The Nebraska Dept of Correctional Services says an inmate died at the state prison in Tecumseh on Sunday.
No cause of death has been given for 47-year old Todd Shade, but prison officials say he was being treated for a long-term medical condition.
Shade had served 25 years of a 100-year sentence for 1st degree sexual assault of a child.
Although foul play is not suspected in Shade’s death, a grand jury will be convened to investigate under a state law that requires a grand jury anytime someone dies in state custody or in the process of being arrested.
