NEW HAVEN, Conn. — Flammable liquid was spilled on or around two girls in their bedrooms before they died with their mother in a Connecticut home invasion, a fire investigator testified Friday.

Paul Makuc of the state fire marshal's office testified at the New Haven trial of Steven Hayes, one of two men charged with capital felony murder, sexual assault and other crimes in the 2007 deaths of Jennifer Hawke-Petit and her daughters, 17-year-old Hayley and 11-year-old Michaela. The girls died of smoke inhalation. Their mother was strangled.

Jennifer Hawke-Petit, attended elementary school in Slippery Rock. Her parents, the Rev. Richard and Marybelle Hawke, still live in Slippery Rock.

Prosecutors say Hayes and a co-defendant, Joshua Komisarjevsky, who is still awaiting trial, tied the girls to their beds and poured gasoline on or around them before burning the house.

Makuc described evidence of an accelerant around Michaela's bed and on her body as jurors were shown a photo of the girl.

"The pour pattern of the ignitable liquid went across Michaela's body," Makuc said.

He said a similar pattern of poured liquid was found on the floor of Hayley's room and on her bed as he described distinct and unusual lines of fire leading into the girl's bedrooms from a hallway. During his testimony, jurors were shown a picture of Hayley's charred mattress with rope tied to the bedpost.

A partly melted plastic container was found under Hayley's body in a hallway where she fled.

Jurors were given Monday off, with the trial to resume Tuesday.
