Woman sues husband over death of three sons

An east-central Iowa woman is suing her husband in the deaths of their three sons. The couple’s twin seven-year olds and their ten-year old died when their van went out of control in a snowstorm and ran into a semi. The accident happened in 1998 near Keokuk. Cynthia Rittmer of Mount Vernon says her husband, David, was negligent in his driving and that caused the accident. She’s seeking damages as well as medical costs.
