A Wisconsin woman and her son were killed in separate accidents just hours apart.
Police say 45-year-old Mary Moore was hit and killed while she lay prone in the street about 1 a.m. Sunday. The driver fled 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 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.
West Allis Deputy Chief Charles Padgett said Olson knew his mother had been hit, but he wasn't sure if Olson knew she had died. Padgett also 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.
