Although detectives initially thought she may have been sexually assaulted or raped, the chief medical examiner, Dr. William Bogart, said preliminary tests did not bear this out. Results were inconclusive.
Based on three newspaper statements of "A purse (handbag) with her identification was found on the front seat of her car, in a lot adjacent to the stadium", "The purse was left in her car parked near the body" and "The body was found across the college stadium's sunken football field from the women's gym structure", we can create a map of the likely locations within the Diablo Valley College campus.
The journey time from the gymnasium to the parking lot is 90-120 seconds, so either Patricia King was extremely unlucky to have crossed paths with a merciless killer in this short space of time, somebody followed her out of the gymnasium, or somebody, knowing she usually remained in her gym class for just one hour, lay in wait outside. Few leads transpired.
