Paul Matthew Head was 32 when he was last seen at his family’s home in San Luis Obispo on September 9, 1999, before a planned camping trip to the Sierra National Forest. He went into the backcountry near Dinky Creek with an acquaintance; the friend says they drank alcohol and smoked marijuana, then slept in a tent. The friend later woke to find Head behaving oddly, throwing items from the tent and then running into the woods wearing only his underwear and a sweatshirt.

The friend searched briefly, returned to the campsite, and reported Head missing the next day when he did not come back. An intensive search followed — air, ground, and underwater efforts — but no trace of Head was found. Authorities have not ruled out foul play, and his disappearance remains unsolved.

Head worked as a breakfast cook at the Big Sky Cafe in San Luis Obispo and was described as friendly, intelligent, and even-tempered. Does anyone who was in the Sierra National Forest near Dinky Creek in September 1999 or who knew Paul have information that could help explain what happened that night?
