On Tuesday Jason ‘Mayhem’ Miller, 40, plead guilty to a vandalism charge and was immediately sentenced to 364 days in jail (per CBSLA). Miller has been in jail since August 21 when he was arrested on suspicion of residential burglary and car theft. At that time he was serving probation in connection with a domestic violence case.
Miller’s most recent sentence is the result of a plea deal. That deal saw one count of felony grand theft auto dropped in exchange for his guilty plea on the vandalism charge. Miller, who last fought in 2016, has had numerous run ins with the law in recent years.
In 2019 he plead guilty to felony vandalism and misdemeanour violation of a protective stay-away order. Those charges stemmed from when he punched holes in the walls of his girlfriend’s home in La Habra. He also removed doors from the residence and smashed a large marble table. Miller was sentenced to a year in jail for those charges and three years of probation.
In 2018 Miller was arrested for a probation violation and was discovered to be in possession of a bulletproof vest, various weapons, human growth hormone and other performance enhancing drugs.
In 2017 Miller plead guilty to beating his girlfriend (the same woman whose home he later vandalized). For that he was sentenced to 124 days in jail.
In 2016 Miller was arrested on suspicion of vandalizing a tattoo parlor in Lake Forest. In 2015 he allegedly assaulted a sheriff’s deputy in Mission Viejo. That year he was also arrested in Laguna Beach and charged with simple misdemeanour battery and resisting arrest.
In 2014 Miller live streamed an hours-long standoff with armed police at his home in Mission Viejo. The police were there to arrest Miller on suspicion of domestic violence and stalking. Miller eventually surrendered to police.
In 2013 Miller was arrested twice on suspicion of domestic battery. He was given bail of $100,000. He was later taken into custody for violating a no-contact restraining order.
In 2012 Miller was found naked inside of a church in Mission Viejo. Miller had broken into that building and ransacked it, smashing picture frames and setting off fire extinguishers.
In 2011 Miller was charged with simple assault and false imprisonment after allegedly assaulting his sister at a house party.
Miller’s MMA career began back in 1998. In 2005 he debuted with the UFC, losing to Georges St-Pierre at UFC 52. After appearances for WEC and Dream, Miller signed with Strikeforce in 2009.
In his first Strikeforce bout he lost to Jake Shields for the vacant middleweight championship. His second fight was a win over Tim Stout at Strikeforce Nashville on April 17, 2010. That event is most remembered for the in-cage brawl featuring Miller. That occurred after the main event wrapped up, with Shields defending his title to Dan Henderson. Miller entered the cage during Shield’s post-fight interview. After some shoving a full on brawl broke out between Miller and members of Shields’ team, including Gilbert Melendez, Nick Diaz and Nate Diaz.
Later that year Miller defeated Kazushi Sakuraba at Dream 16. He then signed for the UFC, to coach opposite Michael Bisping in season 14 of The Ultimate Fighter. In that show’s finale Miller lost by TKO to Bisping. He then lost a decision to C.B. Dolloway at UFC 146 in 2012. He was cut from the promotion shortly afterwards.
Miller’s last fight was in 2016—four years after his UFC release—for Italian promotion Venator FC.
