He broke into people's homes by jimmying the backdoor locks with a screwdriver. After that, he robbed them while wearing socks. If interrupted, he acted violently and killed, or tried to kill, his victims.
He was a petty burglar until he killed a woman, and then was represented by defense attorney, Ellen Wolf.
Six months before his break-in at the Morton house, he broke into an old woman's house and when she interrupted, he pushed her down the stairs and escaped prosecution with the help of defense attorney Ellen Wolf when the victim couldn't ID him in a line-up. Afterwards, he broke into another house. When he was discovered by a young college student named Lisa Morton, Chung tackled her, killed her, and fled. He was wearing socks at both crime scenes, which led Masuka to believe that he was the one who had killed Lisa. Masuka showed hatred towards Chung, stating that "he gives Asians a bad name." Wolf tried to get Chung's charges lessened, as well as several other benefits, in exchange for his surrender. This ended in a serious argument about him with Miguel Prado at the police station. However, Wolf later helped LaGuerta turn him in to the police. Although he was never seen, Chung looked like Masuka, according to his picture.
