(KNZA)--A trial has been set for one of three Sabetha teens accused of breaking into and vandalizing the Sabetha High School over the Easter weekend.

17-year-old Seth Harrell pleaded not guilty last week in a Nemaha County courtroom to charges in the case.

A trial was set for August 22nd.

Co-defendant, 18-year-old Marcus Jackson, also made his first appearance in court last week.  A preliminary hearing was set for August 22nd.

A continuance was granted for the third defendant, 19-year-old Grant Meyer, and his first appearance was rescheduled for August 22nd.

All three have been charged with burglary, felony criminal damage to property, theft and consumption of alcohol by a minor.

The trio are accused of breaking into the Sabetha High School on April 15th.  

Police say markers were used to write several racist, hated-based, vulgar messages inside the school and classrooms were spray painted.  In addition, a vending machine was damaged to steal candy.

All three teens remain free on bond.
