Loved ones of a Petaluma teen who died in South Lake Tahoe last week will likely wait several more weeks before her remains yield additional clues about what led to her death, a law enforcement official said Wednesday.
A forensic autopsy was conducted Tuesday on Alyssa Byrne, 19, and turned up nothing exceptional that would suggest injury or trauma, according to El Dorado Sheriff's Lt. Pete Van Arnum.
"They did extensive examinations, you know, for everything that could be a possibility, and they haven't found anything suspicious at this point," he said.
But tissue and blood samples taken for testing at an independent lab may furnish information about the role of hypothermia or any alcohol or drugs she might have ingested — though the results will likely not be available for around four weeks, Van Arnum said.
Temperatures in the area dropped to minus 8 degrees Farenheit overnight New Year's Eve and early New Year's Day, which is when Byrne disappeared while attending an outdoor music festival with friends.
