Bostonians have transformed the Boston Marathon finish line area into a memorial for the victims of this month's twin bombings.
Dozens of people gathered at Boylston Street to lay flowers and display messages of hope for the victims.
The memorial includes some of the same guard rails used during the April 15 marathon. Some people tied American flags to the rails and placed dozens of running shoes to show their support. Paper doves tied to nearby trees moved softly in the breeze.
On Friday, the U.S. Marshals Service said Boston Marathon bombing suspect Dzhokhar Tsarnaev was moved to a prison medical facility as authorities continued to search for information about the attack. The bombings killed three people and injured more than 250 others.
Tsarnaev was moved to Federal Medical Center Devens from a Boston hospital, where he had been treated for injuries sustained during his capture last week.
A spokesman did not give details about the condition of the 19-year-old, who officials say is recovering from a neck wound.
Tsarnaev's brother and alleged co-conspirator, 26-year-old Tamerlan Tsarnaev, died in a confrontation with police last week.
Also Friday, FBI agents searched for a laptop computer that is believed to belong to Dzhokar Tsarnaev. Agents in white hazmat suits scoured a landfill near the campus of the University of Massachusetts Dartmouth, where Dzhokar was a student.
In Washington, lawmakers said authorities are trying to determine whether or not the brothers' mother was involved in the radicalization of her two sons. The top Democrat on the House Intelligence Committee, Dutch Ruppersberger, said she is a "person of interest."
The Associated Press reported Friday that the bombing suspects' mother, Zubeidat Tsarnaeva, had been added to a federal terrorism database about 18 months before the Boston attack. She has denied her sons were involvement and has even suggested the bombing could have been staged.
Dzhokhar Tsarnaev faces a charge of using a weapon of mass destruction, which carries a possible death sentence if he is convicted.
New York officials say the suspects were devising a plan to attack Times Square as they were running from authorities. New York Police Chief Ray Kelly says Dzhokhar told investigators they planned to drive to New York to set off their remaining explosives.
He says the plan fell apart when they realized the vehicle they had hijacked was running low on gas. When they stopped to refuel, the driver of the car escaped, and alerted police to their location.
U.S. investigators questioned the suspects' parents in the Russian republic of Dagestan to try to determine if Tamerlan had contacts with Islamic extremists. The family is originally from Chechnya, where Muslim insurgents have for decades been engaged in a bloody conflict with Russia.
