OTTAWA, Illinois – A Mason City man has been found guilty of involuntary manslaughter in Illinois.

Mason Shannon, 43, was accused of choking Michael Castelli to death in La Salle County in July 2017. He was arrested in Cerro Gordo County and extradited to Illinois, where he originally faced a murder charge.

That count was dropped and his bench trial took place from September 4 through September 7. A judge issued a guilty verdict Thursday and Shannon’s sentencing is scheduled for November 16.
