Could Have Used a Gun

From full article at NY Times:

The men, the authorities say, had already strangled Dr. Petit’s wife, Jennifer Hawke-Petit, 48, and in short order would also kill the couple’s two daughters, Hayley, 17, and Michaela, 11. The elder suspect, Steven J. Hayes, 44, had poured gasoline on the girls and their mother, according to a lawyer and a law enforcement official involved in the case, in hopes of concealing DNA evidence of sexual assault. He had raped Ms. Hawke-Petit, and his partner, Joshua Komisarjevsky, 26, had sexually assaulted Michaela.

Moments after Dr. Petit escaped, as the house was being surrounded by police officers, the men lighted the gasoline. The girls were tied to their beds but alive when the gas Mr. Hayes had spread around the house was set aflame.
