Three men are dead and a woman is injured after an apparent murder-suicide in Portland's Centennial neighborhood Sunday night.

The victims and shooter were not immediately identified.

Dozens of police and medical personnel responded to the scene in the vicinity of Southeast Main Street and Southeast 162nd Avenue at around 6:45 p.m. on Dec. 11. According to the Portland Police Bureau, when the officers arrived, they found three men were deceased.

Police said one woman was taken to a hospital for treatment but did not released the severity of the woman's injuries.

A neighbor, who declined to be interviewed on camera, told KOIN 6 that police told her "there was a man that was barricaded in the house that he had shot someone. So that's what the purpose of all of this was."

The heavy police response of at least 32 units included drones and armored police vehicles, plus the SERT and Crisis Negotiation Teams. Police told KOIN 6 News those teams were called in because "they didn't know where the suspect was."

"So, because of that and because of the nature of the call the SERT team and the Crisis Negotiation Team responded to assist in the call," Portland Police Bureau spokesperson Derek Carmon said.

"They're finishing up, there's a crime scene down the street here, and there is no danger to the community at this time. And at this point that's all the information I have to share with you."

By 10 p.m., authorities said they completed the search and cleared the area, but said it was still an active crime scene.
