A US woman who died in a Walmart bathroom went unnoticed for three days.
Katherine Caraway, 29, is believed to have died of natural causes in the Sand Springs store in Oklahoma.
Employees thought the bathroom was out of order when they found it locked, so they put a sign on it without checking.
When maintenance staff unlocked the door three days later, they discovered Ms Caraway's body.
CCTV footage showed her entering the store on Friday but did not capture her leaving, according to local media.
In a statement, Walmart said it's "saddened" about the discovery.
"We don't know all the facts right now, but we are working closely with local law enforcement to provide what information we have that might be useful."
Investigators are waiting on a medical examiner's report for full details on how Ms Caraway died.
