Missing: Race Against Time

A handful of missings persons cases hit the headlines - including Madeleine McCann, Shannon Matthews and 'Canoe Man' John Darwin - but most people who go missing never make the newspapers.

Some choose to disappear, some are found too late and others just seem to walk out of their lives, leaving their families desperate for answers and the police in a race against time to find them.

Three days after 81-year-old Josephine O'Hara disappeared, her daughter Pauline contacts the police. Elderly and vulnerable, she may also have taken her life savings of £10,000 with her, and the police don't even have her photograph.

Meanwhile it's been 36 hours since 25-year-old Adam Warren left home for an appointment at the job centre. He was expected back within the hour by his girlfriend Katie and their 11-week-old-baby daughter Ellie, but he's vanished.

And five years ago another young father, Vinny Derrick, disappeared after a night out with friends. His wife Vicki still has no idea what happened to her husband, and seven-year-old Lewis has grown up not knowing his dad.
