Two West Manheim Township Police officers have been placed on administrative leave after a gunman involved in a standoff at his home was found dead inside Monday night, a state police official said.

The two officers initially went to the 2665 Baltimore Pike home of Brian Anthony Costley to serve a warrant on the 53-year-old man, Trooper Robert Hicks confirmed in a email Tuesday.

But when they attempted to do so, Costley opened fire on them and one officer returned fire, state police had said.

An autopsy preformed Tuesday at Allentown's Lehigh Valley Hospital showed Costley died of a gunshot wound to his torso, according to the York County Coroner's Office.

State police were asked by York County District Attorney Tom Kearney to investigate the circumstances of Costley's death "and the use of lethal force by the West Manheim Police Department," according to a news release issued Tuesday morning.

In York County, it is standard procedure for officers involved in police-related shootings to be placed on administrative leave.

Standoff: Costley, who was outside when the officers arrived about 12:50 p.m., started walking toward his home. Despite being ordered to stop, Costley went inside, then turned around and opened fire on the officers with a handgun, police said.

One officer returned fire while retreating to a safe position, according to police.

Costley barricaded himself inside his home, and the York County Quick Response Team, a SWAT-type unit, was called in, state police said. A second SWAT-style unit from Lancaster County also responded.

When QRT members eventually forced their way into Costley's home hours later, they found him dead inside, police said.

No officers were injured in the standoff.

Costley was wanted in Carroll County, Md., on an outstanding warrant in a DUI case, according to state police.
