A 29-year-old restaurant manager has been identified as one of three people killed in the bombing at the Boston Marathon.

Her father says Krystle Campbell, of Medford, Mass., had gone with her best friend to take a picture of the friend's boyfriend crossing the finish line on Monday afternoon.

William Campbell says his daughter, who worked at a restaurant in nearby Arlington, was "very caring, very loving person, and was daddy's little girl." He says the loss has devastated the family.

He says the friend was seriously injured in the explosion.

An 8-year-old, Martin Richard of Boston, also died. He was at the finish line watching the race with his family.

Richard's sister was badly injured and his parents still hospitalized, officials said Tuesday.

Richard was a resident of the Dorchester neighborhood of Boston and a student at St. John Paul II Catholic Academy in Dorchester.

Martin's father, Bill Richard, issued a statement Tuesday afternoon thanking family and friends and asking for continuing prayers.

"My dear son Martin has died from injuries sustained in the attack on Boston. My wife and daughter are both recovering from serious injuries. We thank our family and friends, those we know and those we have never met, for their thoughts and prayers," he said. "I ask that you continue to pray for my family as we remember Martin."

Richard asked for "patience and for privacy" as the family works to "grieve and recover."

U.S. Rep. Stephen Lynch, who represents the area and is a friend of the Richard family, said the Richards' daughter was "grievously wounded."

Lynch, a Democrat first elected in 2001 in a congressional district that stretches from South Boston down past Dorchester, said the parents had worked on his first campaign.

Earlier reports said the father had run Monday, but Lynch said the entire family were observers; the official website of the 117th Boston Marathon does not list the father's name.

The Richard family was hurt by the second of two blasts, Lynch said.

"They heard the first blast. It was very close and it shocked them," Lynch said. "They were in the process of trying to actually get out into the street, away from the buildings, but the barrier, the barrier that was to keep them out of the street was a problem. And, that was when the second bomb went off."

Lynch said he met with several family members at different hospitals late Monday and early Tuesday and that the FBI had interviewed the surviving members of the Richard family -- the parents, another son and a daughter.

Doctors recovered ball bearings from Bill's legs, according to Lynch. The Richards' second son was not physically harmed, he said.

The two bombs were fashioned with pressure cookers and packed with scraps of metal, nails and ball bearings, a person briefed on the investigation told The Associated Press on Tuesday.

In the family's neighborhood Tuesday, resident Rhonda Marques remembered the dead child as "such a sweet little boy. This has devastated not just their family, but the entire city. He was just too young.

"He was a special child," she said. "I'll never forget his smile."

A candle was still burning Wednesday on the steps of the family's home.

Marques and another family friend, Larry Toobin, said that Martin's 5-year-old sister lost a leg and his mother, Denise, suffered a serious brain injury.

"This is unspeakable," Toobin said. "We're all hurting. They're a wonderful family."

At a Tuesday news conference Boston Mayor Thomas Menino said, we grieve for the "tragedy brought to our neighborhood. We grieve for the little boy from Dorchester."

Officials have not released the names of any of those killed in the bombings that occurred in rapid succession as thousands of runners approached the finish line in downtown Boston.

Boston police say their latest tally is three dead, 176 wounded with 17 of those in critical condition.

An FBI source said the death toll could rise to 10 or more because of the severity of many of the injuries.
