NEW YORK (AP) — Police say the man charged with killing UnitedHealthcare CEO Brian Thompson was not a client of the medical insurer and may have targeted it because of its size and influence. NYPD Chief of Detectives Joseph Kenny told NBC New York in an interview that investigators have uncovered evidence that Luigi Mangione had prior knowledge UnitedHealthcare was holding its annual investor conference in New York City. Mangione did mention the company in a note found in his possession when he was detained by police in Pennsylvania, where he was arrested Monday after being spotted at a McDonald’s. Mangione remains jailed without bail in Pennsylvania. His lawyer there says he hasn’t seen any evidence yet linking him to the crime.
