The upcoming documentary Did You Kill Emma? delves into one of Scotland's most disturbing cold cases, the murder of 27-year-old Emma Caldwell, whose killing went unsolved for nearly two decades before a breakthrough conviction.
Emma Caldwell disappeared in Glasgow in April 2005, and her body was later discovered in Limefield Woods near Biggar, South Lanarkshire, several weeks after she went missing.
The case remained unresolved for years before being reopened following renewed scrutiny and fresh investigative work.
Investigative failings were criticized, with former officers stating that warning signs about a suspect's behavior were not properly acted upon at the time.
Police Scotland later acknowledged failings in the handling of the case and issued an apology to Caldwell's family and other victims following the eventual conviction.
In February 2024, Iain Packer was convicted of the murder of Emma Caldwell, along with multiple other serious offences involving sexual violence against 22 women.
He was sentenced to life imprisonment with a minimum term of 36 years, backdated to 2022.
The series is expected to release on Prime Video in June 2026 as part of its true-crime slate.
