NEW YORK — Luigi Mangione, a person of interest in the murder of UnitedHealthcare CEO Brian Thompson, was taken into custody on Monday in Pennsylvania, nearly one week after the "brazen, targeted" shooting outside a Midtown Manhattan hotel on Wednesday, police said.
Here is a timeline of the suspect's whereabouts before, during and after the shooting:
Nov. 24
The killer entered New York City by bus on Nov. 24, when a surveillance camera at Port Authority Bus Terminal caught his arrival at 9 p.m., law enforcement sources told ABC News.
The inbound bus originated in Atlanta but it was not immediately clear where the suspect boarded.
He likely checked into a hostel on New York City's Upper West Side that day and later checked out, sources said.
Nov. 30
The suspect likely checked back into the HI New York City Hostel on the Upper West Side on Nov. 30, sources said.
Dec. 4 at 5 a.m.
At 5 a.m., nearly two hours before the shooting, the suspect was seen in surveillance footage outside the hostel on the Upper West Side, holding what appears to be an e-bike battery.
6:15 a.m.
At 6:15 a.m., surveillance footage reviewed by police shows someone who appears to be the suspect leaving a 57th Street subway station near the crime scene, police sources told ABC News.
6:19 a.m.
New cleared CCTV video shows a man who appears to be the suspect walking west on 55th Street at 6:19 a.m. The video shows him stoop down as he appears to momentarily drop an object on the garbage before continuing to walk.
Before the shooting
Sometime before the shooting, the suspect is spotted at a Starbucks. The exact time is not clear.
6:29 a.m.
The suspect appeared to walk past a parking lot on West 54th Street at 6:29 a.m. -- across the street some 50 meters from the site of the shooting.
6:44 a.m.
At 6:44 a.m., the masked gunman fatally shot Brian Thompson in front of the north entrance to the New York Hilton Midtown.
"The shooter then walks toward the victim and continues to shoot," NYPD Chief of Detectives Joseph Kenny said. "It appears that the gun malfunctions, as he clears the jam and begins to fire again."
The shooter fled on foot into an alley, where a phone believed to be linked to the suspect was later recovered, police sources said.
Time unknown
The suspect then fled north on a bike and rode into Central Park, police said.
Time unknown
After making his getaway on a bike, the suspect exited Central Park at 77th Street and Central Park West.
At 86th Street and Columbus Avenue, the suspect ditched the bike and took a taxi to the Port Authority bus facility at 178th Street.
Police believe he boarded a bus there and left New York City.
