Khaos Williams

Kalinn "Khaos" Williams

In July 2013, Williams became the first graduate of a cooperative online education program between the Jackson County Sheriff's Office and Jackson Public Schools. Williams earned a high school diploma through an online program while incarcerated in Jackson County Jail after being convicted of selling cocaine. He's had a spotless probation record and has performed all his required community service.

He started training in September 2013 and had his first fight three months later. His interest in MMA started because someone saw him fight and told him that he had it. So afterwards, he found a BJJ gym and fell in love after his first bout. He started training with Leo Aponte, his former Jackson High School teacher and current mixed martial arts coach.
