A Livermore Falls man who was injured by a police cruiser Friday night remained in critical condition Sunday night at a Lewiston hospital.

Joseph Slaver, 24, was being treated at the intensive care unit of the Central Maine Medical Center Sunday morning.

The Androscoggin County Sheriff’s Office, which is investigating the incident with help from the Lewiston police, initially reported that the police cruiser, which was headed south on Park Street in Livermore Falls, hit Joseph Slaver. Later Saturday, William Gagne, the office’s chief deputy, said in an email that Slaver “struck” the passenger side of the cruiser, damaging the car’s front fender, A-pillar and the area around the mirror on the passenger side.

Attempts to reach Gagne for a further explanation of the incident were unsuccessful.

Crashes involving police cars are usually investigated by police from jurisdictions other than the one involved in the crash.

The Livermore Falls police cruiser was driven by officer Troy Reed.
