Updated at 1:41 p.m.: Police have identified the victim in Saturday's homicide as Cory Jonell Lumber, 48. She died of a single gunshot wound.

A 2015 police report about Spencer Thomas Johnson, the man charged with murder in the death of his girlfriend in Portland Saturday, contains a chilling prediction from his girlfriend:

"She feels that he is eventually going to kill," a prosecutor wrote eight months ago.

A Portland police officer gave prosecutors that account after an out-of-state relative of Johnson's then-girlfriend asked police to check on her. That girlfriend, a 43-year-old woman, is not the woman Johnson is charged with murdering, said Portland police spokesman Pete Simpson.

Two officers came to the 43-year-old woman's home on a Wednesday evening last October to check on her. They said she appeared calm and collected and allowed them in, a court record says.

But then things took a frightening turn, the probable cause report says. The woman's face contorted with fear as she watched Johnson, then 36, walk toward her with a handgun in his right hand. Both officers who were there, Gedemynas Jakubauskas and John Macaulay, drew their pistols and ordered Johnson to put down his gun.

But, they reported, Johnson continued to walk toward the woman and was fixated only on her. He stood five feet from her, gun in hand, and said, 'You called the cops... I can't believe you called the cops," the court document says.

Both officers again told him to put down his gun, but he ignored them. Jakubaukas said he was prepared to shoot Johnson if the man were to raise the gun toward his girlfriend, the report says. Johnson continued to ignore the two police officers in the kitchen as they repeatedly told him to put down his gun.

Eventually, he did turn over the gun and was handcuffed and taken to jail. The gun was a 9 mm pistol and was loaded, the report says.

Johnson remained calm throughout the entire incident and told police he did not immediately hand over his gun because he was unsure who the officers were and was trying to protect his girlfriend from intruders, the report says. He told officers he had a second gun in the bedroom plus about 30 other weapons, including AR-15 rifles, at other locations. The officers took the second gun away from him too, the report says.

The 43-year-old woman told Macaulay she was frightened of Johnson and that he had repeatedly threatened to shoot her and had hurt her with his hands. "She feels that he is eventually going to kill her," the report says.

Johnson was charged with two counts of interfering with a police officer, attempted assault and harassment, court records show. In April of this year, he pleaded guilty to one count of interfering with a police officer, a misdemeanor.

Multnomah County Judge Cheryl Albrecht sentenced him to 18 months of probation with conditions including a prohibition on drinking alcohol and possessing guns or other weapons. His plea agreement also required him to take a domestic violence course and perform 40 hours of community service.

On Saturday, Johnson was charged with murder in the death of his 48-year-old girlfriend, Cory Lumber, in Southeast Portland.
