) where a Company-1 investor conference was scheduled to begin at 8:00 a.m. As discussed below, the Shooter was later identified to be LUIGI NICHOLAS MANGIONE, the defendant. Security camera video showed the Shooter, who was wearing a gray backpack (the “Gray Backpack”), come from between two parked cars, walk up behind the Victim, and shoot the Victim in the leg and back outside of the Midtown Hotel’s entrance on West 54th Street. The firearm the Shooter used appeared to have a sound suppressing device or “silencer” attached to the front of its barrel. A still image from the security camera video of the shooting is provided below:
b.Law enforcement personnel who responded to the scene of the shooting recovered, among other items, spent 9mm shell casings and at least one round of live 9mm ammunition. The words “deny,” “delay,” and “depose” were written on the side of the some of the shell casings. Responding law enforcement personnel also recovered a cellphone in the vicinity of the location where the shooting had occurred.
The Investigation
7.Based on my participation in this investigation, my conversations with other law enforcement officers, my examination of documents obtained through a court authorized search warrant, my review of documents prepared by others, and my review of security camera video, I know that over the course of the next several days, investigators retrieved and reviewed hundreds of hours of recordings from nearby security cameras to track the Shooter’s movements both before and after the murder. From that review, investigators were able to formulate the following timeline of the Shooter’s movements from November 24, 2024 up to and including December 4, 2024:
