A cleaning crew reported a female blocking the stairwell in the parking structure. An officer responded and requested medical respond for the female, who was unresponsive. Medical staff arrived and declared her deceased at 0110 hours. There were no obvious signs of foul play. It appeared as though the female had been sleeping under the stairwell. Notifications were made (including the on-call detective) and an ID tech responded along with the San Mateo Coroner's Office.
