An 80-year-old Wyoming inmate who was convicted of murder nearly 40 years after her husband went missing has died.

The Wyoming Department of Corrections says Alice Uden died Wednesday from chronic health issues at a hospital in Scottsbluff, Nebraska.

Uden had been incarcerated at the Wyoming Medium Correctional Institution in Torrington.

Uden was convicted of second-degree murder in 2014 for killing Ronald Holtz in the mid-1970s in Cheyenne and throwing his body down an abandoned gold mine shaft. His body wasn't found until 2013.

In addition, Uden's husband, Gerald Uden, pleaded guilty in 2013 to killing his ex-wife and two of her children in 1980 in a separate Wyoming case. He also was sentenced to life in prison. The Udens were arrested in Missouri where they had been living.
