A town of Ahnapee man pleaded no contest Tuesday to a charge of possession of improvised explosives.

James Gigstead, 40, was arrested in December 2015 after a search warrant of his home along State Highway 54 turned up three improvised explosive devices and materials that could be used to build more, along with numerous guns, according to the criminal complaint.

In a plea agreement Kewaunee County District Attorney Andrew Naze moved to dismiss a second count of possession of firearms by a felon. Court records indicate Gigstead has a previous conviction for manufacture and delivery of THC, the active ingredient in marijuana.

The search warrant was obtained and executed after neighbors reported hearing occasional loud explosions from Gigstead’s property in the months leading up to his arrest.

Judge Keith Mehn scheduled sentencing for Oct. 26.
