TV show follows police investigating Una Crown's murder
The Garden ProductionsA cold case involving an 86-year-old widow who was brutally murdered in her own home will feature in a TV documentary about a police force.
Family members and a neighbour discovered Una Crown's body in her bungalow in Magazine Lane, Wisbech, Cambridgeshire, in January 2013.
A "terrible mistake" meant her home was not treated as a crime scene by the first officers on the scene. Her killer lived free for more than a decade.
Channel 4's 24 Hours in Police Custody follows Det Supt Iain Moor and colleagues as they reopen the investigation, "finally getting justice and closure for Una's family".
"When I joined the Major Crime Unit, the first thing my wife said to me was, 'You've got to solve this murder'," he said.
The Garden ProductionsCrown died from stab wounds to her neck and chest, and her clothing had been set alight in an attempt by the killer to disguise her injuries and destroy evidence.
The case lingered on unsolved for years until the Major Crime Unit - shared by Bedfordshire, Cambridgeshire and Hertfordshire police forces - re-opened the investigation.
Detectives pieced together more evidence and uncovered new information.
New forensic techniques revealed male DNA under Crown's fingernails, protected under her body and in her clenched fist when she fell to the floor.
The DNA matched a neighbour and odd-job man, David Newton, but detectives had to rule out all male relatives in his paternal line to build a strong case against him.
The Garden ProductionsMoor said: "For more than a decade, David Newton thought he had got away with this most horrendous crime.
"He was hiding in plain sight, but jurors saw through his lies, and as this programme highlights, you cannot hide forever."
Newton was jailed for life for murder in February last year.
The Garden Productions"I'm immensely proud of bringing Newton to justice after more than a decade, and finally getting justice and closure for Una's family," said Moor.
"Una, by the actions she took on that night, solved her own case as she fought her attacker."
24 Hours in Police Custody: The Cold Case Murder starts at 21:00 BST on Channel 4 and concludes on Tuesday.
