LAPEER, Mich. — A Michigan woman charged with murder in the stabbing death of her adult son who had cerebral palsy is awaiting sentencing after pleading guilty but mentally ill.

Lapeer County Prosecutor Michael Sharkey confirmed to The Flint Journal that Tamara Leonard’s plea was accepted last month ahead of a scheduled jury trial in Lapeer County Circuit Court. Sentencing for the 60-year-old Otter Lake woman is scheduled Feb. 26.

Sheriff’s officials say a 911 call was made in August 2016 from a woman who said she had stabbed herself and someone else. Deputies found Tamara Leonard and 24-year-old Theron Leonard inside the home about 60 miles (97 kilometers) northwest of Detroit.

Theron Leonard was rushed to a hospital, but later died. Tamara Leonard, who was her son’s caregiver, recovered from her wounds.
