The lawsuit is the first of what’s likely to be several filed against Columbia Gas and its parent company over Thursday’s explosions , which killed one person and injured more than two dozen in Lawrence, Andover and North Andover.

Investigators are working to pinpoint the cause of a series of dramatic natural gas explosions that killed a teenager and left dozens of homes in smoldering ruins in three towns north of Boston.

Police in Massachusetts are currently responding to over 70 reported gas explosions in the communities of Lawrence, Andover and North Andover. At least six people have been injured.
