This is not the first time a body has been found at a stairway on SF General Hospital property. In 2013, Lynne Spalding was found at a stairway 17 days after missing from her room.
Officials were not acting on a missing person report when the woman's body was found. They do not yet know if she was a missing person or a patient at the hospital.
No further details are available at this time.
Unclear how woman gained access to building. It is not one that is accessible to patients or public. Unknown if this was a hospital patient. pic.twitter.com/h83UjNju97— Melanie Woodrow (@MelanieWoodrow) May 30, 2018
