Defense Rests in Connecticut Home Invasion Trial

Attorneys for a Connecticut man charged with killing a woman and her two daughters in a brutal home invasion have finished their defense.

The defense of Joshua Komisarjevsky ended Thursday with a psychologist who said Komisarjevsky told him he was sexually abused as a child and later extensively used drugs. He says medical records showed he had multiple concussions.

Dr. Leo Shea says that history does not mean someone will automatically turn to crime, but makes them more predisposed to criminal behavior.

Komisarjevsky faces a possible death sentence if convicted of the 2007 attack in Cheshire.

His co-defendant, Steven Hayes, was convicted last year of strangling Jennifer Hawke-Petit and killing her daughters, who died of smoke inhalation after the house was set on fire. Hayes is on death row.
