New York City police continued searching on Thursday for the man who killed UnitedHealth executive Brian Thompson in a brazen attack outside a Midtown Manhattan hotel and was last seen fleeing into Central Park.
Thompson, the CEO of UnitedHealth's insurance unit, was shot from behind on Wednesday morning in what police described as a targeted attack by a masked assailant lying in wait. It came just before the company's annual investor conference at the Hilton on Sixth Avenue.
The words "deny," "defend" and "depose" were carved into the shell casings found at the scene, police sources told ABC and the New York Post. Reuters has not independently verified that information.
The words are similar to the title of a book critical of the insurance industry published in 2010: "Delay Deny Defend: Why Insurance Companies Don't Pay Claims and What You Can Do About It."
The author, Jay Feinman, a professor emeritus at Rutgers University Law School, declined interview requests from Newsmax and Reuters.
Investigators have not yet named a suspect and were still looking for a motive, the New York City Police Department said during a press conference on Wednesday morning. They have not provided a briefing since.
"Every indication is that this was a premeditated, preplanned, targeted attack," New York City Police Commissioner Jessica Tisch told reporters on Wednesday.
ABC News reported Thursday that police have sought a search warrant for a location in New York City where the suspect may have been staying, sources said.
Security video showed the shooter behind Thompson, 50, raising his handgun and firing at his back. Police said the gunman arrived outside the hotel several minutes before Thompson and waited for him to walk past before firing, ignoring other passers-by.
The suspect, wearing a hooded sweatshirt and ski mask and wearing a gray backpack, fled on foot before mounting an electric bike and riding into Central Park, police said.
Police published a number of photographs of the suspect taken from video cameras in the area, including one with the gun raised and pointed toward Thompson and another of the suspect fleeing on a bike.
Other photos captured a glimpse of his eyes, brow and the bridge of his nose as he stood in a cafe, with a caption asking the public for any help in identifying the man.
The killing took place on the morning of the city's annual Christmas tree lighting at Rockefeller Center a few blocks away. The event went ahead as planned under heavy security.
UnitedHealth is the largest U.S. health insurer, providing benefits to tens of millions of Americans, who pay more for healthcare than people in any other country. Thompson had been the CEO of UnitedHealthcare, a unit of UnitedHealth Group, since April 2021.
The company has been grappling with the fallout from a massive data hack of its Change Healthcare unit that provides technology for U.S. healthcare providers, disrupting medical care for patients and reimbursement to doctors for months.
Thompson had worked at UnitedHealth since 2004 in several divisions, according to a biography later removed from the company's website.
"Our hearts go out to Brian's family and all who were close to him," the company said in a statement.
Thompson's wife, Paulette, told NBC News on Wednesday that he had been receiving some threats related to his job, but was not specific. In a later statement she said, "Brian was an incredibly loving, generous, talented man who truly lived life to the fullest and touched so many lives."
Police in Minnetonka, Minnesota, where UnitedHealth is based and Minneapolis do not have any records of threats against Thompson.
In Maple Grove, Minnesota, where Thompson lived, police administrator Theresa Keehn told Reuters there were no reports of threats to Thompson, but there was one reported incident of "suspicious activity" at his home in June 2018.
Paulette Thompson was getting ready for bed when she reported seeing the deadbolt turning on their front door, the police report said. She hid in the bathroom "terrified," but police found no sign of an attempted break-in and no one on the property.
