Bio

Stuart Harling was born in 1988 and lived in Rainham, Essex, England. Public reporting described him as a bright but socially isolated teenager. As a child, Harling attended Campion School in Hornchurch and was considered academically capable. Reports stated that he had been an altar boy, a scout, and later completed accounting qualifications after leaving school. However, he also had difficulty socializing and was described as a loner.

After leaving school at 16, Harling studied accountancy at Havering College. Although he gained qualifications, he did not complete the work experience required to continue his career path. Instead, he spent increasing amounts of time alone in his bedroom using the internet and playing computer games.

In the months before the murder, Harling became heavily focused on violent material, weapons, and serial killers. His internet searches included notorious killers, combat techniques, knives, and murder-related topics. He also owned violent computer games and researched methods of killing.

Harling later told psychiatrists that he had dreamed of becoming a serial killer after watching a documentary about American murderer Richard Ramirez. Prosecutors argued that he wanted notoriety and had planned to become known as a killer.

During the ten months before the attack, Harling assembled what prosecutors called a “murder kit.” He bought items including a hunting knife, leather gloves, sunglasses, a jacket, and a wig. He also obtained a knife-fighting instruction manual associated with military combat training.

Before the murder, he reportedly carried out practice walks or “dry runs” in Hornchurch Country Park. Investigators later found that two days before the killing, he had searched online for phrases such as “serial killer Essex,” “serial killer Romford,” and “serial killer Havering.”

Murder Story

On April 6, 2006, Stuart Harling left his home carrying a hunting knife and other items from the kit he had assembled. That morning, 33-year-old Cheryl Moss was working at St George’s Hospital in Hornchurch, Essex. During her shift, she went outside for her usual cigarette break on a secluded path near the hospital grounds. Harling spotted her and waited until she finished speaking on her mobile phone. Wearing a wig and sunglasses, he approached her with the knife.

He attacked Cheryl from behind. She was stabbed and slashed more than 70 times. Reports vary between 72 and 73 stab wounds, but all sources describe a prolonged and frenzied attack. The injuries were inflicted to her head, face, back, arms, and body. One wound was so forceful that it split her skull. Many injuries were inflicted after she had fallen to the ground and could no longer defend herself.

Cheryl was found by hospital staff and a dog walker. She died at the scene. After the murder, Harling dumped his knife, wig, and other items in the nearby park. Within an hour, he was back online looking for news reports about the killing. Police quickly recovered the discarded murder kit. Harling had accidentally left his address among the items, which led investigators directly to him.

He was arrested the following day at his parents’ home. Harling admitted killing Cheryl Moss but denied murder, claiming manslaughter on the grounds of diminished responsibility. His defense argued that he had a mental disorder, possibly Asperger’s syndrome or another condition. Prosecutors argued that the killing was planned and deliberate.

During trial at the Old Bailey, Harling behaved disruptively, insulted the judge and prosecutor, and refused to attend parts of the proceedings. He also claimed the murder was connected to a bizarre plan to steal a car and stage a coup in Equatorial Guinea. The jury rejected his diminished-responsibility defense.

On June 28, 2007, Harling was convicted of murder by a majority verdict. The following day, he was sentenced to life imprisonment with a minimum term of 20 years. Judge Brian Barker said Harling had put his violent research into practice and that Cheryl Moss had the misfortune to cross his path. Police stated that they believed Harling would likely have killed again if he had not been caught. Stuart Harling remains imprisoned under his life sentence.
