A few questions pertaining to Johnny Lewis' death have been answered -- but the real circumstances surrounding his September death remain a mystery.
The 28-year-old 'Sons of Anarchy' actor died of traumatic injuries sustained in what can only be ruled an accidental fall due to lack of evidence that he jumped or was pushed, according to the official autopsy report released Thursday and obtained by E! News.
Lewis is suspected of killing his landlady before falling to his death from the roof of his residence -- a plunge that, in the opinion of the lead investigator, occurred when he attempted to flee the scene.
"He appears to have jumped from an elevated terrace to the driveway while attempting to flee the scene. During the approximately 15-foot drop he apparently lost his balance or struck an object," wrote investigator Jerry McKibben. "This caused him to land so his head impacted the concrete driveway."
McKibben noted that there was a possibility Lewis was under the influence of drugs or alcohol, but, while he was deemed ineligible for tissue donation due to recent drug use, the autopsy turned up no drugs of any kind in his system.
"Decedent died of a fall," wrote L.A. County Senior Deputy Medical Examiner James K. Ribe. "We do not have definitive evidence that the decedent intended to kill himself. We also do not at this time have any evidence that he was pushed. Therefore, the manner of his death is accidental."
Lewis was cremated and buried at sea off the coast of San Diego last month.
