The death of BMX star Dave Mirra has led many to wonder if brain trauma like CTE played a role in his suicide Thursday.
Allen Thomas, mayor of Greenville, N.C., and a friend of Mirra, said Friday during a news conference that he thinks there might be a link between Mirra's death and chronic traumatic encephalopathy, which has been tied to repeated concussions in NFL players.
Mirra was a beloved figure in the world of extreme sports, and his name headlined several BMX video games. Until the 2013 X Games in Munich, he held the record for the most medals in history with 24. Of those, 14 were gold medals.
