Although sheriff's deputies at the hospital did a "perimeter search" of San Francisco General's 24-acre (9.7-hectare) campus within an hour of Spalding's disappearance, it was not until Sept. 30 that they attempted a more extensive search of the grounds, Mirkarimi said.
The next day, after it became clear that not all the stairwells used as fire exits had been searched, a supervisor ordered the stairwell searches to continue, yet "only about half the stairwells" ever were, he said.
Then, on Oct. 4, a hospital staff member told the sheriff's department that someone had reported seeing a body in a locked stairwell of the building where Spalding had been a patient. A sheriff's dispatcher told hospital officials the department would respond, but "there is no indication that any one was dispatched to that stairwell."
