Argentine health insurance company Swiss Medical acknowledged that medical tests presented during the trial over the death of football icon Diego Maradona actually belonged to his father, who was also named Diego.
In a letter seen by AFP on Monday, Swiss Medical admitted that tests it released to a medical commission investigating Maradona's death "remained mistakenly filed under the name Diego Armando Maradona" when, in fact, they belonged to his late father, Diego Salustiano Maradona.
The older Maradona died in 2015, five years before the man considered one of football's greatest ever players. A lawyer defending one of the seven healthcare professionals on trial over Maradona's November 2020 death spotted the blunder last week.
Maradona died of heart failure and acute pulmonary edema—a condition in which fluid accumulates in the lungs—at a rented home in the Buenos Aires suburb of Tigre two weeks after undergoing surgery for a brain clot.
His medical team is accused of providing grossly inadequate care leading up to his death, though it denies the charges.
His kidney health has been a core focus of the final stages of the trial, with a nephrologist testifying that his doctors should have paid more attention to the issue. It turns out the specialist based his analysis on the wrong test results.
The mix-up led to a one-week suspension of the proceedings, causing further embarrassment for the court after the first trial collapsed last year over a conflict of interest involving one of the judges.
The latest trial, which began in April, resumes on Thursday. It is expected to continue until at least September.
