A man convicted of nearly killing a toddler in Mahaska County will remain in prison. Iowa’s supreme court has upheld the child endangerment conviction of Clarence Yeo, Junior, of Oskaloosa. Originally convicted in December 2000, Yeo was granted a second trial over false testimony given to the first jury by the child’s mother, Miranda Charbonneau. She got a lighter sentence of ten years in return for her testimony. Yeo was found guilty in the second trial and sentenced to fifty years in prison for abusing then-2-year-old Frankie Charbonneau Junior, who was near death from severe brain injury. The state supreme court upheld that conviction, and refused to grant an appeal.
