A former boxing coach of Boston Marathon bomber Dzhokhar Tsarnaev's (joh-HAHR' tsahr-NEYE'-ehvz) late brother says Tsarnaev was "like a puppy following his brother."
The defense called John Curran as a witness Tuesday in the sentencing phase of Tsarnaev's trial.
Curran said Tamerlan Tsarnaev had some success as an amateur boxer when he was a teenager. He said Dzhokhar, who was then 10 or 11 years old, came to the gym twice with Tamerlan, and the two brothers appeared to have a close relationship.
A jury is deciding whether Dzhokhar should spend the rest of his life in prison or be executed.
His lawyers have argued that Tamerlan was the mastermind of the bombings and led the then-19-year-old Dzhokhar down the path to terrorism.
A computer expert testifying for the defense in the trial of Boston Marathon bomber Dzhokhar Tsarnaev says his brother Tamerlan's wife did research on her computer to try to find out what the rewards would be for the wife of someone who dies as a martyr fighting in a holy war.
Mark Spencer testified Tuesday that Katherine Russell's computer showed search terms more than a year before the bombings that included: "rewards for wife of mujahedeen" and "if your husband becomes a shahid what are the rewards for you?"
Dzhokhar Tsarnaev's lawyers have argued that Tamerlan Tsarnaev was the mastermind of the bombings and led his younger brother, Dzhokhar, down the path to terrorism. They say Tamerlan became radicalized, and his wife, an American from Rhode Island, also showed signs of becoming a religious fanatic.
