BRIGHTON (CBS) - Tamerlan Tsarnaev was a very talented boxer, according to friends.
He is believed to have trained at Wai Kru Mixed Martial Arts Gym in the Brighton neighborhood in Boston.
WBZ-TV's Jim Armstrong caught up with Tsarnaev's former trainer Mark Massey on Friday, who describes the man he remembered as a nice guy.
