A year after his death, Emiliano Sala's family are calling on the authorities to speed up their work because there are still so many unanswered questions over what happened.
Sala, 28, who had just become Cardiff City's record signing, died when the plane he was travelling in came down over the English Channel.
The news devastated the footballing world and the plane's pilot - David Ibbotson - has still not been found.
The Argentine striker was heading to the Welsh capital from Nantes, where he had played for four years. He was the club's star striker, having scored 42 goals in 120 games.
Cardiff had been monitoring Sala for some time, hoping he could boost the club's chances of keeping their place in the Premier League.
But, in the months after Sala's disappearance, attention soon turned to his transfer fee as both clubs entered a bitter legal battle over who should pay the £15m.
Sala's family are desperate for answers and say they will be marking the anniversary in "private, quiet contemplation of their loss".
