An inquest finds that a vacationing couple died from carbon monoxide poisoning.

John Cooper and Susan Cooper, a British couple, became ill in a hotel room in Egypt and eventually passed away from carbon monoxide poisoning.

The couple was visiting Hurghada and lodging at the Steigenberger Aqua Magic Hotel. They were from Burnley, Lancashire. After using the pesticide Lambda at lunchtime to treat a bed bug infestation in the room next door, the couple became ill in the early hours of the following day and passed away.

The door next to the couple’s was always locked. Dr. Charles Wilson, the pathologist at the Home Office, determined that carbon monoxide toxicity and heart disease were the cause of death for Mr. Cooper and Mrs. Cooper, respectively. Professor Robert Chilcott, a toxicology specialist, found carbon monoxide in blood samples taken from the couple’s bodies, although he was unable to pinpoint the exact concentration.

According to his theory, the pesticide Lambda is occasionally diluted with dichloromethane in less developed nations, which leads to the body metabolising or ingesting carbon monoxide. Carbon monoxide poisoning could be brought on by an exposure lasting only ten hours. Although he was unaware of the source, Dr. Nick Gent, a former senior medical adviser to Public Health England, concurred that carbon monoxide was present in the Coopers’ blood.
