U.S. to seek execution of Boston Marathon bomb suspect

BOSTON – Federal prosecutors Thursday announced they will seek the death penalty against 20-year-old Dzhokhar Tsarnaev in the Boston Marathon bombing, accusing him of betraying his adopted country by ruthlessly carrying out a terrorist attack calculated to cause maximum carnage.

U.S. Attorney General Eric Holder’s decision to press for Tsarnaev’s execution was widely expected. The twin blasts last April killed three people and wounded more than 260, and more than half the 30 federal charges against Tsarnaev carry a possible death sentence.

Tsarnaev has pleaded not guilty. No trial date has been set.

In a notice of intent filed in court, federal prosecutors in Boston listed factors they contend justify a sentence of death against Tsarnaev, who moved to the U.S. from Russia about a decade ago.

“Dzhokhar Tsarnaev received asylum from the United States; obtained citizenship and enjoyed the freedoms of a United States citizen; and then betrayed his allegiance to the United States by killing and maiming people in the United States,” read the notice filed by U.S. Attorney Carmen Ortiz.

Prosecutors also cited Tsarnaev’s “lack of remorse” and allegations that he killed an MIT police officer. They also said Tsarnaev committed the killings after “substantial planning and premeditation.”

In addition, they cited his alleged decision to target the Boston Marathon, “an iconic event that draws large crowds of men, women and children to its final stretch, making it especially susceptible to the act and effects of terrorism.”
