MILWAUKEE (WTAQ) - Milwaukee Police are checking to see if a 57-year-old woman suffered a medical problem right before her van slammed into a parked truck.

Christele Williams of Milwaukee died in that crash, which happened Sunday afternoon on the city’s northwest side. The medical examiner’s office identified Williams Monday.

Police said she was going at 35 miles-an-hour before she turned left and hit a truck that was parked at a business docking bay. An 18-month-old child in the vehicle escaped injury, but was taken to a hospital to be checked out.

The medical examiner said Williams was prescribed oxycodone and morphine for chronic back pain – and a daughter said she was acting dizzy lately.
