BELMONT, N.C. – The toxicology report on a Belmont mother who was missing for several months before her body was found in a car down an embankment concludes the cause of death is "combined toxicity".
Authorities released the toxicology report on 27-year-old Elizabeth "Liz" Stonger to NBC Charlotte on Thursday afternoon.
The toxicology report stated high levels of dextromethorphan and bupropion metabolite could be fatal, coupled with the elevated Sertraline level contributed to the drug toxicity.
Officials say Stonger's body was recovered along with numerous prescription medication bottles, many of which were empty. The empty medication bottles found included Toviaz, Naproxen, promethazine, omeprazole, bupropion and aspirin. Sertraline and Amitiza bottles were also present and each contained several pills, the report stated.
A journal containing a suicide note was also found in the car with Stonger's body.
Authorities said a car was found down the embankment off of U.S. Highway 221 in mid-December containing the body of a white female who authorities positively identified as Stonger.
Stonger's body was found wearing clothes that matched the description of those she was last seen wearing. The vehicle's plates and VIN were identified as belonging to her.
Stonger was last seen in mid-October as she left the WalMart in Belmont on her lunch break. Her sister said she last used her cell phone a minute after clocking out to check her voice mail.
Stonger, a Lowell resident, left behind a 2-year-old son.
