DECORAH, IA (Ben Caxton) — Prairie du Chien teenager Dalton Adams will be spending the next15 years behind bars for his part in the murder of a Decorah man last year. The 19-year-old was sentenced Tuesday in Iowa District Court for Winneshiek County to 10 years in prison for voluntary manslaughter and an additional five-year term for assault causing serious injury. Adam was initially charged with murder for the July 2018 beating death of 46-year-old David Hansen but a jury found him guilty of the lesser charge of manslaughter. According to court documents Adam choked a man at the Winneshiek County fairgrounds causing him to lose consciousness and fall to the ground. An hour later, he and Jacob Seelinger went to Hansen’s home and began damaging property outside the residence. When Hansen, who was dating Seelinger’s mother confronted the two he was punched and fell to the ground hitting his head on a concrete sidewalk where the two continued to punch and kick him as he lie helpless on the ground. He died about a month later from his injuries. Seelinger has been sentenced to 50 years in prison for second-degree murder.
