Missing Live - 2007 - Episode 5

Sally Magnusson presents a series that goes behind the scenes at police forces' Missing Persons Units across the UK and looks at baffling cases from the National Missing Persons Helpline. In August 2004 Brian Watson walked out of a Derby hospital and disappeared without a trace. Vinny Derrick didn't return home after a night out in 2003, and his disappearance sparked a massive manhunt by Greater Manchester police.
