Luigi Mangione found with ghost gun, NYPD says of CEO shooting suspect

The person of interest in the shooting death of the UnitedHealthcare CEO in New York was found with a ghost gun capable of shooting a 9 mm and a suppressor.

Police arrested a “strong person of interest” Monday in the brazen Manhattan killing of UnitedHealthcare's CEO after a quick-thinking McDonald’s employee in Pennsylvania alerted authorities to a customer who was found with a weapon and writings linking him to the ambush.

The 26-year-old man had a gun believed to be the one used in the killing and writings suggesting his anger with corporate America, police officials said.

He was taken into custody after police got a tip that he was eating at a McDonald’s in Altoona, Pennsylvania, NYPD Commissioner Jessica Tisch said at a news conference.

He had clothing and a mask similar to those worn by the shooter and a fraudulent New Jersey ID matching one the suspect used to check into a New York City hostel before the shooting, Tisch said.

NYPD Chief of Detectives Joseph Kenny identified the suspect as Luigi Nicholas Mangione, who was born and raised in Maryland, has ties to San Francisco and a last known address in Honolulu, Hawaii. A message left Monday with a Philadelphia-area phone number connected to Mangione was not immediately returned.

Mangione was being held in Pennsylvania on gun charges and will eventually be extradited to New York to face charges in connection with Thompson’s death, Kenny said.

Police found a three-page document with writings suggesting that Mangione had “ill will toward corporate America,” Kenny said.

The handwritten document “speaks to both his motivation and mindset,” Tisch said.
