A Connecticut official says a man charged with killing a mother and her daughters during a 2007 home invasion is facing a medical crisis.

Chief state's attorney Kevin Kane says Steven Hayes has "undergone some kind of apparent medical emergency."

A New Haven Register report citing unidentified sources says prison guards found Hayes unconscious in his cell Sunday morning and he was hospitalized in a medically induced coma.

Neither public defender Thomas J. Ullmann nor a University of Connecticut Hospital nursing supervisor would confirm those details.

Ullmann says jury selection scheduled for Monday has been halted.

Hayes and another man have pleaded not guilty in the deaths of Jennifer Hawke-Petit and her daughters, 11-year-old Michaela and 17-year-old Hayley.

Hawke-Petit's husband, Dr. William Petit, was beaten at the Cheshire home but survived.
