A Boston PR and public affairs firm is aiding the family of eight-year-old Martin Richard, who was killed in the April 15 bombings at the Boston Marathon.

Martin RichardLiberty Square Group is speaking for the well-respected Richard family of Dorchester, Mass.

"We are helping them out," confirmed Conor Yunits, a senior VP at LSG who is a former director of communications for the Greater Boston Chamber of Commerce and founded the political site MassBeacon.com.

Photos of Martin Richard released by his family have been widely circulated, as the boy was the first victim identified in the double bombing. Martin's seven-year-old sister, Jane, suffered a serious leg injury, while their mother, Denise, was also severely injured. Father Bill Richard's leg was penetrated by ball bearings from the blast.

Bill Richard released this statement April 26:

"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. I ask that you continue to pray for my family as we remember Martin. We also ask for your patience and for privacy as we work to simultaneously grieve and recover."

The bombs Monday have claimed three lives. In addition to Martin Richard, 29-year-old Krystle Campbell was identified as a second victim. Her family held a somber press conference Tuesday outside their Medford, Mass., home.

The third victim was identified this morning as a Boston University graduate student from China, Lu Lingzi.
