OTTAWA, Illinois – A North Iowa man is no longer facing a murder charge in an Illinois killing.
Mason Shannon, 43 of Mason City, is accused of choking to death Michael Castelli in La Salle County, Illinois in July 2017. Shannon was arrested in Cerro Gordo County on an outstanding warrant and extradited to Illinois, where a charge of murder was then added against him.
Shannon’s trial was to have begun Monday but it has now been postponed for a fifth time to September 4. The murder charge against him has also been dropped so he will be tried only for involuntary manslaughter.
