NEW YORK (AP) -- Brian Thompson, the CEO of UnitedHealthcare, was fatally shot outside a hotel in midtown Manhattan where he was scheduled to speak at an investor meeting Wednesday morning, according to a person briefed on the investigation.

The person spoke on the condition of anonymity because they were not authorized to speak on the investigation.

Police did not release the victim's name, but said a 50-year-old was shot around 6:45 a.m. outside a Hilton before the shooter fled.

The victim was taken to a nearby hospital but could not be saved.

The preliminary police investigation indicated the shooting was not random, according to Mayor Eric Adams.

"It appears as though this was a targeted murder," he said.

UnitedHealthcare is the insurance arm of the health care giant UnitedHealth Group Inc. The Minnetonka, Minnesota-based company was scheduled to have its annual meeting with investors in New York City to update Wall Street on the company's direction and expectations for the coming year, according to a company media advisory. An announcement was made to attendees Wednesday morning that the conference was ending early.

The Hilton is in a bustling part of Manhattan, a short walk from tourist sites such as the Museum of Modern Art and Rockefeller Center, and often dense with tourists and office workers on weekday mornings. The popular Rockefeller Center Christmas Tree lighting is set to take place Wednesday evening.

Part of the block where the shooting took place was cordoned off with police tape, with a large contingent of police officers at the scene. Many security cameras are nearby.

Thompson had served as CEO for more than three years and had been with the company since 2004.

Minnesota Gov. Tim Walz tweeted that the state is "sending our prayers to Brian's family and the UnitedHealthcare team."

"This is horrifying news and a terrible loss for the business and health care community in Minnesota," the Democrat wrote.

UnitedHealthcare is the largest provider of Medicare Advantage plans in the U.S. and manages health insurance coverage for employers and state-and federally funded Medicaid programs.
