(AP) — A December trial is scheduled for an 18-year-old Saronville man accused of vandalizing an old cemetery in south-central Nebraska.

According to court records, Robert Kelly Jr. pleaded not guilty on Friday in Hamilton County District Court. He’s accused of vandalizing Farmers’ Valley Cemetery in August.

A man who lives near the cemetery discovered the damage on Aug. 20. Nearly 50 gravestones had been pushed over and some had been damaged beyond repair.

The cemetery was established in 1876 along the banks of the Big Blue River south-southwest of Henderson.

The trial is scheduled to begin Dec. 11.
