Police and federal agents have been collecting information from Greyhound in an attempt to identify the suspect and are working to determine whether he purchased the ticket to New York in late November, the official said.
Investigators were also trying to obtain additional information from a cellphone recovered from a pedestrian plaza through which the shooter fled.
A tip that the shooter may have stayed at a hostel brought police Thursday morning to at least two such establishments on Manhattan’s Upper West Side, according to one of the law enforcement officials briefed on the investigation. The photos made public Thursday were taken in the lobby of the HI New York City hostel.
“We are fully cooperating with the NYPD and, as this is an active investigation, can not comment at this time,” hostel spokesperson Danielle Brumfitt said in an emailed statement.
Police released new photos Thursday of a person wanted for questioning in connection with Thompson’s killing.
The images, showing an unmasked man smiling in the lobby of a Manhattan hostel, add to a collection of photos and video that have circulated since the shooting — including footage of the attack itself, as well as still frames of the suspected gunman stopping at a Starbucks beforehand.
Investigators believe the suspect used a fake New Jersey identification card when he checked in at the hostel, said one of the officials who spoke with the AP.
Employees who work at the hostel told investigators they remembered a man who almost always wore a mask when interacting with them or passing by the front desk. That person wore a jacket that looked like the one worn by the man pictured in surveillance images released after the shooting, the official said.
After the shooting, police said the gunman fled on a bicycle and was last seen riding into Central Park.
Based on surveillance video and evidence from the scene, investigators believe the shooter had at least some firearms training and experience with guns and that the weapon was equipped with a silencer, one of the law enforcement officials told the AP.
Investigators were also looking into whether the suspect had pre-positioned a bike as part of an escape plan, the official said.
Security video shows the killer approaching Thompson from behind, leveling his pistol and firing several shots, barely pausing to clear a gun jam while the executive tumbled to the sidewalk. Cameras showed him fleeing the block across a pedestrian plaza before getting on the bicycle.
Police released several images of 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.
