A Tyndall man and a Rapid City woman have been indicted by a federal grand jury for possession of an unregistered firearm.

Jose Edwardo Rodriguez, 44, of Tyndall, was indicted on Feb. 11, and appeared before U.S. Magistrate Judge Mark Moreno on Feb. 14. He was also further indicted for being a felon in possession of a firearm, the U.S. Attorney's Office for South Dakota said.

Bonnie Estes, 24, was also indicted for possession of an unregistered firearm. Both Estes and Rodriguez pleaded not guilty to the indictment. The maximum penalty if convicted is 10 years in federal prison and up to a $250,000 fine, along with three years of supervised release.

The indictment alleges that on Dec. 26, 2019, Rodriguez and Estes knowingly possessed a weapon made from a rifle, with a barrel of less than 16 inches in length, which was not registered to them in the National Firearms Registration and Transfer Record.

The investigation is being conducted by the Murdo Police Department, the Lyman County Sheriff’s Office, and the Bureau of Alcohol, Tobacco, Firearms and Explosives. Assistant U.S. Attorney Kirk Albertson is prosecuting the case.

Rodriguez and Estes were remanded to the custody of the U.S. Marshals Service pending trial. A trial date has been set for July 21, 2020.
