SIOUX CITY, Iowa (AP) – Prosecutors have dropped all charges against an 18-year-old man who was accused of kidnapping and assaulting two men over a dispute about drug dealings. Isaiah Mothershed had been charged with two counts of kidnapping and two counts of willful injury.

Mothershed had been accused of binding and blindfolding two men who met him to buy marijuana on July 7. Court documents had said he burned their faces with a hot object and struck one of them with a shotgun. Authorities said Mothershed had accused them of helping someone steal his marijuana.

The documents said Mothershed forced the men into the trunk of his car, but they escaped when he stopped and left the car to go into a house. Woodbury County Attorney Patrick Jennings, who filed a motion to dismiss the charges Tuesday, said the investigation is ongoing to determine Mothershed’s involvement in the incident.
