LEE -- A Lee man is expected in Central Berkshire District Court for arraignment Friday following a shooting.

No names have been released yet, but authorities say the man shot his stepson three times with an assault rifle around 5:45 p.m. Thursday. A family dog was shot and killed, according to authorities.

The stepson was transported to Berkshire Medical Center on Thursday night. There was no immediate word on his condition.

State Police Lt. Robert Swift says the suspect suffered a medical episode similar to a seizure after the shooting, and also was taken to the hospital. The man was later taken to the Lee State Police Barracks on suspicion of attempted murder.

Thursday evening, state and local police were responded to the shooting incident at 175 Beartown Mountain Road in Lee, according to Pittsfield Lt. Michael Winston.

Police from Lenox, Stockbridge, all of the detectives from the Pittsfield Police Department, members of the Berkshire County Special Response Team and Massachusetts State Police responded, Winston said.

He said that he received a call from Lee Sgt. Jeffrey Roosa, who is a member of the Berkshire County Special Response Team that operates out of the Pittsfield Police Department, for the team's assistance at the scene.

After the alleged shooter was in custody shortly after the call came in, most of the 20 Special Response Team officials that were heading to the scene were called off, but "several continued down there just to help with crime scene stuff going on," Winston said.

Lee Police Department was "tied up" at the scene until well after 9 p.m., according to a dispatcher.

The State Police barracks in Lee, Troop B Community Action Team, the state police detective for Berkshire County District Attorney's Office, and troopers assigned to the Crime Scene Service Section all responded after the Lee Police Department called for assistance, according to Lt. Daniel Richard with Massachusetts State Police.
