A library book could end up being used as evidence in Steven Hayes' trial for the murder of three Petit women.
Neither the name of the book nor the subject matter have been released but, according to a report in the Hartford Courant, Hayes was reading the book in the months before the break-in at the Petit family home in Cheshire in July 2007.
A judge brought up the book during a pre-trial hearing on Tuesday. No one connected to the case would discuss the name of the book or reveal its author.
Hayes will be the first suspect to go on trial for the murders of Jennifer Hawke-Petit and her two daughters Hayley, 17, and Michaela, 11.
Hawke-Petit was raped and strangled. Her daughters were tied up and killed when the house was set on fire.
Dr. William Petit Jr., was beaten, but escaped the burning home. Testimony in the Hayes trial is scheduled to start in September.
Another suspect, Joshua Komisarjevsky, will also go on trial early next year. Both men face the death penalty if convicted of the killings.
