The body of a 44-year-old man was discovered inside a bathroom at the San Francisco Bloomingdale's complex on Friday. Patrick Callahan, who was homeless, "was found in the morning when employees opened the store," according to AP. While the exact cause of death has yet to be revealed, "investigators are also trying to determine if Callahan broke into the store and hid out in the bathroom, or if he was there before the store closed and fell unconscious." A Bloomingdale's spokeswoman described Callahan's death as "very sad."
