When Carpenter was 15 years old, he was hit by a car while skateboarding. He used a wheelchair for several months. It was at this point that he began teaching himself guitar by playing along with the records of bands such as Anthrax, Stormtroopers of Death and Metallica. It has been reported that the driver paid Carpenter a cash settlement that allowed the band to purchase equipment, but drummer Abe Cunningham commented in an interview that this was "a myth about how our band was started."
