Matthew Badger's attorney says there's an investigation under way.
One of his main issues is why the burned house was demolished so quickly after the fire.
City officials wanted it down because they said it was unstable, but the attorney says that's inexcusable.
"More importantly, we're going to look at the way that death trap, that fire trap was created and whether there were failures on anybody's part to prevent those kids from dying," attorney Richard Emery said.
The home was under renovations at the time of the fire. The grandparents of the children also died in the home.
The girls' mother and her boyfriend were able to escape.
