A New York jury convicted Narcy Novack on Wednesday of murder and other charges in the killing of her millionaire Fountainebleu Hotel heir husband and his mother.
Her brother, Cristobal Veliz, also was found guilty of the same charges: murder, racketeering, domestic violence, stalking, money laundering and witness tampering.
The convictions in the White Plains court relate to July 2009's brutal Fort Lauderdale, Fla., killings
of Ben Novack Jr. and is mother Bernice by two hit men hired by the brother and sister. The killers later confessed.
Narcy, a former stripper from Ecuador, was accused of being motivated by jealousy after finding out her husband was having an affair. Fearing he'd divorce her and leave her broke, she killed him
in hopes of gaining the millions from his will, prosecutors alleged.
Narcy and her brother both face up to life in prison at their sentencing Nov. 1.
