Mixed martial arts lost another one of its own yesterday, as noted trainer Shawn Tompkins passed away at age 37. Details are pretty much nonexistent at this point, and more will be known pending an autopsy. What is known is that through his coaching and expert kickboxing tutelage, Tompkins touched the lives of many - and, in particular, Canadian fighters Mark Hominick, Sam Stout and Chris Horodecki. I never knew him, as he moved outside of my Northeast MMA circles, but the man's impact on the sport was undeniable. Rest in peace, Shawn Tompkins. You will be missed.
