LOS ANGELES (AP) - Police have charged Michael Jace of "The Shield" with murder, but they still don't know the motive. Police say Jace shot his wife April several times after she got home with their two young sons. They say Jace called 9-1-1 and told a police dispatcher what he'd done. Police are investigating whether financial problems had anything to do with what happened. Jace and his wife had been married nearly eleven years. If convicted, Jace could get 50 years to life.
