Four years and two murder trials since his family was massacred, Dr. William Petit has finally found happiness with a new love and the uncle of convicted killer Joshua Komisarjevsky has offered his congratulations on their engagement, RadarOnline.com can exclusively reveal.

"Of course, we wish him the very best," Christopher Komisarjevsky told RadarOnline.com in an exclusive interview. "We are happy that he’s found happiness after the tragedy."

Komisarjevsky was found guilty of 17 counts on October 13 for the grisly 2007 murders of Jennifer Hawke-Petit and her daughters, Hayley, 17, and Michaela, 11, and the vicious beating of Dr. Petit in their Cheshire, Connecticut home.

Just when you think the evidence in Joshua Komisarjevsky's death penalty trial for his part in the Petit family murders couldn't get any worse, it took another grisly turn on Wednesday.

Just minutes after the state's chief medical examiner Dr. H. Wayne Carver took the stand to testify, grieving father and husband Dr. William Petit and more than a dozen other distraught family members left the courtroom, reported the Hartford Courant.

As RadarOnline.com has previously reported, Komisarjevsky is charged with 17 counts including murder, abduction and assault in the triple homicide of a mother and her two children, and the beating of their father.
