CALIFORNIA CITY, Calif. (KERO) — Despite four agencies, including the FBI working the case of the missing California City boys, a licensed private investigator from San Diego is taking his shot at solving the case.

Within his nearly 30 year career as an investigator, Bill Garcia said he's solved more than one-third of the 300 missing persons cases he's been on.

"My team and I do an extremely good job to pick up where law enforcement either does not have the time or same direction as we do," Garcia said. "I do it all because of a 12-year-old Boy Scout that went missing on July 19, 1991, who was not found."

Garcia hopes the same fate isn't apparent for 3-year-old Orson West and 4-year-old Orrin West, the toddler brothers reported missing from their California City home Dec. 21

According to Garcia, his biggest lead in the case comes from a "woman who claims she saw the boys at Albertson's in Tehachapi," on Christmas Eve.

Garcia is now planning a search in certain areas of Tehachapi on Saturday.

But, that's not the direction the investigation has taken authorities.

"I don't know where he's getting his information," California City Police Chief Jon Walker said. "We have several agencies involved. We haven't heard anything about that."

Walker also confirmed that the Tehachapi police have not received such reports.

Garcia also attempted to make contact with the adoptive parents of the missing boys.

"I have reached out to Trezell [adoptive father]," Garcia said.

While Walker said he appreciates the efforts, he also wants Garcia to tread carefully. "He's fully in his right to do that, but as long as he doesn't interfere with our investigation."

Meantime, authorities searched Silver Saddle Ranch for the boys Wednesday.

There was no sign of them.
