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 plan worked, and they were able to turn their original $1,152 bet into almost $3.1 million in winnings--$2.57 million for winning the Pick 6, plus $498,000 in consolation prizes for picking five out of six winners. ==Suspicions mount==
