W5's Avery Haines meets the men who are working to bring renewed hope to the families of missing people. 

The cases date back more than 30 years. Despite the fact these missing person files are “still active” in the eyes of police, the families have given up hope that the mysteries of what happened to their loved ones will ever be solved, until now.

A renewed sense of optimism rests on the shoulders of two local men who have set up a non-profit organization called "Please Bring Me Home."

Nick Oldrieve, a one-time youth worker, and Mathew Nopper, a former reporter, have taken on the seven historic missing person files. They follow up on anonymous tips to their website, interview witnesses and have even carried out more than a dozen excavations and searches, aided by volunteer experts in forensics and search and rescue.
