DUBUQUE, Iowa (AP) — Jail authorities used a stun gun on a Dubuque man charged with murder after he refused to obey commands. Court documents say 22-year-old Helmon Betwell violated jail rules Sunday and received multiple verbal commands before Dubuque County Sheriff’s Department deputies used a stun gun to obtain compliance.

The Telegraph Herald reports Betwell has been charged with interference with official acts in relation to the incident. He also has been charged with murder, sexual assault and burglary connected to a fatal attack on a 66-year-old woman on Sept. 1, 2015, as she was walking in Dubuque. The trial was moved out of Dubuque County after extensive media coverage. Betwell’s trial had been set for May, but the prosecution and defense both said Friday they need more time to prepare.
