The decision of the federal Government to seek the death penalty against the man accused of setting off two bombs with his brother in the Boston Marathon last year, killing three people and injuring other 275, was received with support on Thursday for some survivors and their families, but also let others, who continue to recover, in a "loss for words".

Dzhokhar Tsarnaev is awaiting trial on charges that he and his brother, Tamerlane, built and put the pot pressure pumps at the finish line of the Marathon on April 15. Tamerlane died in the subsequent Chase for the pair.

Liz Norden, whose children Paul and J.P. both lost a leg in the bombing, said he made the decision, announced by Attorney General Eric Holder.

"I felt that it was very important that all options are on the table for the members of the jury decide, so I support him," said MSNBC.

But Rebeca Gregory, aged 26, who wounded seriously in the attack along with her son, her boyfriend and her sister, told NBC News that he was a "loss for words" by the decision.

Gregory, of Richmond, Texas, has been struggling to keep his left leg since the attack.

"I don't know how I feel on the matter. We have not tried to participate in it as much as possible because I feel that it has already taken enough of our time as it is. I don't know what is justice in this situation. No matter if you are alive or dead, that changes nothing for us,"he said, adding later:"He will get his trial on the day of the trial, that's what I feel".

Norden said that their children had declined to meet with the Justice Department about the attacks last summer.

"Their sole focus and main focus was in his recovery." They do not feel that you whatever pass is going to change what happened,"she said, noting that"come to terms"with what happened and"later".

"Fully pursue themselves ever better", said. "They are very strong."

Martin Richard, 8, Krystle Campbell, 29 and China national Lu Lingzi, 23, were killed in the attacks. Tsarnaev is also accused of the shooting death of the MIT campus police, Sean Collier, 27 official.

The family of a Richard spokesman said that the family did not want to comment. Messages seeking reaction of several survivors of the left were not immediately returned.

Among the factors listed by the Government in its decision were the killings were intentional, as a result of acts calculated to cause severe risks to public safety and were committed in a cruel manner. And prosecutors said that the defendant has not demonstrated any remorse.

While most legal experts predicted that the Justice Department would seek the death penalty, the decision is expected to be somewhat controversial.

The ACLU of Massachusetts, said was "disappointed" with the decision.

Executive Director of the group, Carol Rose, "The ACLU opposes the death penalty in all cases, because it is discriminatory and arbitrary, and because it inherently violates the constitutional prohibition against cruel and unusual punishment", said in a statement.

"In this case, it is important to note that the people of Massachusetts, through their elected representatives, repeatedly has rejected the death penalty. Even shortly after the Boston Marathon horrible attack, a survey by the Boston Globe found that Boston people said that they would prefer a sentence of life without freedom conditional for Tsarnaev, two-to-one if they condemn him".

A survey conducted in September by the Boston Globe found that 57 percent of respondents favored a sentence of life without parole if Tsarnaev should be condemned, while 33 percent believed that death would be appropriate for the Government to seek punishment.
