Footballer Emiliano Sala was exposed to high levels of carbon monoxide prior to a fatal plane crash in the English Channel, a report has revealed.
Sala, 28, and pilot David Ibbotson crashed on 21 January while traveling to Cardiff from Nantes in France.
Toxicology tests on Sala’s body showed CO levels in his blood were so great it could have caused a seizure, unconsciousness or a heart attack.
The Sala family’s lawyer said the report raised further questions.
Mr Ibbotson, from Crowle, North Lincolnshire, has still not been found, but it is likely he would also have been exposed to carbon monoxide, the Air Accidents Investigation Branch (AAIB) report said.
Sala’s blood had a COHb (carboxyhemoglobin) level of 58% – a level at which symptoms include seizure, unconsciousness and heart attack, the report said.
It added: “A COHb level of more than 50% in an otherwise healthy person is generally considered to be potentially fatal.”
Daniel Machover of Hickman & Rose solicitors, who represents the Sala family, said: “The family believe that a detailed technical examination of the plane is necessary.
“The family and the public need to know how the carbon monoxide was able to enter the cabin. Future air safety rests on knowing as much as possible on this issue.”
