She said he went to Los Angeles where he went partying, and as of now, said his disappearance appears to be voluntary missing. Jones was also reportedly mugged and assaulted during the trip to California while outside of The Plaza Club, and was left with a concussion before he was sent to Cedars-Sinai Medical Center for treatment, according to KTLA. McMahon told Daily Mail Online Jones was in a fight at the nightclub which took place on Friday, April 3. She said there are limited details available regarding that incident and his time at the hospital. His family believes he checked himself out of the hospital. 'We're thinking that his concussion really affected his ability to reason or be able to do anything,' Jones' older brother Jared Jones told ABC 7. Jared Jones also said his cousin Travis, who investigators plan to speak to on Friday, was traveling from Los Angeles to Las Vegas when he and a friend picked Jones up on April 4. He said they then stopped at restaurant Claim Jumper in Rancho Cucamonga, according to NBC Los Angeles. His family has posted fliers near the Walmart hoping to find a lead (above investigators searching a vineyard for any traces of Jones on Thursday) A private investigator learned a homeless man said he spoke to Jones outside of the Walmart, and he was interviewed by San Bernardino County Sheriff's deputies (above).

However, private investigator Paul Huebl, suspected foul play. 'He [Jones] bought some stuff and apparently a transient wound up with some of the stuff,' Huebl told ABC 7.
