A Grafton man will spend at least five years in jail, and could see more time behind bars, after he was accused of sexually abusing his grandchildren. 63 year old Oliver D. Klein agreed to a stipulated bench trial and was found guilty Monday of one count of aggravated sexual abuse.
Klein had been accused of sexually abusing six of his grandchildren, all under the age of 18, in 2010 and 2011. According to Jersey County Court records, Klein was arrested in September of 2014 and charged with six counts of aggravated sexual abuse. As part of the sentence, Klein will also be labeled as sexually dangerous and will only be released after his five-year sentence if mental health professionals determine he would not be a danger to society.
