Public health officials say 264 people sought treatment at hospitals for injuries sustained in the Boston Marathon bombings.
Three people were killed and at least 14 people lost all or part of a limb. The Boston Public Health Commission says the number includes people who delayed seeking treatment.
For example, some people had ringing in their ears from the blasts and thought it might go away but it persisted for several days.
Other people sought delayed treatment for minor shrapnel wounds and 27 different hospitals treated the injured. There are still 51 people being treated for their injuries in hospitals.
Meanwhile, lawyers for the wife of the deceased bombing suspect say she is doing everything she can to assist authorities.
However, they would not say if Katherine Tsarnaeva, widow of Tamerlan Tsarnaev, has spoken to investigators yet.
Providence attorneys Amato DeLuca and Miriam Weizenbaum issued a statement saying she is deeply mourning the bombing victims.
They say Tsarnaeva and her family were in shock when they learned of allegations against her husband and brother-in-law, Dzhokhar Tsarnaev.
The lawyers say Mrs Tsarnaeva, whose toddler is the daughter of the late suspect, is “trying to come to terms with these events.”
Homeland Security Secretary Janet Napolitano has revealed her agency knew of Tamerlan’s trip to Russia last year, even though his name was misspelled on a travel document.
A key lawmaker had said the misspelling caused the FBI to miss the trip. Napolitano said even though Tsarnaev’s name was misspelled, redundancies in the system allowed his departure to be captured by US authorities in January 2012.
However, she said by the time he came back six months later, an FBI alert on him had expired and so his re-entry was not noted.
“The system pinged when he was leaving the United States.
“By the time he returned, all investigations had been closed,” Napolitano said.
The Russia trip is now seen as potentially important to determining how and when Tamerlan Tsarnaev, the older Boston bomber who died in a firefight with police, apparently became radicalised and whether he had ties to others.
