The wife and daughter of pilot David Ibbotson, who was flying the plane carrying Emiliano Sala, have said they will never give up hope of finding him.
The initial search for the missing striker and Mr Ibbotson was called off on January 24.
Pilot David Ibbotson was also onboard when it vanished from radar - although his body is still missing.
It led to the discovery of the Piper PA-46 Malibu aircraft and a body, formally identified as Sala.
"The cause of death, which was established after a post-mortem, is given as head and chest injuries".
SAC has repeatedly refused to publicly name the owner of the plane, but clarified on Monday night that the Air Accidents Investigations Branch has been informed.
Wreckage of the plane was later located on the seabed around 21 miles north of Guernsey before Mr Sala's body was recovered following a privately funded search last week.More news: PM: Naidu is Senior in Back-stabbing His Father-in-law
Many expressed outrage that he clumsily asked the family why they wanted Ibbotson's body back, sparking a flurry of angry tweets about his insensitivity.
"If you do not have any more news from [me] in an hour and a half, I don't know if they need to send someone to find me".
The Bluebirds have won their last two games, beating Bournemouth and Southampton respectively, but manager Neil Warnock felt it right to abandon the trip as his players continue to recover from recent events.
Cardiff's 2-1 weekend win at Southampton was dedicated to Sala by Warnock and midfielder Aron Gunnarsson said the Argentine striker's death had "brought everyone together" at the club.
Southampton have released a statement on the incident, saying, "Southampton Football Club can confirm that two fans were detained and had their details taken by police during our match against Cardiff City on Saturday".
"The most important thing was for the family to mourn".
