An investigation by Margo MacDonald
Five-year-old Caroline Hogg was abducted from Portobello near Edinburgh on the evening of 8 July 1983. Her body was found ten days later in a lay-by near Twycross in Leicestershire. Why is her killer still at large? After 18 months of painstaking enquiry the police still haven't made an arrest. But in tonight's programme they review new information they think will lead them to Caroline's killer. Key witnesses who saw Caroline at the time she was abducted talk about what they saw -and felt-that evening.
