Separate Car Accidents Kill Mom, Son Hours Apart Booze apparently a factor in both deaths By Newser Editors and Wire Services Posted May 1, 2012 1:02 PM CDT 5 comments Comments Two tragic accidents in one day. (?vonderauvisuals) (Newser) – A Wisconsin woman and her adult son were killed in separate traffic crashes just hours apart in a Milwaukee suburb, police said yesterday. Mary Moore, 45, died after she was struck by a vehicle; she was apparently hit as she lay prone on a West Allis street. A friend was speeding her son, Thomas Olson, 22, to the hospital to see her when he struck three parked cars and overturned around 5:30am on Sunday, said police. It looks like alcohol was involved in both deaths: Police said Moore had been drinking before she was hit, but it's not clear how much. The driver that hit Moore drove off, but officers later found and arrested the person they believe is responsible. That driver may also have been drinking, authorities said. The driver of the car OIson was riding in was arrested on suspicion of driving while intoxicated. He and two other passengers suffered non-life-threatening injuries. "In my 24 years (of law enforcement), I've seen a lot of strange things, but don't specifically remember a case like this," added the cop.
