The 53-year-old Il Divo (opera crossover group) star Carlos Marin died due to COVID-19 on Dec. 19. The family said that the singer was receiving treatment in the United Kingdom. They believed that Marin would have had a better chance of survival if he was treated in Spain.

Marin died in the UK after testing positive for COVID-19. He was treated in the Manchester Royal Hospital after contracting the Delta variant. He was placed in an induced coma in intensive care after the virus reportedly attacked his lungs as confirmed by his sister, Rosa. Marin's relatives were with him when he died. Rosa said that her brother's lungs were very compromised and couldn't overcome the virus despite receiving the best treatment that exists.

Meanwhile, Alberto Martin, Madrid-based lawyer said, "I spoke with his mum the day he died and she was saying she was convinced that if had been in Spain, he could have survived."

"It's something that we'll have to analyse when we see all the medical documents because we feel there was time to control his situation and improve things so he could pull through and have his life saved which was the most important thing," he continued.

Marin will be laid to rest Tuesday after a public wake that will be held on Monday in Madrid. His fans can attend the funeral parlor at Saint Isidore Funeral Home while his bandmates David Miller, Sebastian Izambard and Urs Buhler are said to be joining Marin’s family at the private wake in the morning. 

Marin was one of the four classically-trained singers brought together by Simon Cowell, into a group called IL Divo, the band has sold 30 million album copies worldwide since 2003.

His body was taken from the UK to Spain over the Christmas weekend. The singer is expected to be cremated, his ashes being deposited at Our Lady of Almudena Cemetery, where he will be placed alongside his father, in line with his last wishes. Rosa also said that the singer will be wearing his favorite Armani suit, which he mostly used when performing on stage, "he can go to Heaven looking the part and can sing with the angels".

Marin shared his last Instagram post on Dec. 6, a picture together with bandmates, it was the day before he was admitted to hospital.
