William Wallace, 30, of Anaheim is expected to be arraigned today in Orange County Superior Court, for the alleged killing of his wife, Zazeli Preston by what authorities say was the result of blunt force trauma. Wallace is being held in the Orange County Jail on $1 million bail and is expected to be in Fullerton Superior Court today for arraignment.

Law enforcement officials say, Preston was killed some tome between Christmas Eve and Christmas Day in their Orange County home. Preston's two young children from a previous relationship as well as the couple's 7 week old baby were inside the apartment when the incident occurred. Wallace called 911 on Christmas Day to make a report of Preston's need for medical attention. When officers arrived at the scene, they found Preston unresponsive in her bed and took her to the hospital where she was later pronounced dead.

Wallace was charged with one count of murder and if convicted, faces 25 years to life in state prison. It is expected that Wallace's Orange County Criminal Defense Attorney will plead not guilty on his behalf at his arraignment.
