LINCOLN, Neb. (AP) — A grand jury has found no wrongdoing in the August death of an inmate who collapsed while playing basketball.

The Lincoln Journal Star reports that the grand jury report says 35-year-old Lucius Turner died last year at the Nebraska State Penitentiary in Lincoln as a result of an abnormal heartbeat due to heart disease.

A criminal investigator with the Nebraska State Patrol testified that Turner had just made a jump shot, high-fived another inmate, and then collapsed as he went to sit down.

Staff called 911, began CPR and used a defibrillator before medics took over. Turner was later pronounced dead.

Turner was serving a sentence of 40-55 years for robberies in Gage and Lancaster counties.

State law requires a grand jury investigation whenever someone dies in custody.
