Search and rescue teams are looking for a missing 23-year-old man who wandered off into a state park.
Justin Dockery was last seen Sunday night when he reportedly had a friend drop him off at Annadel State Park outside Santa Rosa so he could "blow off some steam."
Dockery's sister says he suffers from depression and may have been upset that night. Friends say he was having a good day but was upset all of a sudden by something that happened that day.
He has disappeared before and often goes hiking to clear his head, Dockery's sister told the Santa Rosa Press Democrat. But this is the longest he's ever been gone, she said.
More than 200 people joined Dockery's family and friends Thursday night at a vigil in Santa Rosa.
Dockery does not have his wallet or cell phone with him.
