NEW HAVEN, Conn. (AP) — Connecticut lab officials say blood samples turned up no alcohol or illegal drugs in the two men charged with a gruesome home invasion that left a woman and her two daughters dead.

The lab officials testified Wednesday in New Haven Superior Court in the trial of Joshua Komisarjevsky (koh-mih-sar-JEV'-skee), who faces a possible death sentence if convicted of the 2007 crime in Cheshire.

His co-defendant, Steven Hayes, was convicted last year of strangling Jennifer Hawke-Petit and killing her two daughters, Hayley and Michaela. Hayes was sentenced to death.

Komisarjevsky admits he beat Dr. William Petit with a bat and molested his younger daughter, but he blames Hayes for the three killings. Hayes blamed Komisarjevsky, but prosecutors say both men are equally responsible.
