According to officers, around 10:30 a.m., a mother and daughter were getting ready to leave their home for church when an unknown man approached and tried grabbing one of them.

The mother and daughter then went back inside their home, but the suspect "forced his way inside," according to police.

The 55-year-old mother then retrieved a gun and fired two shots at the suspect, hitting him at least once in the chest. Medics pronounced him dead at the scene.

Police say the shooting was in self-defense and no arrests will be made.
