San Francisco police identified Luigi Mangione, the man accused of killing UnitedHealthcare CEO Brian Thompson, and alerted the FBI four days before his high-profile arrest, according to a new report.
After Thompson was shot and killed last week, an officer recognized the 26-year-old man's face in surveillance images released by the NYPD and tipped off police, officials said. san francisco chronicle.

Police in California knew Mangione's face because his family had reported him missing several weeks earlier, on Nov. 18, the sources added.
When Mangione was finally arrested Monday at a McDonald's in Pennsylvania after a five-day manhunt, authorities said they did not know the identity of the suspected assassin.
It was not immediately clear whether the FBI received or acted on the tip from police.
