During the original murder trial in 2004 and the retrial in 2007, Coutts said that he had a
fetish for necks and
strangulation. His testimony, confirmed by witnesses, stated he had engaged in
breath control play with several consenting partners on many occasions without incident over several years. The Court heard that Coutts had sexually arousing murderous thoughts about women since he was 15,
Consultant psychiatrist Larry Culliford testified that he had seen Coutts in 1991, 12 years before the murder, and that Coutts told him that he feared his thoughts might lead to criminal action. The defence claimed that this was evidence that the deceased had engaged in activity with another partner, similar to that claimed by Coutts. Longhurst's boyfriend and a previous lover stated that they had not indulged in erotic asphyxia with her. He visited the storage unit 11 times while the body was there. The Court heard that Coutts hid Longhurst's body for a month and that it was found in secluded woodland after he set it on fire.
Pathologists' expert testimony Home Office pathologist Vesna Djurovic testified that Coutts must have been aware of the medical emergency for two to three minutes before death became inevitable. Had Coutts acted on this emergency as soon as he became aware of it, Longhurst would definitely have survived. By continuing to constrict her neck with a ligature long after becoming aware of the emergency, Coutts showed the necessary
mens rea for murder. Djurovic said that Longhurst's death could have been from heart attack or
vagal inhibition, but in her experience, these were unlikely mechanisms. Djurovic's evidence was contested by defence pathologist, Richard Shepherd, whose expert opinion was that death could have occurred very quickly by vagal inhibition, taking as little as one or two seconds. ==Murder conviction and appeals==
