A 12-hour standoff in Orrington is over and the suspect dead in a police-involved shooting.

State Police confirmed to WLBZ-TV that the confrontation ended just after 2:00 Wednesday morning. Now, the Attorney General's Office will investigate the incident as an officer-involved shooting.

Members of the Penobscot County Sheriff's Office, Bangor, Brewer, and State Police departments swarmed to the Johnson Mill Road in Orrington after a man made serious threats, by phone, to law enforcement. Sheriff Troy Morton said in a press conference that investigators had reason to believe there were firearms in the home. Nearby Center Drive School was put on soft lockdown briefly before police contained the suspect and allowed the children to be sent home.

Several neighbors of the suspect spent the night in a hotel, arranged through the Orrington Fire Department, as law enforcement worked through the night. The standoff lasted more than 12 hours. The man's name and the circumstances behind the shooting have not yet been released.

We'll update this story as more details become available.
