The father of Emiliano Sala, Horacio, has died at the age of 58 following a heart attack, the mayor of the village where he lived said on Friday.
His sudden passing comes just three months after his son, late Argentina striker Emiliano, was killed when the aircraft he was travelling in came down in the English Channel.
"Horacio's wife called me at five o'clock in the morning (0800 GMT). The doctors were already there." said Progreso mayor Julio Mueller.
"He never managed to get over the death of Emi,"
Emiliano, 28, was on his way to Cardiff City after the Premier League side had signed him for a club record £15million (US$19.7million) from Nantes.
The pilot, David Ibbotson, also died in the January 21 tragedy.
Sala's body was recovered on February 7 from the submerged wreck of the plane and his funeral was held the following in his home town of Progreso, Santa Fe Province. The plane was located by a shipwreck hunting company, Blue Water Recoveries, hired by Sala's family thanks to crowdfunding after a search for the plane was suspended.
The late footballer had two brothers, Romina and Darío.
