The results of blood tests taken from the body of top footballer Emiliano Sala showed he been overcome by toxic levels of carbon monoxide poisoning prior to his death in a plane crash, an inquest heard.
The Argentina-born striker was joining then English Premier League club Cardiff City in a £15 million transfer from French Ligue 1 side Nantes.
Dorset Coroner’s Court heard the 28-year-old was on a private plane travelling between Nantes and Cardiff on the evening of January 21 2019 when it crashed in the English Channel close to Guernsey.

Also killed in the crash was pilot David Ibbotson, 59, whose body has never been found.
The inquest resumed on Tuesday having been adjourned a week ago for legal reasons.
Last week, pathologist Dr Basil Purdue said Sala had died from severe head and chest injuries consistent with a plane crash.
But prior to his death he had been overcome by carbon monoxide poisoning and would have been “deeply unconscious” at the point of impact with the sea, Dr Purdue said.
He said toxicological tests on samples of Sala’s blood showed a carbon monoxide blood saturation level of 58%, which he described as “severe poisoning”, and suggested the source was the plane’s exhaust system.
Continuing his evidence, Dr Purdue said two blood samples were taken from Sala – one from the iliofemoral vein and a second from the cavity of Sala’s torso.
The first blood sample was sent away for carbon monoxide testing and the second was used to confirm identity from DNA testing. The second sample was later sent to Canada for further testing.
Dr Purdue explained due to decomposition he was only able to take one blood sample from the iliofemoral vein and obtained blood for DNA testing from the cavity.
He said cavity blood was often contaminated and of “uncertain composition”, and could not be relied upon for toxicological examination, although it was acceptable for DNA testing.
“It is not blood, it is blood with an unknown of other things – you are going to be misled,” he said.
Dr Purdue said Mr Sala’s body was in the process of decomposition when he carried out the post-mortem examination on February 7.
“If we had more blood, I would have taken more samples. The fact we only had one bottle is indicative of all we could get,” he said.
Forensic examiner Katherine Baldwin told the inquest the cavity blood sample was stored in a Dorset Police freezer until it was sent off to Canada for testing.
She also confirmed the first sample had been destroyed by a forensic lab after being tested, even though it was part of an ongoing investigation.
The inquest has heard the Piper Malibu aircraft had left Nantes airport at 7.15pm on January 21 for the flight to Cardiff but radar contact was lost at 8.15pm near Guernsey.
The aircraft was located on the seabed on February 3 and Sala’s body was found in the wreckage three days later.
Last year, the businessman responsible for endangering the flight that led to the deaths of footballer Sala and Mr Ibbotson was jailed for 18 months.
Cardiff Crown Court had heard qualified pilot Henderson was unable to carry out the flight as he was spending a romantic break with his wife in Paris.
He hired Mr Ibbotson to fly the plane despite the fact he was not qualified to fly commercially, was not qualified to fly at night and his flight rating for the N264DB flight had expired in November 2018.
Following a criminal trial, he was found guilty of endangering an aircraft and he pleaded guilty to attempting to discharge a passenger.
The inquest, which is taking place at the Town Hall in Bournemouth, is due to last around five weeks.
