Prosecutors in the US have charged actor Michael Jace with murder after his wife was shot and killed in their Los Angeles home.

The 51-year-old actor, who played a police officer in TV crime series The Shield, could face 50 years to life in prison if convicted.

Police claim Jace, who is being held in custody, shot April Jace multiple times in their home earlier this week.

The couple's two young sons were at home at the time of the killing and police have said they are now with relatives.
