( Burlington ) - Fired Boone County Water District General Manager Phil Trzop admitted Wednesday to misusing money from the sale of water district scrap metal.

Trzop, the 62-year-old former mayor of Walton, pleaded guilty to violating public trust. Authorities said they found $5,100 cash buried in Trzop’s backyard after his arrest in November. An audit of the water district found there was about $12,000 unaccounted for. The audit also found he had charged $2,600 of personal expenses to his water district credit card.

If he pays restitution in the amount of $29,000 before his sentencing in August, prosecutors will recommend he serve 180 days of a five-year sentence. However if the money is not paid, Trzop faces five years to 10 years in prison.
