Clackamas County authorities are searching for an armed person of interest in a homicide late Tuesday.

Police are looking for Dean C. Boettcher, 51, of Milwaukie. Investigators are also looking for Paula Rothery, a 44-year-old woman last seen with Boettcher.

Deputies responded to the 17000 block of Southeast Oatfield Road on a report of a disturbance. Police said a man in the home died of "homicidal violence."

Boettcher may be in a 2010 Mini Cooper with the Oregon license plate 399HJK. Police ask anyone who sees the car or Boettcher to call 911 immediately.

Boettcher has a criminal history that includes a 2001 first-degree assault conviction for beating his former boss with a claw hammer. The victim, owner of a Clackamas County furniture store, was seriously injured in the attack. Boettcher was sentenced to 7 1/2 years in prison.

He was also convicted in 2001 of third-degree sex abuse after he inappropriately touched a 16-year-old girl, according to Clackamas County Community Corrections records.

He was released from the Oregon Department of Corrections custody in December 2012, said Betty Bernt, spokeswoman.

Online court records show Boettcher was convicted of fourth-degree assault and attempt to commit a Class A felony. He again caught prison time in June 2012 until March 2015, she said.

Sgt. Brian Jensen, Sheriff's Office spokesman, said Boettcher was a resident of the home along with the victim. He was unsure about Rothery's last known address, and said investigators are sorting through leads.

Jenson could not say how the victim died inside the house.

Southeast Oatfield Road between Southeast Jennings and Southeast McNary reopened at 3 p.m. Wednesday after police processed the scene.

Patrick McDougal has lived two houses to the west of the crime scene. He was sleeping at the time of the homicide.

"My wife was up, and she saw the police come," McDougal said. "She said there were police all over the place."

The neighbor said he did not know the people who lived at the house.

"I know the neighbors on both sides here, but I didn't know the house down there. It's kind of a rental and had more frequent people coming in and out. it seems the people who were living there have changed over the years that we've lived here."

Boettcher is armed and dangerous. DO NOT APPROACH, call 911. pic.twitter.com/no0yAsXE8u — Clackamas Sheriff (@ClackCoSheriff) October 19, 2016
