“During routine sparring, tempers flared between Charles and the other fighter, and Charles ended up getting dropped by the larger training partner,” wrote Vaughn. “They were quickly broken up and Charles left the mat, got dressed and left the building. He returned about 15 minutes later, walked down to the training area and pulled out a heavy piece of steel he must have found in the parking lot and began attacking the other fighter (from behind) with intent to do serious damage. He was tackled by two other fighters and disarmed.
