Investigators Discover Charred Remains in Missing Teen's Backyard

Adrian Rios and Jose Campos, both 17, have been missing for more than a week.

Nov. 26, 2009 — -- Police in California are working to identify bone fragments found in the backyard of the home of one of two missing teenagers who have not been heard from in more thana week.

Adrian Rios, 17, was last seen Nov. 15 entering the home of Jose Campos, also 17, to watch a football game on TV, Hemet, Calif., Police Lt. Dean Evans told The Associated Press.

The two boys, along with Campos' girlfriend, Felicia Sharp, were reported missing Nov. 17.

Sharp was located Wednesday with her mother, and detectives are now interviewing her.

But the search for Rios and Campos is still on, and with Wednesday's discovery of additional charred bone fragments, investigators are calling their disappearance "suspicious."

The first batch of bones was found in a makeshift grave in the backyard of the Campos family's rented home Nov. 18, authorities said.

At least some of the charred bones indicate that a body had been burned and belong to a single male victim, according to ABC's KABC-TV in Los Angeles.

"We can't really say right now how many, whether it's one or two or three people. That would be pure speculation at this point," Evans told KABC in Los Angeles.

"There is no evidence that these remains are any of these three juveniles. We have no idea who they are at this point," he said

Evans could not be reached Thursday by ABCNews.com for further comment.

Neighbors of Teens Report Foul Smells Coming from Home

Neighbors have reported smelling fumes from what appeared to be a bonfire at the Campos' home on the same night the teens met to watch football.

Matthew Miller, 21, said he saw the boys -- who had bloodshot eyes -- the day they were last seen.

Miller told the AP that the teens had told him that they had been in a fight and claimed that someone had pepper-sprayed them.

Later, Miller and his wife smelled a "foul burning odor."

"It was a horrible, very bad smell," said Miller told KABC.

Miller's wife said that the smell was so bad she had to shut her windows to keep the stench out.

Rios' mother, Elodia Lopez, said that she still believes her son is alive and that he and his friends do not have a history of running away.

"The only thing I know is my son, he never [would] stay and not talk to me for a long time," said Lopez.
