In Scotland, a woman faced an unimaginable dilemma: should I marry a murderer? Caroline Muirhead, a forensic pathologist, found herself entwined in the dark world of her fiancé, Sandy McKellar, who confessed to a hit-and-run that claimed the life of cyclist Tony Parsons. This gripping true crime narrative unfolds in the documentary ‘Should I Marry a Murderer?’, premiering on April 29, 2026.
Caroline met Sandy on Tinder when she was just 29 years old. Their initial connection blossomed into something deeper, but as their relationship progressed, shadows began to creep in. Sandy’s admission about his involvement in the fatal accident—where he struck 63-year-old Parsons—turned Caroline’s life upside down. It was three years after the incident that Sandy revealed his secret to her, prompting Caroline to take action.
Key events:
- Caroline contacted the police in 2020 after Sandy confessed.
- In 2021, Tony Parsons’s body was exhumed for investigation.
- Sandy and his twin brother Robert were arrested for murder.
- Sandy was convicted of culpable homicide in 2023.
In an act of bravery and desperation, Caroline helped police locate Tony Parsons’s burial site by marking it with an empty Red Bull can. The emotional toll of spying on her fiancé weighed heavily on her; she recorded conversations with him as evidence while grappling with significant emotional distress and substance abuse. Yet, amid the turmoil, she felt conflicted—Sandy made her feel loved and wanted even as she unraveled his dark secrets.
Reflecting on her experience, Caroline stated, “He said it’s my life or theirs… it was an admission.” This chilling insight into Sandy’s psyche left Caroline questioning not only his actions but also their relationship. Ultimately, she chose not to marry him and instead took steps to assist law enforcement in bringing him to justice.
