A $10,000 reward is offered to help find an attacker who set a Johnson Park gas station attendant on fire, killing him. Secret Witness of Shasta County posted the reward Thursday, a day after the assailant went into the Rocky Ledge Shell, sprayed a flammable liquid on 54-year-old David Wicks and set him on fire. The suspect fled on bicycle and it was found a few blocks away. A tearful co-worker, Kris Cantrell, said that Wicks never had anything bad to say. Cantrell has no idea why anybody would want to hurt him. Deputies do not know why Wicks was targeted. Anyone with information is asked to contact the major crimes unit.
