Amber Hilberling admitted to pushing her husband, an Air Force veteran, out of their 17th-floor apartment in Tulsa during an argument in June 2011.
But she claimed in court she did not intend to kill him, and blamed his fatal fall on “dangerously unsafe” window glass that was too weak to stop his plunge.
Amber, who was seven months pregnant when her husband died, cited self-defense and even rejected a plea deal that would have given her only five years behind bars.
But a jury convicted her of second-degree murder in 2013, after only three hours of deliberation. A judge sentenced her to 25 years in prison.
Amber still stuck by her self-defense claim, repeating it in a televised prison interview with Dr. Phil.
“There was an altercation in which I defended myself,” she told Dr. Phil, adding that her husband flew into a rage after she called him a coward.
She also claimed in the interview that her husband abused her through their 11-month marriage, and she always kept quiet about it.
“I was really good at lying,” Hilberling said.
“That was our relationship: Josh getting in trouble over and over again and me saying, ‘Oh, no, it’s not his fault. That’s my fault. I did that.’
In October 2016, Amber committed suicide in her prison cell.
