Search efforts for missing Bay Area teacher Ed Cavanaugh ended in tragedy Tuesday.
According to the El Dorado County Sheriff's Department, a family friend aiding in the search found the remains in the Eldorado National Forest, west of Slate Mountain.
The remains were next to a motorbike matching the description of one ridden by Cavanaugh.
Julie Donner, a 25 year resident of the area, says the trails are popular hiking and off-roading, but that even those with experience can run into trouble.
Cavanaugh was a wilderness and survival teacher at San Francisco's Downtown High School.
Family says Cavanaugh left his Georgetown cabin on July 17 on a blue Yamaha motorbike with a friend, but they separated.
Cavanaugh also suffered from diabetes but was diligent about traveling with an adequate supply of insulin and snacks for his trips.
According to the Cavanaugh family blog, hundreds of search and rescue team members from as far away as New York helped with the operation.
The family released the following statement:
“Our family would like to thank every single individual who has worked so hard to bring Ed home. We are overwhelmed with the kindness, generosity and support that has been shown by all in finding Ed. It truly is a testament to Ed’s extraordinary spirit and beautiful soul. Ed has touched so many lives in countless ways. We hope all who love Ed find comfort in knowing that his bright spirit is with us all during this heartbreaking time."
