The grand jury convened Tuesday to investigate the death of 26-year-old Adam Wolken, who was found unresponsive in a Gage County Jail cell just before 4 a.m. on Feb. 15. Officials were unable to revive him.
Wolken had been arrested on Feb. 13 following a standoff with police at a Beatrice motel. Police say Wolken held two women and a 20-month old child hostage before surrendering.
State law requires a grand jury investigation whenever a person dies in custody or in the process of being detained.
