WEST ALLIS, Wis. — A Wisconsin woman and her adult son were killed in separate accidents just hours apart in a Milwaukee suburb.

West Allis police say 45-year-old Mary Moore was struck and killed while lying in the street about 1 a.m. Sunday. The driver that hit Moore fled from the scene.

Then, Moore's 22-year-old son, Thomas Olson, died in a car crash as he rushed to the hospital to see his mother. Olson was a passenger in a car that struck three parked cars and overturned about 5:30 a.m. The driver suffered non-life-threatening injuries and has been arrested on suspicion of drunken driving.

West Allis Deputy Chief Charles Padgett says Moore had been drinking before she was hit, but it's not clear how much. An autopsy was expected to be done Monday.
