A 73-year-old man, Gary Siders Sr., was declared mentally incompetent to stand trial on Wednesday in a case involving 16 grandchildren who were found living in extremely poor conditions at a home in rural southern Ohio. A judge in Vinton County accepted the results of a mental health evaluation report on Siders, and the county prosecutor, William Archer, did not contest the findings. Siders appeared in court seated in a wheelchair. His attorney, Dorian Baum, said after the hearing that Siders' mental health has been deteriorating for years and that it is "not restorable." "It’s not really a surprise to any of us that he’s not been found competent at this point," Baum said. "He doesn’t fully understand or appreciate what’s going on." Siders was charged with 16 counts of child endangerment related to the children, who were rescued on June 30 from a home in Hamden, approximately 80 miles south of Columbus. His wife, Christina Siders; son Gary Siders Jr.; and daughter-in-law, Elizabeth Siders, the children’s mother, have all pleaded not guilty to the charges. Investigators said the children were mostly confined to a small room in the house, which was described as being in deplorable conditions. The children were not enrolled in school, and the family had moved frequently over the past two decades. Neighbors said they had never seen the children before they were discovered. At the time of their rescue, the children ranged in age from 18 months to 18 years, with some described as "feral" and unable to speak. Authorities reported that the children had varying medical conditions. The eldest child was born in May 2008, just two months after Gary Siders Jr., then 18, and Elizabeth, then 15, crossed into West Virginia to marry at the Mason County Courthouse with the consent of her parents, according to court records. Since then, Elizabeth has been pregnant most years, the records show. The case has drawn significant attention due to the severe neglect and isolation the children reportedly faced, raising concerns about their well-being and the legal responsibilities of the adults involved.
