San Diego police are under close scrutiny after accidentally shooting a homeowner who called 911 after allegedly seeing a man in a ski mask prowling the neighborhood.

While searching for the man, police entered the backyard of the woman’s home, San Diego County sheriff’s homicide Lt. Larry Nesbit explained. There, they made contact with the homeowner and, horrifyingly, shot her.
