Murder of UnitedHealthcare CEO: New image shows suspect in back of taxi

New York: The New York Police Department has released two new images of the man it believes fatally shot the CEO of UnitedHealthcare, including one showing him in the back seat of a taxi on the day of the shooting.

The images were released late Saturday as the frantic investigation continued to identify and track down the killer of Brian Thompson, 50, the health care executive gunned down outside the New York Hilton Midtown hotel in Manhattan on Wednesday.

One image, captured from the front of the cab, appears to show the unidentified suspect peering forward from the vehicle's back seat with his face partially obscured by a blue surgical mask, a dark hat and a black hood. The other image, apparently recorded through a window, shows the man walking on the street wearing the same mask, a black puffer jacket and a hood pulled over his head.

Police have said that the man caught a taxi around 7 a.m. Wednesday on the Upper West Side, about 15 minutes after he shot Thompson. He took the cab uptown to a bus terminal near the George Washington Bridge, where they believe he may have caught a bus out of the state.

Although the killing set off a search that stretched well beyond New York City and commanded days of national attention, the man remained at large Sunday, and police were still searching for information about who he was and what had motivated him to shoot Thompson.

The taxi images are the latest to emerge as the police scour thousands of hours of footage from surveillance cameras around the city to glean information about the man's movements on the day of the killing. They also recovered bullet casings at the scene with the words "depose," "deny" and "delay" written on them -- a possible reference to terms used by insurers to avoid paying claims.

Officers also recovered a backpack in Central Park on Friday that they believe the man may have discarded as he cycled away from the scene of the shooting toward the Upper West Side, before he caught the cab. They had yet to publicly confirm if the backpack belonged to the man or contained any items of value to the investigation.
