MEDFORD, Ore. -- In 1977, Calvin Jay Pringle was reported missing by his mother, after the 17-year-old didn't come back from a trip to California with an older, adult friend: Robert Henry Kellogg.
Investigators note that Kellogg and Pringle became friends after meeting at a bus station in Medford, where Pringle worked bussing tables. Eventually, the two went on a trip that took them to California and Nevada.
But soon afterward, Kellogg came back to Medford alone – saying he last saw Pringle in Los Angeles at a motel. Kellogg added to that, saying he and Pringle had a falling out while they were in California…
Meanwhile, Pringle reportedly disappeared from the motel room.
Case notes also point out that before returning to Medford after their disagreement, Kellogg went to Las Vegas, where he spent Pringle’s money for personal use. However, investigators did mention he had the money to begin with because Pringle’s mother had given it to him – thinking he’d take better care of the funds while on the trip.
Pringle's mother, though, successfully sued Kellogg in small claims court and forced Kellogg to pay restitution.
Kelogg eventually moved to Spokane, Washington, but was still a person of interest in the case.
Though, after failing to show up for a polygraph test on two separate occasions, he wound up leaving the area.
Pringle's body still hasn't been found.
As for Kellogg, a recent investigation found that he died in September 2011. Pringle’s mom, meanwhile, moved around the country and got remarried a couple of times after her son disappeared.
Eventually, investigators say she returned to Oregon, where she passed away in 2006.
