Jeffery was born on September 21, 1964, to Frank and Christine Thompson. He was the older brother to triplets Seth, Micah and Martin. During his 40 years on this earth, Mayhem became a master of building and repairing all things mechanical. A true Renaissance man, he was also a live actor at the Scarborough and Texas Renaissance Festivals, and a television actor for Ruffles Potato Chips and 7-11 commercials. He even appeared as a supporting actor on the hit series Walker Texas Ranger. He was a radio shock jock sidekick for KEGL, a musician, a Dallas club bouncer, a personal bodyguard for celebrities and rock-n-roll royalty, and head of security for the heavy metal band Damageplan.

More than all of his professional titles combined, Mayhem was an extremely dedicated and loyal friend—the kind of friend whom death itself could not intimidate! Sadly, on December 8, 2004, while on the road in Columbus, Ohio with long-time friends Dimebag Darrell and Vinnie Paul Abbott and the rest of the Damageplan crew, Mayhem’s life was taken away from us when a crazed gunman ran onto stage, senselessly attacking and killing guitarist Darrell Abbott. Mayhem was on the attacker in less than a second. Regardless of the 4 shots which were already fired, he was committed to protecting his friends and the audience from the armed killer. During the struggle, the killer fired two fatal shots at point blank range. Jeffery "Mayhem" Thompson died a hero, placing the safety of others ahead of himself. He fell with two other heroes—audience member Nathan Bray and venue security member Erin Halk, who bravely took to the stage to give assistance and subdue the killer. The rampage finally ended when first responding police officer James Niggemeyer shot and killed the attacker.

Now we pay tribute to Jeffery "Mayhem" Thompson, celebrating both his life and the lives of Darrell Abbott, Nathan Bray, and Erin Halk.
