Timeline: Brian Thompson's murder, Luigi Mangione's capture and fate

NEW YORK CITY - The timeline of events leading up to former United Healthcare CEO Brian Thompson's murder in New York City and Luigi Mangione's arrest in Altoona, Pennsylvania, paints a chilling picture of premeditated violence. 

Timeline:

Here's a detailed breakdown of the events – before and after the killing – according to an indictment released back in December:

Mangione arrives in New York City (Nov. 24)

• According to the indictment, on Nov. 24, Mangione arrived at Port Authority on a bus and checked into the HI New York City Hostel on the Upper West Side, using a fake New Jersey ID under the name "Mark Rosario."

• Mangione extended his stay multiple times, raising suspicions about his intentions.

Mangione stops at Starbucks before the murder (Dec. 4)

• According to the indictment, at 5:34 a.m., Mangione departed the hostel and traveled to Midtown Manhattan using an e-bike. His route led him to the area surrounding the Hilton Hotel.
• Between 5:52 a.m. and 6:45 a.m., Mangione was seen walking near and around the Hilton Hotel at 6th Avenue and West 54th Street. Surveillance footage captured his movements, though his purpose remained unclear at the time.
• At 6:15 a.m., Mangione stopped at a Starbucks (1290 6th Ave.) to purchase a water bottle and granola bars.
• Between 6:38 a.m. and 6:44 a.m., Mangione was observed standing silently against a wall on the north side of West 54th Street, directly across from the Hilton. He is fully masked, with his hood up, making his presence more discreet and raising suspicions about his intentions.

Brian Thompson is shot outside Hilton Hotel (Dec. 4)

• According to the indictment, at 6:45 a.m., Mangione crossed the street to the Hilton Hotel and approached Thompson from behind. Armed with a 9-millimeter 3D-printed ghost gun equipped with a silencer, Mangione allegedly shot Thompson twice – once in the back and once in the leg.

• After the shooting, Mangione fled the scene, heading northeast on West 54th Street, the indictment said. He then abandoned the e-bike and continued his escape uptown.

Mangione flees New York City (Dec. 4)

• Mangione hailed a taxi after abandoning the e-bike. The taxi dropped him off at West 178th Street and Amsterdam Avenue in Northern Manhattan. From there, he fled the state of New York, evading authorities for several days.

The CEO killer's suspected escape route.

United Healthcare CEO is pronounced dead (Dec. 4)

• Thompson was rushed to Mt. Sinai Hospital after being shot. Despite efforts to save him, he was pronounced dead at 7:12 a.m. The coroner confirmed that the cause of death was gunshot wounds.
• Authorities found two shell casings near the scene, each inscribed with the words "DENY" and "DEPOSE". Additionally, a bullet retrieved from the scene had the word "DELAY" written on it.

Mangione arrested in Altoona, Pennsylvania (Dec. 9)

• On Dec. 9, Mangione was spotted at a McDonald's in Altoona, Pennsylvania. Authorities quickly apprehend him, ending his days on the run.

• During the arrest, police recovered a 9-millimeter handgun with a 3D-printed receiver, two ammunition magazines, multiple live cartridges, a homemade silencer, and the fake New Jersey ID used at the hostel.

Mangione extradited back to New York City (Dec. 19)

• Mangione had been held in Pennsylvania since his arrest. At a hearing in Altoona, Mangione agreed to be returned to New York and was immediately turned over to at least a dozen NTPD officers who took him to an airport and a plane bound for Long Island.
• He then was flown to a Manhattan heliport, where he was walked slowly up a pier by a throng of officers with assault rifles – a contingent that included New York City Mayor Eric Adams and Police Commissioner Jessica Tisch.

Mangione pleads not guilty to murder, weapons charges (Dec. 23)

• Mangione pleaded not guilty to state murder and terror charges. The Manhattan district attorney had charged him with multiple counts of murder, including murder as an act of terrorism.

• Mangione's initial appearance in New York’s state trial court was preempted by federal prosecutors bringing their own charges over the shooting. The federal charges could carry the possibility of the death penalty, while the maximum sentence for the state charges is life in prison without parole.
• Prosecutors have said the two cases will proceed on parallel tracks, with the state charges expected to go to trial first.

Court proceedings for Mangione delayed several weeks (Jan. 6)

• Mangione was unlikely to appear in Manhattan federal court again before mid-February after prosecutors and lawyers last month requested more time to prepare the case for trial.
• The lawyers agreed in a letter to the court that the deadline to bring an indictment against Luigi Mangione can be extended to Feb. 17.
• Prosecutors said they consulted with the defense and agreed that extending the deadline was necessary "to permit both parties adequate preparation for pretrial proceedings and the trial itself."
