LOCKPORT – A Niagara Falls man who allegedly stole $20,000 worth of metal, pipe and wire from a Town of Niagara business has been indicted after he missed a deadline to pay restitution to the company.

Gerald D. Zimmernan, 53, of Lockport Street, pleaded not guilty Friday in Niagara County Court to third-degree grand larceny and second-degree criminal mischief, allegedly committed in late 2011 and early 2012. He purportedly got inside the business by saying he was interested in leasing space.

At a Sept. 13 court appearance, Zimmerman was given three months to pay back 3425 Hyde Park Inc., located at the former Carborundum Co. electrical products division. If he had paid the money, Zimmerman would have been offered a misdemeanor plea that would have kept out of state prison.

Zimmerman is a Level 3 sex offender who served state prison time in 2008 for violating the terms of his probation on an attempted first-degree sexual abuse conviction. He also violated parole on that charge.
