New York prosecutors filed a murder charge against the suspect in the killing of UnitedHealthcare's chief executive, a brazen shooting that set off a five-day search that culminated in his capture in Pennsylvania earlier on Monday.

The suspect, identified as Luigi Mangione, 26, was captured in Altoona, Pennsylvania, after he was spotted eating at a McDonald's by a customer and an employee who believed he resembled the gunman, officials said at a news conference.

When approached by two police officers inside the McDonald's and asked if he had recently been in New York, Mangione began to shake and went quiet, one of the responding officers said at a press conference. He had been wearing a mask and sitting alone with a laptop and backpack.
