A LaMotte man was taken into custody after law enforcement discovered an alleged homemade explosive device at about 6:46 p.m. Sept. 6 at 146 Main St., LaMotte.

The discovery of the device and subsequent investigation by the Jackson County Sheriff’s Office, as well as the state fire marshal, eventually led to the arrest of Aaron Hinke, 45, of 104 S. Main St. in LaMotte.

He was charged with possession of an incendiary or explosive device with intent, a Class C felony.

Officials from the State Fire Marshal’s Office first diffused the explosive device making it safe for deputies to finish the initial investigation at the scene, according to a press release from the sheriff’s office.

Evidence collected during the investigation, including text messages, resulted in Hinke becoming a “person of interest,” and a search warrant was granted for 112 S. Main St. in LaMotte. Law enforcement and state fire marshal officials executed the search warrant and located Hinke. Several items were seized and placed into evidence.

Initial online court documents allege that Hinke placed the explosive device near a shed owned by Kaleb Bee at 146 S. Main St. in LaMotte at about 3 p.m. Sunday and that he admitted to doing so in text messages he sent to Bee.

The sheriff’s office reported that, when questioned, Hinke admitted to making the device and placing it where it was found.

Hinke was transported to the Jackson County Detention Center in Maquoketa. No other details have been released.

Neither the press release nor court documents provide any details as to Hinke’s alleged motives.
