race of a Pick 4 and the fourth race of a Pick 6 were forwarded to Autotote headquarters in Newark, Delaware and to the track where the race was held. Harn discovered that there was a half-hour delay between the end of the second or fourth race and when the live wagers were forwarded—enough time to alter the results. Harn was uniquely positioned to take advantage of this weak link. He was a "super user"—the highest level of access at Autotote. In fact, he was responsible for maintaining the entire network. He had DaSilva set up an account at the Catskill Off-Track Betting Corporation in Pomona, New York. Harn liked Catskill because its security was fairly lax. Unlike other OTB parlors, it didn't require the bettor to be physically present to open an account, and also didn't have a transaction history file. It was also a fairly low-traffic facility, making it easier to alter bets. He'd set up the system himself, so he knew how it could be exploited. The scheme Harn had DaSilva conduct two dry runs of their scheme. On October 3, DaSilva bet on the Pick 4 harness races at Balmoral Park, about 45 miles from Arlington Park. After the first two races, Harn logged in and altered the original bets on the first two races, then picked every horse in the last two races. As a result, DaSilva netted $80,000 in winnings. Two days later, Harn and DaSilva repeated the pattern in a Pick 6 at Belmont Park. This time, DaSilva scored $100,000. For the Breeders' Cup, Harn had Davis open an account at Catskill in case the authorities got suspicious of DaSilva. Davis then called Catskill from his home in Baltimore to buy a $12 Pick 6 ticket, picking one winner in the first four races. On Breeders' Cup Day, Harn slipped into his office at Autotote. To make sure he was covered, he remotely ejected the backup tape at Catskill before the first race. He then took several calls from Davis while the races were underway. After the fourth race, and half an hour before the Turf, Harn hacked onto the system and tracked down Davis' bet. He then changed Davis' original bet to reflect the actual four winners. After having the Catskill techs reinsert the tape, he bet on every horse running in the Turf and Classic, assuring that he would win. The
