The trial of a Muskingum County couple in the death of children started Monday in Muskingum County Common Pleas Court. A jury of 11 men and one woman will make up the group that will hear the case against 38-year-old Richard Klein Jr and 25-year-old Kasey Klein. Earlier Monday afternoon the jury traveled to the Ellis Dam area to see where the Klein’s were camping the day the children went missing. They are being tried in connection with the death of Kasey’s children 3-year-old Ayden Cecil and 2-year-old Anthony Tullius. In June of 2011 the couple was camping near Ellis Dam with the children when they turned up missing. Cecil’s body was recovered fro the river the same day, but Tullius’s body has never been found. The two adults have been charged with two counts of involuntary manslaughter and two counts of child endangering. If convicted each faces 20 years in prison.
