MISSING OR MURDERED explores some of the UK’s most talked about crimes

They’re unsolved mysteries which grip Britain – high profile cases which cause agony for families and frustration for police.

Lee Boxell, the 15-year-old from South London whose disappearance led to the longest and costliest forensic dig in Met police history.

Claudia Lawrence, a chef who set off for work and has never been seen again. And Luke Durbin, whose disappearance after a night out in Ipswich led investigators deep into the world of drugs and county lines violence.

No bodies have ever been recovered, so are these much-loved sons and daughters still missing, or were they murdered?
