Cory Jonell Lumber, a 48-year-old White woman, was found dead inside her Portland apartment in the Mill Park neighborhood on Saturday, July 2, 2016. The medical examiner attributed her death to a single gunshot wound.

That same evening authorities arrested her 37-year-old live-in boyfriend, Spencer Thomas Johnson, and later charged him with murder and unlawful use of a weapon; those charges were designated as domestic violence offenses. Investigators identified a 9mm pistol as the weapon used.

Court records show Johnson had an earlier domestic violence incident about eight months before Lumber’s death: a former girlfriend told police she feared he would eventually kill her and said he had threatened her with a gun. He later pleaded guilty to interfering with a police officer and received 18 months probation that included firearms restrictions and a domestic violence class requirement.

Did anyone who knew Cory or the couple see signs of escalating violence before July 2016?
