Des Moines police says they have identified the vehicle and driver in a hit-and- run and are interviewing him. Police say 19-year-old Samuel Kascoutas of Des Moines was driving a 2002 beige Mitsubishi Montero east bound on Ingersoll Ave when he struck 49-year-old Roberta Schulte also of Des Moines.

Schulte was walking in the travel portion of east bound traffic when she was struck. She is still in critical condition at Iowa Methodist Hospital. It is unclear why she was walking in the roadway as investigators have not been able to speak with her.
