Police investigators in Sand Springs, Oklahoma are baffled as to what happened to a woman who they say walked into a Walmart and was later found dead. Officers are currently investigating the death of a 29-year-old woman whose body was found inside the Sand Springs Walmart bathroom three days after she entered the store. Sources said that a Walmart employee discovered the body of Katherine Caraway, who is originally from Texas, on Monday afternoon during a restroom inspection.

According to a story in the Associated Press, police said her death is currently under investigation, but while the cause is still unclear, it does not appear to be related to foul play. Officers also said they are not sure just when Ms. Caraway died and will depend on a determination from medical examiners for that information. Walmart employee said they thought the bathroom Caraway occupied was “out of order,” so they put up a sign that remained there until her body was discovered by another employee.

Following the discovery of the Ms. Caraway’s body, Walmart issued the following statement:

“We are saddened by this. 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. Because this is an ongoing investigation, we must refer you to them for additional information.”

Speaking on a condition that he remained unnamed, a police officer told the Sand Springs Leader there is a lot they don’t yet know about the incident. They aren’t sure what Caraway, who lived in Muskogee, Oklahoma, was doing in Sand Springs. Muskogee is located about an hours drive from Sand Springs. Even getting a positive identification on the woman was not easy as Caraway’s family had to make a trip from Texas to identify the body. According to Caraway’s Facebook, she is from Celeste, Texas, a small town 60 miles outside of Dallas. She is survived by her young son.
