NEW HAVEN, Conn. (AP) _ Attorneys for a man charged with killing a woman and her two daughters in a brutal home invasion rested their defense with a psychologist saying the man’s history of sexual and drug abuse and concussions increased the likelihood of criminal activity.
Dr. Leo Shea said such a history of drugs and abuse does not mean someone will automatically turn to crime, but makes them more predisposed to criminal behavior.
Under cross examination, Shea acknowledged sexual abuse of children is common.
“It does not necessarily lead to criminal behavior, I would agree with that,” Shea said.
Shea said Komisarjevsky has a narcissistic belief in how smart he is.
“Obviously, he’s very bright in certain ways,” Shea said. “When he is in a new and novel situation, he doesn’t do well.”
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.
Closing arguments are Tuesday.
