Search warrant suggests two cars struck West Allis woman

WEST ALLIS -- It was a tragic chain of events -- a West Allis woman was hit and killed while lying in the road. Then, her son died after getting into an accident racing to the hospital to see her. FOX6 News has obtained a search warrant that sheds some light on how this all began.

New information suggests not one, but two different vehicles struck 45-year-old Mary Moore on South 81st Street in West Allis.

Jesse Steinmetz has been charged with killing Moore and claims he thought he hit an animal. However, a search warrant obtained by FOX6 News shows authorities believe they may know why Moore was laying in the road in the first place.

The search warrant says Moore was seeing arguing with 43-year-old Kerry Olson at a nearby bar. Olson is the father of two of Moore's children, including 22-year-old Thomas Olson who died hours after his mother while in a car racing to the hospital after learning about his mother's accident, and believing she was taken to the hospital, injured.

The search warrant says Moore and her ex-boyfriend left Capt'n and Nick's bar together. When police found Olson's car, they found noticable damage to the bumper, white fibers at the damaged area and human hair on the rear driver's side brake light.

FOX6 News has learned Moore and Olson have a violent history that dates back to well before the bar. In 1994, Moore asked for a restraining order against Olson after allegedly being grabbed by both arms and head butted, telling the courts that Olson, in the past, knocked her teeth out.

Moore eventually dropped the restraining order.

Police are now sending evidence to be tested to see if their violent relationship led to a chain of events leaving a mother and son dead.
