77 year old Gary Stelzer of Coldwater pleaded no contest Thursday morning in Celina Municipal Court and was found guilty of a 1st degree misdemeanor charge of assault. The case stemmed from a September incident where Stelzer allegedly grabbed a child by his hair and sat him up in his seat while Stelzer was working as a Coldwater School Bus Driver. Stelzer was sentenced to a suspended 30 day jail term and a 100 dollar fine. The time will remain suspended on the condition that Stelzer have no similar offenses involving violence or threats of violence over the next 2 years.
