NEW YORK - The FBI says that it contacted the NYPD over a tip that Luigi Mangione may have been the suspect in the killing of UnitedHealthcare CEO Brian Thompson.
According to the San Francisco Chronicle, a San Francisco police officer contacted the FBI on December 5, the same day surveillance photos of Mangione were released, saying he recognized Mangione's face after his mother reported him missing to the SFPD in November.

The officer said he thought Mangione might be the murder suspect. However, when police arrested Mangione in Pennsylvania four days later, the NYPD said it did not have his name or know who he was until after his arrest.
In a statement to FOX 5, the FBI said, in part: "A tip was received from the San Francisco Police Department regarding the possible identity of the suspect. FBI New York conducted routine investigative activity.... and referred this and other leads to the New York City Police Department as part of our assistance to them in their investigation."
Mangione was arrested Monday at a McDonald’s in Altoona, Pennsylvania, about 230 miles west of New York City.
Mangione may waive extradition from Pennsylvania to New York City as early as Tuesday to face murder charges in the killing of Thompson, according to Manhattan DA Alvin Bragg.
What we know: He is currently fighting extradition and remains jailed without bail.
He was charged with five counts in Pennsylvania: forgery, firearms not to be carried without a license, tampering with records or identification, possessing instruments of crime, and false identification to law enforcement.
His lawyer, Thomas Dickey, said Mangione intends to plead not guilty and has not yet seen evidence definitively linking his client to the crime.
Investigators say Mangione did not have United Health Care
This comes as investigators have revealed that Mangione was not a UnitedHealthcare client but may have targeted the company due to its size and influence.
NYPD Chief of Detectives Joseph Kenny said Mangione mentioned UnitedHealthcare in a note found during his arrest and knew about the company’s annual investor conference in New York City. Kenny added, "We have no indication that he was ever a client of UnitedHealthcare, but he does make mention that it is the fifth largest corporation in America, which would make it the largest healthcare organization in America. So that’s possibly why he targeted that company."
