The Missing Father - Part 2 - S1.E84

Chasing the lead of a photograph of the boy's father, taken some time ago, CID officers find out that it was taken as a part of a fraudulent program that promised to help people begin a new life in Japan, of which the father was a victim. They find out that after he was defrauded, he went into a life of crime- becoming a thief to try to earn back his money. As fate would have it, he was only recently released from prison. The search carries on.
