It took five days, but the feverish manhunt spurred by the murder of Brian Thompson, the chief executive of UnitedHealthcare who was gunned down in Manhattan on December 4th, has led to a man whom New York’s mayor, Eric Adams, called a “strong person of interest” in the case. On December 9th police arrested 26-year-old Luigi Mangione in Altoona, Pennsylvania, a city of 44,000 people about a five-hour drive from New York. According to Joseph Kenny, the New York Police Department’s chief of detectives, Mr Mangione was found carrying a silencer, a gun and several fake ID cards. Among those was one from New Jersey that had been presented earlier at a New York hostel by a man identified by police as a suspect in Mr Thompson’s killing.
