A second victim has been identified in the Boston Marathon twin bombings on Tuesday.

29-year-old Krystle M. Campbell from Medford, Mass., was at the race because her boyfriend was running in the annual race. Sadly, Campbell was at the finish line, where the first bomb went off at 2:50pm.

Campbell's father, William A. Campbell, Jr. expressed "shock" at the tragic loss of his daughter.

"My daughter was the most lovable girl. She helped everybody and I'm just so shocked right now. We're just devastated," he told Yahoo News. "She was a wonderful, wonderful girl. Always willing to lend a hand."

Emotional photos were released on Tuesday of Martin Richard, the 8-year-old victim who died while waiting to greet his father at the Boston Marathon.

The Boston Globe reported that Martin, the youngest victim out of the three who have died from the blasts, was with his mother, Denise Martin and six-year-old sister and had stepped off the sidewalk to greet his father Bill Richard- a local community organizer- as he was approaching the tail end of the race. The first bomb that went off at 2:50pm, occurred near the finish line just across the VIP section where families of the victims from the Sandy Hook School shooting were standing.

Richard's mother, Denise Richard, and his 6-year-old sister were critically injured in the blast. Denise underwent surgery for an injury to her brain and Martin's younger sister lost a leg, according to TV station WHDH. Martin was a third-grader who lived with his family in Dorchester, Boston's largest area. Bill is a respected community leader in the Ashmont section of Dorchester.

President Obama addressed the nation during a live televised press conference at 6:10 p.m. on Monday.

"We will find out who did this; we'll find out why they did this," said the president from the White House. "Any responsible individuals, any respon­sible groups will feel the full weight of justice."

Several arrests were made as a federal investigation went underway in the wake of what the FBI has deemed a "an act of terrorism" but no suspects have been named. On Tuesday, an apartment was searched and possible evidence was taken away by federal and local investigators, according to Boston's CBS News.
