New docu-series shows how forensic scientist caught Bullseye Killer

John Cooper was convicted of 2 double murders, a sexual assault and a rape

A NEW true crime documentary series will come to our screens later this week, detailing how a forensic scientist assisted in the conviction of the Bullseye Killer. 

‘Cold Case Forensics’ will delve into the world of Dr Angela Gallop, a forensic scientist who helped solve the Pembrokeshire Murders and lead to the conviction of John Cooper. 

Dr Gallop examined 20-year-old evidence and discovered trace amounts of blood, textiles and DNA, establishing a direct link between Cooper and his victims – Gwenda and John Dixon, and Richard and Helen Thomas. 

The new three-part documentary series will premiere on ITV on Thursday, February 2 at 9pm. It will look at Dr Gallop’s work on three key cases. The first episode will look at ‘The Murder of Rachel Nickell’.

William Clegg QC, a retired defence lawyer who specialises in serious crime, said: “She is the doyenne of her profession,

“If I had a forensic issue in a case, then it was always the same instructions to the team: phone Angela Gallop.”

Dr. Gallop had no intention of making a career out of investigating murders. She first studied botany at the University of Sheffield before moving on to biochemistry at Oxford. 

She joined the Forensic Science Service (FSS) after realising that just a few people were interested in her doctoral research on sea slugs on the Isle of Wight.

Four years later, Dr Gallop visited her first crime scene in search of evidence concerning the murder of 18-year-old Helen Rytka, who was eventually proven to be a victim of Peter Sutcliffe, who is most commonly known as The Yorkshire Ripper.
