NEW HAVEN, Conn. — A hospital caseworker has testified that the family of a Connecticut man convicted in a deadly home invasion was resistant to medication and professional therapy after he was admitted to a psychiatric hospital as a teen.

Candice Weigle-Spier testified Thursday in the sentencing phase of Joshua Komisarjevsky’s case. He was convicted last month of killing Jennifer Hawke-Petit and her two daughters in Cheshire in 2007, and he faces a possible death sentence.

Weigle-Spier worked at Elmcrest, where Komisarjevsky was sent after his arrest on charges he burned down a vacant gas station.

Hospital records indicate antidepressants and professional treatment were recommended for Komisarjevsky. Weigle-Speir says his parents resisted the idea and chose church counseling instead.

The defense says Komisarjevsky’s religious family failed to get him proper treatment.
