A judge has found a Perth Amboy school secretary guilty of possessing and selling alcoholic beverages on school grounds without the permission of the school board.

The judge ordered Hector Muniz to pay $664 in fines and fees.

Muniz is on paid administrative leave from the Richardson 21st Century Elementary School in Perth Amboy.

School Superintendent Janine Walker Caffrey tells the Home News Tribune  the key for her was the finding that no one in the administration gave permission or had knowledge of what Muniz was doing.

Muniz was placed on leave in June 2012 after receiving a second summons for selling a Latino-style eggnog containing rum to school staff members.

Muniz said he had alcohol in the trunk of his vehicle parked in the school lot.
