This episode covers the murder of Julie Hogg, the acquittal and later confession of Billy Dunlop, and the campaign led by Ann Ming to change the double jeopardy law.
Julie Hogg, a 22-year-old mother, went missing in November 1989. Her body was discovered under her bathtub in February 1990 by her mother, Ann Ming. Ann describes the traumatic experience of finding her daughter and the subsequent investigation that led to Billy Dunlop being identified as a suspect.
Despite strong evidence, including fingerprints and DNA, Dunlop was acquitted of murder in 1991 after two trials. Ann Ming's fight for justice intensified after Dunlop's confession in 1999, which was hindered by the double jeopardy law that prevented retrials.
Ann Ming campaigned tirelessly to change the law, leading to its eventual repeal in 2005. This allowed for Dunlop to be retried, and in 2006, he was finally convicted of Julie's murder, receiving a life sentence.
The episode highlights the impact of the case on Julie's family, especially her son Kevin, and Ann's determination to seek justice for her daughter, resulting in significant legal reform in the UK.
Julie Hogg's murder led to a historic legal battle and the eventual conviction of Billy Dunlop after Ann Ming changed the double jeopardy law.
