BOSTON — Three days before the Boston Marathon bombings, suspects Tamerlan and Dzhokhar Tsarnaev were working out together at a Boston gym. Security cameras captured footage of the brothers arriving at the Wai Kru mixed martial arts center with a friend just before 2:45 p.m. April 12.
The manager at Wai Kru, who wanted to be identified only as Michael, noticed a distinct change in the older brother's appearance. Tamerlan Tsarnaev's full, bushy religious beard, which he had for about two years, was gone.
"Shaving the beard may be a way to blend in, not to attract scrutiny from security services in carrying out the Boston attacks," CNN terror analyst Paul Cruickshank said.
