A 22-year-old Spokane Valley man was arrested last week on suspicion of stabbing his aunt in the chest during an argument over child care arrangements.

The man’s mother also was arrested for allegedly striking and obstructing sheriff’s deputies who were attempting to aid the bleeding victim.

The Spokane County Sheriff’s Office said the episode began around 6 p.m. Thursday when deputies responded to a report of a stabbing in an apartment in the 2800 block of North Cherry Street.

Inside, deputies found 48-year-old Gretchen M. Wright and her 45-year-old sister, who was bleeding profusely from the chest. The women told deputies the assailant, Devin R. Dewmer, had fled the scene.

The victim told deputies she had gotten into an argument with Dewmer over his 4-year-old cousin. She said she wanted to take the boy back to her apartment in the same complex, but Fewmer got angry and told the victim to leave, according to court records.

Dewmer then allegedly ran into his room and returned to confront his aunt with a military-style knife, according to court records. She told him, “Now I am for sure taking my grandson while you have a knife in your hand.”

That’s when Dewmer stabbed his aunt in the chest, according to court records.

Wright, Dewmer’s mother, called 911 immediately after the stabbing, but when deputies arrived, she was “extremely agitated and verbally aggressive,” the sheriff’s office said in a statement.

Wright allegedly told deputies they weren’t allowed in her apartment, threatened to sue the sheriff’s office and threatened to “kill cops” if anyone injured her son.

Knowing the victim was inside, Deputy Samuel Turner entered the apartment and found her bleeding from the left side of her chest, according to court records. Turner provided medical aid along with Deputy Joseph Wallace.

Wright continued yelling at the deputies while they tried to deescalate the situation and explain the seriousness of the victim’s condition. According to the sheriff’s office, she called them “evil goons with guns,” “murderous pigs,” and “armed thugs.”

Wright then moved toward the knife but obeyed deputies’ commands to stop, the sheriff’s office said. Then her young grandson entered the room.

While medics took over treating the victim, Wright continued shouting at the deputies from the bathroom of the apartment, and eventually they got between her and the child, according to court records. Wright allegedly responded by hitting a deputy.

One deputy used pepper spray during a brief struggle to arrest Wright. She was booked into the Spokane County Jail on charges of third-degree assault and obstructing an investigation. She was released on her own recognizance on Saturday.

During the confrontation, Dewmer returned to the apartment and admitted to stabbing his aunt, according to court records. He faces a charge of first-degree assault and remained in jail Monday with bond set at $150,000.

The victim was taken to Providence Sacred Heart Medical Center to be treated for her wounds. She was listed in satisfactory condition Monday afternoon.
