CONCORD, N.H. -- A Bay State family that lost a child in a propane explosion in 2003 hopes to prevent other families from experiencing the same, terrible loss.

A Moultonborough, N.H., home was destroyed by the blast, killing 5-year-old Amilia Luhrmann. Her parents were in Concord on Thursday, urging legislators to pass a law to prevent the same mistake from being made again.

The Luhrman family was at the lake house on May 24, 2003, watching a movie. Amilia had gone to bed when a liquid propane leak exploded beneath the house.

"And I kept crying, 'My baby's in there!'" said Amilia's mother, Michelle Luhrmann.

The family, at times overcome with emotion, shared every detail of escaping an inferno without Amilia .

”I feel the pain of my children," said Amilia's grandmother, Margot Luhrmann. "I feel the loss of my grandchild."

A carpenter had unhooked the gas line during some repairs and didn't replace it. Now, the family wants the state to require training and licensing of all who work with fuel lines.

"Some other professions in the state of New Hampshire that have to be licensed are not life-threatening or as dangerous as it is to be working with explosive gas," said Anna Luhrmann, Amilia's sister.

But some in the industry say that the regulation isn't needed.

"We've already been doing certification in our business for the last five years, said Ken Taylor, of the Propane Gas Association of New England.

The state fire marshal who investigated the explosion agreed with the family and wants licensing.

"This'll bring education and accountability to the people doing the work," Fire Marshal William Degnan said.

"Our family will forever miss our dearest Amelia," said Andrew Luhrmann, Amilia's brother. "The only thing that can make it easier is knowing we are trying to prevent this from happening to anyone else."

A House committee is now reviewing Amilia's Law and will vote on the bill within a few weeks.
