Ex-fiancée of killer fears he'll hunt her down after she went undercover for police

A woman who went undercover with detectives after her fiancé confessed to killing a cyclist has told Sky News she fears he will hunt her down one day.

Caroline Muirhead single-handedly helped solve the mystery surrounding Tony Parsons who vanished in Argyll and Bute, Scotland in September 2017.

The 32-year-old doctor said she went to police in November 2020 after her then-partner Alexander McKeller drunkenly confessed to killing the cancer survivor.
