The FBI is offering a $10,000 reward to help locate a couple of missing teenagers from Yolo County.
Seventeen-year-old Enrique Rios of Esparto has been missing since mid-October and his friend, 17-year-old Elijah Moore of Woodland, was reported missing in early November.
Investigators say they've exhausted all leads in the case and are hoping somebody can come forward now to help locate the boys.
FBI Spokeswoman Gina Swankie says whether the two boys are together remains a mystery.
"With Enrique and Elijah, they were friends and classmates so we don't know. There's no information telling us where they are, where they may be," says Swankie. "So certainly there is a possibility that they're together, but they also may be apart. Main priority for us right now is getting some information right now that'll help us locate the two."
Tips may be offered anonymously.
The FBI, Yolo County Sheriff and the Woodland Police Department are teaming up to solve the case.
