There was a story where a young girl went missing. Crime Patrol showed how the police used all available resources, from interviewing neighbors to analyzing CCTV footage. In the end, they found the girl who was being held captive in an abandoned building. It was a story of hope and the dedication of the police force.
Another great story is about a missing person. The person had vanished without a trace. The Crime Patrol team interviewed friends, family, and neighbors. They discovered that the missing person had some financial troubles and was last seen with a loan shark. After some intense investigation, they found the missing person held captive by the loan shark in an abandoned building.
