The show, which will be broadcast Monday, March 1, at 3 p.m., will give the family a chance to tell their story, Heath Carey said in a telephone interview.

     Producers for the show first approached the family several months ago, after finding a Web site, www.flowersareforever.org, the couple created in memory of their daughters.

     The couple traveled to New York for the taping in January. Even two years after the tragedy, Heath Carey said, the wound is still raw.

     "It's pretty difficult," he said. "I don't think we really understood everything it would be, but it got pretty emotional when we were there."

     Violet Carey, 5 1/2, and 4-year-old Iris Carey, died July 24, 2002, when a natural gas explosion leveled their apartment building in downtown Hopkinton. The building's other residents, including Tara and Heath, escaped with minor injuries.
     Though no clear cause has been identified for the blast, in a report released last year, the state Department of Telecommunications and Energy suggested gas company NStar may have violated state and federal regulations by not properly inspecting and maintaining gas lines.

     According to the report, there were no records showing the building's gas lines had been properly tested.

     An official cause for the blast, however, hasn't been determined, and the family continues to press forward with suits against NStar, their landlord and Holden-based pipe fitting manufacturer Inner-Tite Corp., which manufactured the crucial fitting.

     There have been some bright spots in recent months, though.

     After Heath Carey underwent surgery to reverse a vasectomy, Tara Carey last year announced she was pregnant. Five months ago, Heath said, the couple welcomed their first boy -- named Lexington -- into the world.
