Mother of man who shot himself after driving into Capitol barrier speaks out

Tamara Cunningham says she believes her son who fatally shot himself struggled with brain trauma from playing football

The mother of a Delaware man who shot himself to death after driving into a US Capitol barricade over the weekend says she believes he was struggling with brain trauma from growing up playing football.

Richard Aaron York III's mother, Tamara Cunningham, said she suspects his past as a high school football player left him with chronic traumatic encephalopathy, a brain condition colloquially known as CTE. Some football players develop CTE because of repeated head blows that are common to the sport.
