MELBOURNE, Florida- A 53-year-old woman’s body was discovered at a Walmart in Melbourne on Friday, which officers say “had been there for quite some time,” according to West Melbourne Police.

Surveillance video at the Walmart shows the woman’s van pulled into the parking lot on Sept. 26, but officials are trying to determine if she stayed there before she died or left and returned later, Florida Today reports.

West Melbourne Police told Florida Today that “there were no obvious signs of trauma” to the body, but it was already decomposing when found.

Detectives are still investigating but so far “have found no signs of foul play,” Florida Today reports.
