Reporting from Hemet - The mystery of three missing Hemet teens deepened Wednesday when one turned up alive and well while police unearthed charred human remains at a home where the other two were last seen.

"We have found more human remains, but we can't say if it's one person or two or three," said Lt. Dean Evans of the Hemet Police Department. "It does alarm us that the remains have been found at the home of one of the missing juveniles."

Evans said one of the original three, Felicia Sharpe, was brought to the police station Wednesday by her mother and was being interviewed by investigators.

The youths, all 17, went missing about 10 days ago. The last time friends saw Jose Campos and Adrian Rios was at Campos' rented home on Bluejay Way; they were watching a San Diego Chargers football game.

After the game, neighbors reported a bonfire in the backyard of the home along with a smell so strong that many had to shut their windows.

"It smelled like pallets burning on the beach," said Robert Rotsolk, who lives next door to the Campos home.

Keith McClintock, who lives behind the house, said he recently encountered Rios and Campos running through his yard. He said both had apparently been pepper-sprayed in the eyes and were extremely agitated. He told them to get off his property.

At the urging of Rios' parents, police searched the house Nov. 17 and found burned and fragmented human remains in a grave about 1 1/2 feet deep in the backyard. Additional searches Tuesday and Wednesday turned up more remains.
