SAN FRANCISCO (KGO) -- The family of a missing San Francisco teacher is offering a $10,000 reward for information leading to his return.
Ed Cavanaugh was last seen July 17 riding a motorcycle with a friend in the El Dorado National Forest.
Cavanaugh's family says he's a "survivalist" but they're worried because he has diabetes and needs medication.
Cavanaugh teaches at Downtown High School, a continuation school in San Francisco.
