A woman's body was found in a restroom at a northeast Oklahoma Walmart three days after she was seen on store video entering the room.

Police in the Tulsa suburb of Sand Springs say the body of a 29-year-old was found Monday when the locked bathroom was opened.

According to media reports, a video shows the woman entering the room about 6 p.m. Friday. Store employees assumed because the door was locked that something in the bathroom needed to be fixed, so they placed an out-of-order sign on the door.

A maintenance worker opened the door shortly after 3 p.m. Monday.

The body was sent to the state medical examiner to determine the cause of death, but that it doesn't appear suspicious, reports say.
