According to the charges, the victim obtained an order for protection against Evans on Dec. 19, prohibiting him from having contact with her or being at her St. Paul residence. Evans was banned from her apartment for one month on Dec. 1 after causing the victim to be fearful of him. On Dec. 17, he was banned for a year after security had repeatedly documented his return to the property.

The victim told police she got the order for protection because she ran into Evans at a library, where he punched her in the face before fleeing. Later that night, he spray-painted an inappropriate sexual message on the wall outside her apartment and on her door. He also banged on and kicked her door while holding a large knife, the complaint states.

According to the complaint, Evans had been contacting a friend of the woman’s who lives in the apartment building, trying to reach the woman, on Dec. 27. He threatened to slit the woman’s throat and put a bullet in her head.

The next night, St. Paul Police were called to the apartment on the 300 block of North Dale Street on a report that a woman had been stabbed several times in the chest and head. When officers arrived, they found the woman lying on a hallway floor in a pool of blood. Officers traced her blood back to her apartment, where there was blood on the floor and located a knife on the bedroom floor, according to the complaint.

The woman was taken to the hospital with at least three major stab wounds, one to her chest and two to her abdomen. The woman died shortly before 1 a.m. Monday.

The complaint states building security identified Evans leaving the apartment after the woman left her apartment seeking help. Evans was later arrested at the Minneapolis Public Library, wearing the same clothes he had on when he left the woman’s apartment.

Evans told police that he went to the woman’s apartment because she wanted to tell him what was going on with the restraining order. The woman told him she had been having an affair with another man and wanted to call another man so the three could perform sex acts on each other. Evans said he “lost it” because he didn’t know the woman was like that and wanted to marry her. He said he could no longer take watching other people make love to his girlfriend and he snapped, the complaint states.

Evans told police he took a steak knife and stabbed her in the bedroom, but didn’t know how many times. He denied wanting to kill the woman and said he was upset that everything happened at the same time.

An autopsy showed the woman died of a stab wound to the abdomen and her manner of death was a homicide. Evans has two previous convictions, one for murder in 1986 and one for attempted aggravated robbery in 2011.
