Missing teen's autopsy results released - Drugs & Exposure
Autopsy and toxicology results were released Monday for a 19-year-old Petaluma teen whose body was found in a Tahoe area snowbank several days after she was reported missing.
Alyssa Byrne succumbed to probable hypothermia from extended environmental exposure, according to the El Dorado County Sheriff's Office. Other findings included methamphetamine and multiple psychoactive drugs in her system, said Lt. Pete Van Arnum.
Van Arnum declined to specify the other drugs that were found, citing the family's request.
Byrne was reported missing over the New Year's Eve holiday weekend after attending the SnowGlobe Music festival with friends. The last known sighting of her was just before midnight on New Year's Eve.
Officials speculated that Byrne may have tried to walk to the hotel to avoid long shuttle bus lines and became disoriented.
Her body was found Jan. 4 off to the side of Pioneer Trail.
