A Floyd County jury has found a Waterloo man guilty of killing a Grundy Center man who went missing in 2017. Jurors deliberated for about two hours yesterday(Weds), before finding 29-year-old Armando Adame III guilty of first-degree murder and possession of an offensive weapon in the death of 27-year old Michael Johns. Sentencing will be in March, but murder carries a mandatory sentence of life in prison without parole.
Floyd County Attorney Rachel Ginbey said Adame, Johns and Brandon Rathbone had attempted to get methamphetamine from a person in Marshalltown on Oct. 24, 2017. The Marshalltown man needed a ride to Charles City to his girlfriend’s house, and after driving him, the three realized they had been given a bag of ibuprofen and not meth. After the seller barricaded himself in the house and refused to come to the door, the trio left Charles City around 6 a.m. Oct. 25, 2017, and Adame allegedly became suspicious, believing Johns was in on the rip off. Adame had Rathbone stop the vehicle on a gravel road in rural Floyd County, retrieved a gun from the truck and shot Johns in the head. Family members reported Johns missing to Grundy Center police the following day, and he remained missing for months.
Johns’ remains weren’t found until Dec. 1, 2017. A farmer discovered his body in a deep ditch near 290th Street and Shadow Avenue about 10 miles south of Charles City. An autopsy determined he died of a gun wound to the head, and the location coincided with the area where his cellphone was last active, according to prosecutors.
