The mother of the man who drove his car into a barricade at the US Capitol, fired a gun into the air and later killed himself as police closed in has said that he was struggling with brain trauma from playing football in his youth.
Tamara Cunningham, the mother of 29-year-old Richard Aaron York III, from Dagsboro, Delaware, told The Guardian that she believes that his high school football career led to him suffering from chronic traumatic encephalopathy (CTE) – a condition some players attain following repeated blows to the head during practices and games.
