William Wallace, 30, is charged with one felony count of murder and faces a maximum sentence of 25 years to life in state prison if convicted, according to the Orange County District Attorney’s Office.
He is being held on $1 million bail and is expected to be arraigned on the indictment Friday.
Prosecutors already have charged Wallace with murder in the death of Zazell Preston, 26, a slaying that happened sometime between Christmas Eve and Christmas morning 2011. An indictment eliminates the need for a preliminary hearing to test the evidence and speeds the case along to a court trial.
Prosecutors accuse Wallace of inflicting blunt-force trauma to the head of his wife, rendering her unconscious.
The victim’s two young children from a previous relationship and the couple’s 7-week-old baby were in the Anaheim apartment at the time of the incident, the D.A.’s Office said. On Christmas morning, Wallace called 911 to report that Preston was in need of medical attention. Anaheim police officers found Preston unresponsive in the bed at the home, prosecutors said.
