Sin escaped from Pusan Penitentiary in
Pusan on January 20, 1997, through a bathroom ventilation shaft. He had dieted to lose weight in order to fit in the air shaft, and spent several months sawing through metal bars that blocked its outlet. It was determined that the bills had been stolen during several break-ins in the wealthy
Bangbae district of Seoul. According to the diary, Sin had previously hidden from police by climbing into manholes. This discovery led police to undertake a search of the sewer system in the vicinity of
Daemosan in
Gangnam, Seoul, in July 1998, without results. Soon after this, the reward for assistance in capturing Sin was increased to 50 million
won, the largest reward offered by South Korean police until that time. The diary revealed that policemen had stopped the fugitive for minor offenses several times since his escape. On May 4 he had been found driving a car in Daegu with an illegally darkened windshield, and on July 9 he was confronted for smoking in a no-smoking area in
Yangjae-dong, Seoul. In each case, Sin presented stolen identification cards, and police failed to notice that his face did not match the photographs. According to authorities, Sin committed 104 thefts, five burglaries, and one rape during his years on the run, among other crimes. He also claimed to have given thousands of dollars to orphanages, the homeless, and disabled students during the same period. ==Public response==
