The Catoosa County sheriff says he believes Brandi Elliott may have died of a drug overdose.

Elliott's body was found on McGill Lane on August 17.

Sheriff Gary Sisk says Elliott's toxicology report has not come back yet so it’s not clear what exactly led to her death, but he says his team has talked to several people connected to Elliott who say heroin and fentanyl could be to blame.

“We did a number of interviews yesterday all through Tennessee just trying to get everyone's story trying to again pinpoint and plot out her last 24, 48 hours of life,” he said. “So far everyone that we've talked to is all associated in the Birchwood..Ooltewah area. Nothing besides just this is where she was found is tying her to north Georgia right now.”

The 38-year-old, who deputies say was wearing a black tank top and blue jeans, was a daughter, a friend and a mother of two, according to her Facebook profile. Sheriff Sisk says Elliott had finished serving time at Silverdale detention center just days before she died.

“Unfortunately the family did report that she had been struggling with a drug addiction,” Sisk said. “If that is what it is and it's going to be an overdose then she went right back into the lifestyle at her choosing.”

This is the second deadly case the sheriff’s office has investigated within three months that has been drug-related. Sheriff Sisk says these cases are difficult for everyone involved. 

“We gotta keep fighting for our loved ones but they're adults and they're making decisions and again we can’t force them to get the help,” he said. “It is gut-wrenching.”

Sheriff Sisk says they will continue to follow leads and search for more answers.
