Our Brother Jeff Hanneman, May He Rest In Peace (1964 - 2013)
Jeff Hanneman was a guitarist and founding member of Slayer. The thrash metal band was founded in 1981 with guitarist Kerry King and drummer Dave Lombardo in Southern California. They quickly recruited bassist and vocalist Tom Araya. Hanneman had performed with the band until 2011 when he contracted Necrotizing fasciitis, a flesh eating bacteria that he probably got from a spider bite.
