Following the sudden and tragic death of Canadian mixed martial arts trainer Shawn Tompkins on Saturday, it has been learned the famed trainer died of a heart attack. 

CagePotato.com reports that longtime friend and fighter Sam Stout shared his feelings in the London (Ontario) Free Press. 

“I don’t know what to say," Stout said.

"It’s not supposed to be happen to a healthy 37-year-old person. Who would think he had to get checked out for that?"
