Brandon Jacob Spencer Newman made the plea Friday.

He was charged in the October 2019 death of Deborah Onwu at a Wood's Homes assisted living facility in the 1800 block of 27 Avenue S.W., a non-profit mental health centre that provides care for youth and their families.

Newman, who was 18 at the time, was a client at the home.

Investigators said Newman and Onwu got into a verbal and physical argument at which point she was fatally stabbed.

An agreed statement of facts says the woman suffered wounds to her face, neck, chest, thigh and ankle, with at least three wounds to vital organs.

She was stabbed 19 times.

After the killing, the statement says Newman walked away and stashed the knife under a bush about three houses to the east of the facility. DNA matching Newman and Onwu was found on the knife and handle.

Newman's lawyer told the court numerous times during the proceedings his client had a long history of violence, complex mental health issues and was childlike.

A sentencing date is expected to be set next week.
