The Lysander man accused of beating his wife to death has pleaded not guilty.           

Pete Trifunovski, 68, was arraigned on a charge of second-degree murder Thursday morning.

Prosecutors say he admitted to investigators that he killed his wife Suzie last month- hiding her body in a storage facility.

A trial date has been set for September 17. But Trifunovski's attorney says they're planning to work on a plea deal with prosecutors.          

Trifunovski is due back in court in about a month.
