An Iowa woman died after being run over by police while sunning on a beach in Oxnard, California. The officers had stopped on a sand berm to watch a swimmer the officers thought was in distress.

When the officers saw the swimmer was fine, they drove over the berm and the woman’s head. The victim was identified as 49-year-old Cindy Conolly of Sioux City. A police commander says the officers did not immediately realize they had run over the woman and continued driving. A witness called for help.

An official with the Ventura County coroner’s office says Conolly was in town for her son’s wedding.
