Anyone have predictions for the penalty phase of the Boston Marathon bombing trial?

As highlighted by this new AP article, headlined "Bombing trial enters penalty phase amid life or death debate,"the real legal intrigue surrounding the capital trial of the Boston Marathon bombing is about to begin:

The guilt phase of Boston Marathon bomber Dzhokhar Tsarnaev's trial was considered a slam dunk for prosecutors, especially after his lawyers bluntly admitted during opening statements that he participated in the deadly 2013 attack. But the outcome of the next phase of the trial is much more difficult to predict. The same jury must decide whether Tsarnaev, 21, should be put to death or spend the rest of his life in prison. The penalty phase begins Tuesday in U.S. District Court.

Debate over whether Tsarnaev should get the death penalty intensified recently after the parents of Martin Richard, an 8-year-old boy who was killed in the bombings, urged federal authorities to consider taking death off the table in exchange for Tsarnaev spending the rest of his life in prison and giving up his rights to appeal....

A married couple who lost limbs in the attack also asked the U.S. Justice Department not to pursue the death penalty. "If there is anyone who deserves the ultimate punishment, it is the defendant. However, we must overcome the impulse for vengeance," Jessica Kensky and Patrick Downes said in a statement to the Globe Sunday....

Others have said they favor the death penalty for Tsarnaev. Liz Norden, whose two adult sons each lost a leg in the bombings, said nothing short of execution is warranted. "He destroyed so many families that day," she said. "I want the ultimate justice."

Legal experts differ on whether the pleas from victims will persuade the federal government to drop its bid for the death penalty. "If the Justice Department seriously takes into consideration the feelings of the family members in this case, they have every justification to take death off the table," said Robert Dunham, executive director of the Death Penalty Information Center.

But New York Law School professor Robert Blecker said the Justice Department has to consider the larger question of denouncing terrorism. "They'll go forward with it. It will not change the decision. Denunciation is a legitimate purpose," Blecker said....

During the penalty phase, the defense will continue to portray Tsarnaev's brother, Tamerlan, 26, as a domineering follower of radical Islam who convinced his then 19-year-old brother that America had to be punished for its wars in Muslim countries. Tamerlan died four days after the bombings when he was shot during a firefight with police and run over by Dzhokhar during a getaway attempt.

Prosecutors are expected to emphasize the brutality of the bombings by calling more survivors to testify. During the first phase, several survivors testified about devastating injuries, including lost limbs....

If even one juror votes against the death penalty, Tsarnaev will get a life sentence.
