NYPD releases two new photos of the man wanted in the murder of UnitedHealthcare CEO

The New York Police Department released two new photos Saturday of a person wanted in the murder of UnitedHealthcare CEO Brian Thompson.

The photos are the latest in a series from the NYPD of the same person wanted for questioning in Wednesday’s killing.

The person can be seen in one of the photos through the partition of what appears to be a New York City taxi, wearing a blue medical mask and a black hoodie.

The other photo, taken from a car, shows the man outside the window walking next to the vehicle while wearing the same blue mask and a dark-colored puffer jacket with the hood pulled over his head.

The NYPD has said investigators were able to track some of his movements by taxi.

As the investigation into Thompson’s murder and manhunt for the gunman continued Saturday, three sources familiar with the investigation told NBC News there was still no identification of the person in question.

The FBI, Crime Stoppers and the NYPD are jointly offering a $60,000 reward for information leading to the shooter’s arrest.

Thompson was shot outside the Hilton Midtown hotel in New York on Wednesday morning as he headed to the UnitedHealth Group investor conference, officials said.

Thompson was shot at least once in the back and once in the right calf. He did not travel with security.

“Based on the evidence we have thus far, it appears the victim was specifically targeted,” NYPD Chief of Detectives Joseph Kenny said earlier this week. “But right now we don’t know why.”

New York Police Commissioner Jessica Tisch said Wednesday that it was a “premeditated, pre-planned targeted attack.”

The shell casings found at the scene had the words “deny,” “slow” and “depose” written on them, police said.

Police also found a gray backpack in Central Park that the person in question was believed to have had with him at the time of the murder. Officials were investigating whether it was indeed the same bag, two senior law enforcement officials told NBC News.

Police found a cellphone near the crime scene and investigators are trying to use it to learn more about the man’s contacts and movements, two sources familiar with the investigation said.

Four sources familiar with the investigation told NBC News on Saturday that no weapon was found in the backpack. Three sources said a jacket was in the bag, but it remains unclear whether this is the jacket the gunman was wearing at the time of the shooting.

Authorities believe the man wanted in connection with the murder may have left the state.

Kenny told reporters that the video shows the man riding a bicycle in Central Park and then taking a taxi to the Port Authority bus station near the George Washington Bridge.

Investigators are looking for additional video footage to determine if he boarded a bus from there, and if so, which one.

Police believe he traveled to New York City from Atlanta on a Greyhound bus last month, three senior law enforcement officials familiar with the case told NBC News. The bus arrived in New York on Nov. 24, after several stops along the way, they said.

Officials in New York are investigating whether they can find a name used for the Nov. 24 trip, and both the Atlanta Police Department and Greyhound are assisting in the investigation.

While in New York, the man stayed at a hostel on Manhattan’s Upper West Side, the NYPD said during a Friday briefing. Authorities are investigating whether he paid in cash and used a fake ID to rent a room there.

Roommates at the hostel said he kept his mask on all the time, even while eating, and only pulled it down to take a snack, the NYPD said.

Thompson’s wife, Paulette Thompson, told NBC News on Wednesday that her husband had received threats but was unclear about their nature.

“There had been some threats,” she said. “Basically, I don’t know, a lack of coverage? I don’t know any details. All I know is that he said there were people threatening him.”
