Prosecutors: Teen killed Seattle mother after walking away from group home

17-year-old Maple Leaf murder suspect

SEATTLE — A teenager who police say killed his mother on Tuesday did so after telling a staff member at the group home where he was staying that he was going on a short walk, according to court documents.

He is now charged with first-degree domestic violence murder.

Shortly before 8 a.m. on Oct. 13, a 911 dispatcher received a call from the 17-year-old who told them, “I did it. I finally did it,” a transcript of the call said.

When asked what he did, he replied, “I killed my mom,” and “Please send the cops so they can come arrest me,” the transcript said.

When the dispatcher asked how he killed her, he replied, “I bashed her head in and used two knives.”

Probable cause documents said the teen told the dispatcher he was supposed to be at the YouthCare group home and he was supposed to have been on a walk.

Instead, he went to her Maple Leaf home in North Seattle and killed her, charging documents say.

When police arrived at home, the teen was taken into custody.  Once inside the home, officers found the boy’s 45-year-old mother dead with a knife in her chest.

According to the case summary, the teenager had made explicit threats to kill his mother with a kitchen knife as early as June 14.

A check of Seattle Police Department records showed there was a history of domestic violence accusations between the mother and son, and in one incident in June he was arrested for assault after he pushed his mother down, which caused her to break her arm.

In that incident, he told officers that if he was to go home with her, he would kill her with a kitchen knife, a police report said.

Police said that wasn’t the only time he talked about killing his mother.

The teenager, who lived at the YouthCare Pathways residential facility during the week and spent most weekends with his mother, had talked to a staff member about killing his mother only a few days before she was found dead, probable cause documents said.

On Saturday, Oct. 10, the 17-year-old had been staying with his mother when he contacted a Pathways staff member and told him something had happened between him and his mother, and she was going to bring him back, documents said. The staff member said the teen told him he was thinking of killing his mom and later said he was thinking of breaking the window in the car and using the glass to stab his mother to death.

Three days later, she was dead.

The staff member said he counseled the boy against violence, and when the teen arrived back at Pathways, he worked to calm him down tried to help him through his emotions.

The teenager had been in the care of YouthCare since July 31. He was in their emergency shelter and then transitioned to their residential home called Pathways.

Pathways is a shared, non-secured facility for teenagers ages 14 to 17 years old who are having housing difficulties.
