Reports from the Hamilton County Medical Examiner say the deaths of three people found in an outbuilding in Hixson on Dec. 2 were due to "fentanyl, methamphetamine and carbon monoxide toxicity."
The deaths were listed as accidental.
The victims were identified as Timothy James Weeks, 47; Elizabeth Consuela Carney, 44, and Joseph Brent Wene, 42.
The reports say a sheriff's deputy was notified by the medical examiner of three deaths that occurred in a 10-foot x 18-foot outbuilding at 1536 Dallas Lake Road.
A family member conducted a well-being check on her father, who was found alive in the outbuilding.
The family member then discovered that two men and a woman were unresponsive inside the small building.
Emergency personnel responded and all three were declared dead.
One of the men was lying on the floor, the other was up against a bed, and the female was lying in bed, the report says.
