A former Marion school district teacher will serve prison time on a child enticement conviction. 45 year old Timothy A. Gast pleaded no contest to the felony charge, and was ordered to serve two and a half years in prison, and two and a half years on extended supervision following his release. Three other charges, including repeated sexual assault of a child were dismissed in the plea deal, but read in for sentencing. Gast sent inappropriate text messages, and had sexual contact with a 14 year old Marion student in 2013. The student came forward to authorities in April of 2017.
