'Loving' Janitor Found Dead in Department Store Bathroom 4 Days After She Went Missing

The search for a missing South Carolina mother Bessie Durham had a tragic end this week after she was found inside a department store bathroom four days after she died.

The 63-year-old was found dead inside a bathroom at a Belk Department Store in Columbiana Center on Monday, Lexington County Coroner Margaret Fisher said in a statement to PEOPLE. Durham was last seen on surveillance footage entering the bathroom four days earlier.

"The family is heartbroken with the loss of Bessie Durham," her son, Bobby Johnson, wrote on Facebook Thursday. "We are still in shock and asking God to provide peace during this unforeseen circumstance."

"As we grieve our loved one, we ask for your prayers and that you respect our privacy during this time," he continued.

Fisher added that an autopsy on Sept. 22 found that Durham died of natural causes, and the results showed no indication of foul play.

The office will continue to investigate Durham's death along with Columbia Police. The police department did not immediately respond to PEOPLE's request for comment.
