NEW YORK—After days of searching through security footage, following up on a deluge of tips and even sending scuba divers to the bottom of a lake, police on Monday announced the arrest of a suspect in the killing of UnitedHealthcare’s CEO outside a Midtown Manhattan hotel last week.
The hunt began in the hours after Brian Thompson was gunned down on the sidewalk early Wednesday morning, with the suspected shooter slipping away from the scene and riding a bike to Central Park, before taking a taxi to a bus depot that offers service to several nearby states.
