HARTFORD, Conn. — One of two men convicted in the killings of a mother and her two daughters in a 2007 Connecticut home invasion is seeking a new trial, saying recordings of non-emergency police phone lines were withheld from the defense.

Lawyers for Joshua Komisarjevsky asked the Connecticut Supreme Court last week to hold an evidentiary hearing, reverse Komisarjevsky’s convictions and order a new trial.

The lawyers say the recordings would have proved a defense theory that the police response to the Cheshire home invasion was inadequate — an effort to question the credibility of police witnesses.

Komisarjevsky and Steven Hayes are on death row for the killings of Jennifer Hawke-Petit and her daughters, 17-year-old Hayley and 11-year-old Michaela.

Hawke-Petit spent her elementary school years in Slippery Rock. Her parents, the Rev. Richard and Marybelle Hawke, still live in Slippery Rock.

Prosecutors say the recordings were given to the defense and don’t raise any significant appeal issues.
