New York City Mayor Mayor Eric Adams says police have a 'strong person of interest' in the shooting of UnitedHealthcare CEO Brian Thompson. Police have arrested a 26-year-old man with a weapon consistent with the gun used to kill the head of the largest U.S. health insurer, New York’s police commissioner said Monday. The man was taken into custody after police got a tip that he had been spotted at a McDonald’s in Pennsylvania, NYPD Commissioner Jessica Tisch said at a news conference. “They also recovered clothing, including a mask consistent with those worn by our wanted individual,” Tisch said. “Also recovered was a fraudulent New Jersey ID matching the ID our suspect used to check into his New York City hostel before the shooting incident,” Tisch said. Luigi Nicholas Mangione was taken into custody, Chief of Detectives Joseph Kenny said. Mangione was born and raised in Maryland, has ties to San Francisco and his last known address in Honolulu, Hawaii, Kenny said. The man taken into custody had a ghost gun, a type of weapon that can be assembled at home from parts without a serial number, making them difficult to trace, investigators said. Police found a three-page document with writings suggesting that Mangione had “ill will toward corporate America,” Kenny said. “As of right now the information we’re getting from Altoona is that the gun appears to be a ghost gun that may have been made on a 3D printer, capable of firing a 9 mm round,” Kenny said.
