YAKIMA, Wash. (AP) – Prosecutors have charged a 33-year-old man with aggravated first-degree murder in the deaths of his mother and sister-in-law.

The Yakima Herald-Republic reports Edward Robinson of Wapato is accused of killing Maria Martinez and Shante Barney on April 9 in the home the women shared.

Yakima County Coroner Jim Curtice says both women were stabbed to death.

Robinson is being held in the Yakima County jail in lieu of $1 million bail.

It wasn’t immediately known if Robinson has a lawyer to comment for him.
