Luigi Mangione’s mother filed November missing person report; 26-year-old charged after UnitedHealthcare CEO shot, killed in NYC [Video]

NEW YORK — Luigi Mangione’s mother filed a missing persons report about her son in San Francisco on Nov. 18 — 16 days before he allegedly shot dead UnitedHealthcare CEO Brian Thompson in New York City — law enforcement sources told ABC News.

Mangione appeared in court in Pennsylvania on Monday, shortly after his arrest at a McDonald’s restaurant in Altoona, Pennsylvania, following a five-day manhunt across multiple states. Mangione told a judge he was in touch with his family “until recently.”

Law enforcement sources told ABC News that Mangione’s mother spoke with a task force of FBI agents and New York Police Department detectives one day before her son’s arrest on Dec. 9.

That conversation followed a tip the FBI received from the police in San Francisco, where Mangione’s mother filed the missing persons report.
