Emma Caldwell: The final day of a 19-year murder huntpublished at 18:30 Greenwich Mean Time 28 February
Almost 19 years after Emma Caldwell's body was found in remote woods, Iain Packer has been jailed for at least 36 years for her murder.
The 27-year-old's death in April 2005 had been one of Scotland's most high-profile unsolved murders.
After the jury delivered its verdict, BBC Scotland News revealed that the police missed the chance to catch Emma Caldwell's killer in the months after her murder because senior officers repeatedly dismissed him as a suspect.
BBC Scotland reporter Sam Poling interviewed Packer twice as part of an investigation which helped pave the way for his arrest.
The trial judge, Lord Beckett, told Packer his actions have had “terrible and enduring consequences” for his victims.
Emma's mother Margaret Caldwell told BBC Scotland News she could "breathe again" now that her daughter's killer had finally been found guilty.
Police Scotland has apologised for how the original inquiry was handled by what was then Strathclyde Police.
The writers for today's live coverage were Paul O'Hare and Craig Hutchison. The editors were Graeme Esson and Paul McLaren.
Catching a Killer: The Murder of Emma Caldwell will be shown on BBC Scotland on Wednesday at 21:00 and later on BBC Two at 23:15. It will also be available on the BBC iplayer.
You can listen to the podcast series Who Killed Emma? on BBC Sounds.
