Some sad news--the industry has lost another star. While some are still reeling from the passing of Arpad Miklos, COLT Studio Group owner John Rutherford has announced on his blog that classic COLT Man Karim has died. The cause is still unknown, but one online source reports that the 52-year-old mountain of muscle died from a "massive heart attack" in his home in Wilton Manors, Florida. Karim appeared in numerous films and photo shoots for COLT and Manifest Men, and the Montreal native was a long-time fitness trainer and bodybuilder who won several titles in the late 1990s. He sometimes worked with real-life partner Brian Cerf. GayDemon sends our sympathy to Karim's family, friends and fans.
