The Washington County Sheriff says a 30-year-old Missouri man suspected of killing a deputy is charged with first-degree murder.

Sheriff Andy Skiles said Sunday that Gary Sancegrow of Mineral Point is charged with first-degree murder and armed criminal action in the shooting death of Deputy Christopher Parsons. Parsons, who was 31, was shot and killed when he was responding to an emergency call early Saturday in Mineral Point.

Several law enforcement agencies, including the FBI and U.S. Marshals Service, conducted a daylong search Saturday for Sancegrow, who authorities said fled the scene on foot. Sancegrow was apprehended at a law enforcement checkpoint Saturday evening.

Skiles says Sancegrow is being held without bond at an undisclosed location.
