Hartman was last seen in Shreveport, Louisiana, on September 10, 2018. She was in the company of her ex-boyfriend and was last observed leaving the Break n’ Run, a bar on Mansfield Road, with him. In August 2018, another woman, Crystal Beal, went missing. Both women were from Shreveport, had criminal histories, and frequented similar social circles, though police have found no evidence linking their disappearances. Hartman was acquainted with Zachary Hebert, who also went missing in August 2018. His remains were found in a shallow grave in Benson, Louisiana, on October 31, 2018. Due to decomposition, his cause of death was undetermined. The circumstances of Hartman's disappearance are unclear and her case remains unsolved.
