Rey Misterio Snr, a wrestling star, died at the age of 66, just weeks after a family tragedy.
Misterio Snr, born Miguel Ángel López Días, was the uncle of Rey Mysterio, a WWE Hall of Fame entrant.
The masked luchador began wrestling in 1976 and officially retired in 2009.
The Mexican wrestling business Lucha Libre AAA Worldwide shared the devastating news on social media.
The statement read: “We regret the sensitive death of Miguel Ángel López Días, known as Rey Mysterio Sr.”
“We send our most sincere condolences to his loved ones and raise our prayers to heaven for his eternal rest.”
Misterio Snr was born in Tijuana, Mexico, in 1955, and began his career as a boxer before transitioning to wrestling.
Misterio Snr’s death comes just weeks after Rey Mysterio’s father, Robert Gutierrez, died at the age of 76.
Mysterio, 50, paid tribute to his father, saying, “Father, thank you for giving me this life.
“You did more than just provide an example of how to love and maintain a great marriage and raise four sons; you were the example and passed every test till your death.
“Excellent husband, loving father, beautiful grandfather, incredible son & brother, and amazing father in law.”
Mysterio is still active in the WWE, having recently lost a bout after being unmasked.
He recently held the US Championship, which he eventually lost to Logan Paul at Crown Jewel.
