Death Penalty Sought in Boston Marathon Bombing Case

BOSTON (AP) — Federal prosecutors Thursday announced they will seek the death penalty against 20-year-old Dzhokhar Tsarnaev in the Boston Marathon bombing, instantly raising the stakes in what could be one of the most wrenching trials the city has ever seen.

Attorney General Eric Holder's decision to press for Tsarnaev's execution was widely expected. The twin blasts killed three people and wounded more than 260 others, and 17 of the 30 federal charges against him — including using a weapon of mass destruction to kill — carry the possibility of the death penalty.

"The nature of the conduct at issue and the resultant harm compel this decision," Holder said in a statement that consisted of just two terse and dispassionate sentences.

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, including his "betrayal" of the U.S., where he had lived since moving 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 as well as an 8-year-old boy, a "particularly vulnerable" victim because of his age. They also said Tsarnaev committed the killings after "substantial planning and premeditation."

Tsarnaev's lawyers had no immediate comment.

Prosecutors allege Tsarnaev, then 19, and his 26-year-old brother, ethnic Chechens from Russia, built and planted two pressure-cooker bombs near the finish line of the marathon in April to retaliate against the U.S. for its military action in Muslim countries.

The older brother, Tamerlan Tsarnaev, died in a shootout with police during a getaway attempt days after the bombing. Dzhokhar Tsarnaev was wounded but escaped and was later found hiding in a boat parked in a yard in a Boston suburb.

Authorities said he scrawled inside the boat such things as "The US Government is killing our innocent civilians" and "We Muslims are one body, you hurt one you hurt us all."

Killed in the bombings were: Martin Richard, 8, of Boston; Krystle Campbell, 29, of Medford; and Lu Lingzi, 23, a Boston University graduate student from China. At least 16 others lost limbs.

Tsarnaev is also charged in the slaying of the MIT police officer and the carjacking of a motorist during the brothers' getaway attempt.
