Alcohol withdrawal seizures due to chronic alcohol use disorder caused the death of Joanna Ruth Shields in California's Big Sur backcountry, according to the Monterey County Sheriff's Office. The discovery of her body in April initially fueled fears of foul play, but a thorough investigation revealed the tragic truth behind the suspicious marks on her face and neck.

Case Overview: What Happened in Sykes Hot Springs

On a hiking trip in the Ventana Wilderness, 37-year-old Shields was found naked in a pool of water at the Sykes Hot Springs area. Hikers who discovered her also encountered a man who reported hiking with Shields; he said she went to the bathroom and never returned. He later found her facedown in the water. The man cooperated fully with investigators.

The Monterey County Sheriff-Coroner Tina Nieto ruled the cause of death as probable alcohol withdrawal seizures. Autopsy results showed that marks on Shields' neck were insect bites, and a cut on her forehead was superficial. No evidence of crime was found.

Understanding Alcohol Withdrawal and Its Dangers
