NEW HAVEN, Conn. (AP) - A Connecticut jury is deliberating in the trial of a man charged in the home-invasion killings of a woman and her two daughters in 2007.

New Haven Superior Court Judge Jon Blue gave jury instructions Monday morning in the trial of Steven Hayes, who's facing 17 charges, including capital felony, murder and sexual assault.

The 12 jurors heard eight days of testimony about the killings of Jennifer Hawke-Petit and her daughters, 11-year-old Michaela and 17-year-old Hayley, at their Cheshire (CHESH'-ur) home. Hawke-Petit's husband, Dr. William Petit, was beaten but survived.

Hayes and a second suspect who is awaiting trial, Joshua Komisarjevsky (koh-mih-sar-JEFF'-ski), face the possibility of the death penalty if convicted.
