Authorities say a preliminary autopsy report says a skull fracture killed a man who died in a parking lot in Clive, Iowa.
Clive police say the injury was consistent with a fall to the pavement by 49-year-old Randy Warrens, of Clive. The report says Warrens may have been drinking.
Police say the case is still being investigated, although a crime is not suspected.
Warrens was found around 2 a.m. Saturday when a passer-by spotted him lying in the lot. A witness and, later, emergency medical workers attempted to revive Warrens, but he was pronounced dead at the scene.
