Autopsies of light heavyweight Justin Levens and his wife Sara McLean-Levens conducted Thursday further suggest a murder-suicide, though the reports have not been deemed conclusive and the case is still pending further investigation.

Levens, 28, and his wife Sara, 25, were found dead Wednesday from gunshot wounds in their home in Laguna Niguel, Calif.

“It was a chest wound that penetrated her heart and killed her and his was to the head,” said Jim Amormino, said O. C. Sheriff Coroner’s Office spokesman Jim Amormino.

Initial evidence suggests Justin Levens was the shooter. Amormino said a handgun had been discovered close to the fighter’s body in the couple’s bed. Sara McLean-Leven’s mother found the bodies together in bed on Wednesday after not hearing from her daughter for five days.

The autopsy reports estimated the time of death occurred approximately four days ago. No suicide note was found at the scene.

Authorities also took into custody what appeared to be prescribed painkillers and anti-depressant medication, though they were not found in the standard-marked pharmaceutical containers denoting whom they belonged to.

A two-time UFC competitor, Levens had tested positive for the painkiller oxymorphone in pre-fight testing for a bout against Ray Lazama at Affliction "Banned" on July 19 at the Honda Center in Anaheim, Calif., according to the California State Athletic Commission. The bout had been cancelled that night due to time constraints.

Toxicology reports of both bodies will take six to eight weeks, said Amormino.

The fire department had been called to the residence twice in the last month, according to Amormino, once for a potential drug overdose and once for smoke coming out of the home.

Amormino was unable to confirm who had overdosed or what the drug was and if anyone had sought out medical care at the time.
