Dr Angela Gallop, CBE, is an honorary graduate of The University of Sheffield and highly influential in the world of forensic Science.
In this interview, Dr Gallop tells us the story of how she took a cold case from a frustrated police team and broke it wide open with new evidence that led to the conviction of a serial murderer.

Angela has been highly influential in the world of forensic science, helping to solve many well-known cases including the murders of Stephen Lawrence and Damilola Taylor. We caught up with her when she visited Sheffield and asked her to tell us the story of the Coastal Path Murders, a case which spanned 24 years, two double murders and all hinged on a trace of DNA found on one item of clothing.
