BOSTON (MyFoxBoston.com) -- New video released Friday shows the accused Boston Marathon bombers exercising three days before the attacks.
Splashnews.com posted the never before seen video on their site Friday morning.
The video, which features an April 12 timestamp, shows 19-year-old Dzhokhar Tsarnaev and 26-year-old Tamerlan Tsarnaev jumping rope inside a mixed martial arts gym.
One week later, Dzhokhar was captured after he was found hiding out in a Watertown resident's backyard inside of a boat. His brother died the night before following a shoot out with police. Investigators say Tamerlan was run over by his brother as he tried to flee the scene of the shoot out.
