Manslaughter and child endangerment charges have been filed against the parents of a four-year old Perryville boy who died of an infection – four weeks after falling off his bicycle and getting cuts and scrapes on his legs. Investigators say the death of Ethan Patrick Williams might have been caused by the filty conditions he lived in – in the family house trialer. His brothers, who are two and six years old, are in protective custody. His parents, Emily and Michael Altom, face four charges each.
