Authorities say an intruder in a Missouri home has been shot and killed after assaulting another man.

The Phelps County Sheriff's Office says the shooting happened early Tuesday. The slain man was identified as 39-year-old William Lee Dale, of Rolla. The release says Dale unlawfully entered the home and was shot by a fearful resident after the assault. The coroner pronounced Dale dead at the scene. An autopsy performed Thursday found that he died from a single gunshot wound to the chest.

An investigation into the shooting is ongoing.
