WINTERSET, Iowa (AP) – A Winterset woman has been charged with vehicular homicide following a car crash in May that killed two people. Court records show 21-year-old Mari Silliman faces two counts of vehicular homicide. Des Moines television station KCCI reports she turned herself in earlier this month and is out after posting bond.

The single-vehicle crash in May killed 20-year-old Logan Waltz, of Winterset, and 21-year-old Taylor Aleman, of West Des Moines. Matthew Thomas Lindholm, an attorney for Silliman, says his client plans to plead not guilty to the charges. He says alcohol and drugs were not a factor in the crash, and there will be an investigation into road conditions prior to the crash.
