Police identify man killed in domestic disturbance
Stabbing death reported Thursday morning at a residence on Southeast 158th Avenue
Police have identified the man killed in a domestic violence-related stabbing on Southeast 158th Avenue on Thursday as Matthew Leon Deming, 38.
Police say Deming's former girlfriend, Misty Dawn Keeney, 39, has cooperated with investigators and has not been arrested in this case.
Homicide detectives are continuing to investigate the circumstances of the stabbing. Once the investigation is complete, the case will be presented to the Multnomah County District Attorney's Office for review.
According to police, at 8:17 a.m. May 14, East Precinct officers received a call of a disturbance in the 3200 block of Southeast 158th Avenue. Initial reports indicated that the call may have involved domestic violence.
The man identified as Deming allegedly broke into his former girlfriend Misty Dawn Keeney's house on Southeast 158th Avenue. Keeney then stabbed him, Portland Police Sgt. Greg Stewart said at an impromptu press conference near the scene of the homicide.
After he was stabbed, Deming fled on foot, got into his car, which was parked several blocks away, and drove off before crashing at the intersection of Southeast 162nd Avenue and Division Street.
Witnesses called the police to the crash scene, and officers quickly realized those calls were related to the disturbance.
Deming was then transported to an area hospital with life-threatening injuries and died at the hospital.
They did not say if Keeney had been injured and did not know if she had a restraining order in place. She is not in custody and is cooperating with police, Stewart said.
