A MAN convicted of manslaughter by gross negligence when a sex game went wrong has been jailed for two years.

Kevin Lewis Adams, 54, of Exmouth Street, was found guilty by a jury sitting at Bristol Crown Court on Friday.

On Saturday, June 13, 2015, paramedics and police were called to Adams’ home address in Exmouth Street, Kingshill, following the sudden death of 36-year-old Kim Dohoon, originally from South Korea but who was living in Slough at the time of the incident.

Adams was arrested in connection with the death and a post-mortem examination which revealed Kim died as a result of a partially obstructed airway and mixed drug intoxication.

The jury heard that Kim wore a gas mask and was tied up.

But after a sex session, Adams fell asleep, leaving Kim naked and trussed up on the floor, with a rope around his neck which restricted his airways.

Adams, who had denied manslaughter by gross negligence, was jailed for two years by Judge Neil Ford QC.

The judge told him: "I have been urged to pass a sentence that falls within the sentences that could be suspended.

"I regret to say I cannot agree with this submission. Even though this death can be regarded as a tragic accident it nonetheless was caused by your gross negligence and I cannot lose sight of the fact a life was lost."

Judge Ford described the case as "very unusual" and told Adams: "You and the deceased had met on a website for those who are interested in what can be properly described as 'extreme homosexual practices'.

"You were the dominant partner and Mr Kim the submissive."

Adams had previously pleaded guilty to three counts of possession of Class A, B and C drugs and Judge Ford imposed no separate penalty.

Pavlos Panayi QC, defending, said Adams was the main carer for his 84-year-old father who was in poor health.

"It is a phrase that is often overused in a crown court but this is a case that can be described as a tragedy," he said.

"Nobody intended any harm to come to anyone that night. It is a tragedy for Dohoon Kim, his family, his partner and friends.

"It is tragedy that this defendant failed to flick a carabiner and if he had, Dohoon Kim would have lived."

During the trial, the court heard the emergency services attended Adams' terraced home after he called 999, reporting that he had found Mr Kim unresponsive and not breathing.

Paramedics attended and found Mr Kim, from Slough, had been dead for some time and could not be resuscitated.

A post-mortem examination found Mr Kim had low levels of GHB in his body and an "excessive" level of M-Cat.

Mr Kim was born in South Korea and moved to the UK in 2001, meeting his partner Mark Ciccone a short time later. The couple began living together in 2012.

Jurors heard Mr Kim was a "submissive" who regularly met "dominant" men - including Adams - for sex, with the permission of Mr Ciccone.

Detective Chief Inspector Jeremy Carter, of the Brunel Major Crime Investigation Team, said: “This was a tragic and needless death of a man described by his work colleagues as an industrious and ambitious person who clearly had a bright future ahead of him.

“Kim had spent the evening at Adams' home address in Swindon where the pair had taken a cocktail of drugs before engaging in sexual activity involving restraint and bondage activity.

“Adams had a responsibility to look after Kim’s welfare and he failed to do so with tragic consequences.

"The restrains which had been placed on Kim, together with the mixture of drugs both men had taken that evening, proved fatal.

"It was Adams' failure and his care towards Kim which ultimately led to his untimely death.

“I would like to take this opportunity to express my sincere condolences to the family and friends of Kim.”
