An Oklahoma woman convicted of killing her husband after pushing him out a window of their high-rise apartment was found dead in her prison cell Monday.
Guards found Amber Hilberling, 25, unresponsive in her cell around 5:30 p.m. at the Mabel Bassett Correctional Center in McLoud, Oklahoma. She was pronounced dead at the scene, according to the Oklahoma Department of Corrections. A cause of death has not yet been released.
Hilberling was serving a 25-year sentence after being convicted of second-degree murder in 2013 for the death of her husband, Josh Hilberling, an Air Force veteran, who died after falling from a 25th floor window.
Hilberling admitted to pushing her husband, but said she did not intend to kill him. She claimed self-defense, saying the couple was having a fight and she feared for her life. At the time of the incident, she was seven months pregnant with the couple's son.
But prosecutors argued that it was Amber's push that led to Josh's fall from the window.
