Answer: His name was Anton. He was an associate of Viktor Chagarin. Jack, although lying, said Yuri Komarov sends his regards. Chagarin and Komarov were former partners and Chagarin was the one who got Komarov put in jail. By Jack saying Komarov sent him, it made it seem like Komarov was out for revenge on Chagarin (by attacking his associates). The courts offered to reduce Jack's sentence for testifying against Komarov, which allowed Jack to get close to him and help him escape.
