Video of the gunman leaving the scene of Wednesday's shooting of UnitedHealthcare CEO Brian Thompson showed him riding a bicycle to Central Park and later taking a taxi to a bus depot, Chief of Detectives Joseph Kenny told CNN.
“We have reason to believe that the person in question has left New York City,” Commissioner Jessica Tisch said.
The gunman made sure to conceal his identity with a mask during the shooting yet left a trail of evidence in view of the nation’s biggest city and its network of security cameras.
A law enforcement official said Friday that new surveillance footage shows the suspect riding the subway and visiting establishments in Manhattan and provided more clues about his actions in the days before the ambush.
The reason for the killing remains unknown. New York City police say evidence firmly points to it being a targeted attack.
Investigators believe the suspect may have traveled to New York last month on a bus that originated in Atlanta, according to the law enforcement official, who was not authorized to discuss details of the ongoing investigation and spoke to The Associated Press on condition of anonymity.
Once arriving in New York, he always appeared to pay with cash in establishments where he was captured on camera, the official said.
Investigators have tested a discarded water bottle and protein bar wrapper in a hunt for his DNA. They also were trying to obtain additional information from a cellphone recovered from a pedestrian plaza where the gunman fled after shooting Thompson outside his company's annual investor conference at a hotel just blocks from Radio City Music Hall and Rockefeller Center.
Police have released photos of the suspected shooter that were taken in the lobby of a hostel on Manhattan’s Upper West Side. The images, showing an unmasked man smiling in the lobby of the HI New York City hostel, add to a collection of photos and video circulated since the shooting — including footage of the attack itself, as well as images of the suspected gunman stopping at a Starbucks beforehand.
Surveillance images from the shooting show the man wearing a hooded jacket and a mask that concealed most of his face — a look that would not have attracted attention on a chilly morning.
Investigators have learned the man lowered his mask at the front desk of the hostel because he was flirting with the woman who checked him in, the law enforcement official told the AP, leading to a photo of his face. The woman told investigators that during that encounter she asked to see his smile and he pulled down his mask, the official said.
Investigators believe the suspect used a fake New Jersey identification card, the official said, when he checked in at the hostel, which has a café along with shared and private rooms and is just blocks from Columbia University.
Employees who work at the hostel told investigators they remembered a man who almost always wore a mask when interacting with them or walking by the front desk. The person wore a jacket that looked like the one worn by the man in surveillance images, the official said.
Investigators believe the shooter had at least some firearms training and experience with guns, the official said.
Security video shows the killer approaching Thompson from behind, firing several shots with a gun equipped with a silencer, barely pausing to clear a jam while the executive fell to the sidewalk.
