Goings, 40, was convicted after just four hours of jury deliberations in February 2013.
Goings shot and killed Henry in her South Loop condo on January 24, 2009 as she ran with her daughter, Ava. Ava's father is former Chicago Bulls player Eddy Curry. Henry and Curry's other son with Nova, Noah, 3, was home during the shooting, but unharmed. Nova and Ava were buried days after their bodies were found. Goings was charged almost a month after their murders.
Goings and Henry became romantically involved when he represented her in a paternity case with Curry. Prosecutors say their relationship took a nasty turn when Henry hired a new lawyer and planned to contest his legal fees.
"Domestic violence was the route of this evil act committed by Fredrick Goings," said Yolan Henry after Goings' February conviction. "No one should live in fear of their life, ever. Nova was afraid. Nova was afraid for her life and her family's lives, so if we you know someone, or if it is you that is involved in a domestic violence situation, listen to that voice that tells you to leave."
During the trial, Goings maintained his innocence and argued that no physical evidence linked him to the murders.
He faces natural life in prison.
