A body believed to be that of former UFC middleweight champion Evan Tanner was found in the Palo Verde mountain area, the Imperial Valley Press has reported.

Calls to the Imperial Valley sheriff’s department and coroner’s office were not immediately returned.

Tanner, 37, had embarked on a camping trip some time around Sept. 2 into the desert-like region north of Brawley, Calif., approximately two and a half hours east of San Diego.

Sherdog.com has ascertained various unconfirmed reports that Tanner’s body was identified Monday and that relatives have been notified. An autopsy is said to be scheduled for Tuesday.

Deana Epperson, who grew up across the street from Tanner and his family in his hometown of Amarillo, Texas, said she'd been told that the fighter had texted friends in Oceanside as late as Thursday, telling them that he'd run out of water and gas for his motorcycle. Authorities were then contacted to try and locate the fighter.

Tanner had last been connected to the Compound Mixed Martial Arts & Fitness gym in Oceanside, Calif. Co-owner Claudia Ortega said she and her husband had reached out to Tanner a year ago after he had visited the facility. In recent weeks, Tanner had moved back to the area and visited the gym on a few occasions to train.

Ortega said Tanner told her he planned to “take a couple of trips,” then settle at the gym.

“He wanted to make it his home,” said Ortega. “”We really wanted to see him succeed in any way he could.”

Tanner was a self-made mixed martial arts standout. A two-time state championship wrestler in high school, he made his professional debut on a whim with the Unified Shoot Wrestling Federation in 1997 and defeated three opponents in one night -- including eventual UFC title challenger Paul Buentello  -- in one night to win a heavyweight tournament. He would later defend the title against Pride Fighting Championships and UFC veteran Heath Herring, among others.

He enjoyed his greatest success in the UFC. Tanner won 10 of his first 12 fights with the promotion, losing only to Tito Ortiz and Rich Franklin. His UFC run was highlighted by his upset victory over David Terrell at UFC 51 in February 2005, as he stopped the Brazilian jiu-jitsu black belt on strikes to capture the middleweight championship. Tanner relinquished the 185-pound crown in his rematch with Franklin at UFC 53 four months later, as he absorbed a brutal beating after knocking down the popular Ohioan with a right hand in the first round.

Tanner, the first American to win the Pancrase Neo-Blood tournament in Japan, lost four of his last five fights. He made his final appearance inside the Octagon at “The Ultimate Fighter 7” Finale in June, as he dropped a split decision to Kendall Grove in Las Vegas.

Tanner had recently started his own blog in association with SpikeTV.com.

“I've been sitting around this apartment, bored to tears, waiting on the last of the gear I need for the desert adventure to come in the mail. I've really been looking forward to getting out there,” wrote Tanner. “It seems some MMA websites have reported on the story, posting up that I might die out in the desert, or that it might be my greatest opponent yet, etc. Come on guys. This isn't a version of "Into the Wild". I'm not going out into the desert with a pair of shorts and a bowie knife, to try to live off the land. I'm going fully geared up, and I'm planning on having some fun.”
