Halvorson was employed as an aquatics coordinator at the Clark Swim Center at Heather Farm Park in Walnut Creek when he was accused of dipping into pool rental fees, taking amounts of $20 to $60 per day, according to reports. He tampered with the computer to cover the discrepancies.
Halvorson originally pleaded not guilty when charged with the crime in October 2007.
At the same time Walnut Creek's aquatics supervisor Jeff Tarpley, 49, of Fairfield, was charged with stealing more than $150,000 from the city's two swim centers but the cases were found to be unrelated. n
