LIVERMORE FALLS, Maine — A pedestrian was in critical condition at an area hospital after he collided with a Livermore Falls police cruiser late Friday night, according to a news release from the Livermore Falls Police Department.

Joseph Slaver, 24, of Livermore Falls was hit around 11:55 p.m. Friday after he entered Park Street and “struck” the passenger side of a police car driven by Officer Troy Reed, who was heading south, Chief Deputy William Gagne said in an email Saturday evening.

The collision damaged the police car’s front passenger fender, A-pillar and passenger mirror area, Gagne said.

Slaver was transported by ambulance to Central Maine Medical Center in Lewiston, where he was listed in critical condition, according to CBS 13, a Portland-based television station.

The Androscoggin County Sheriff’s Office was leading the investigation into the crash because it involves a member of the Livermore Falls Police Department. A crash reconstructionist from the Lewiston Police Department was assisting the sheriff’s office with the investigation. Crashes involving police cruisers typically are investigated by outside law enforcement agencies.

The crash remained under investigation Saturday.

The Jay Police Department and Livermore Falls Fire Department also provided assistance at the scene.
