10 Wrestlers Who Died In Mysterious Circumstances

10. La Fiera

A former NWA World Welterweight and NWA World Middleweight champion in the EMLL promotion, Arturo 'La Fiera' Casco was regarded as one of the best workers in Mexico during the 1980s.

Remembered for a terrific feud with a young 'Kamikaze' Mitsuhara Misawa, a series which took him to Japan to feud with him as Tiger Mask II, Castro was in a period of semi-retirement when he was murdered in 2010.

Little is known of Casco's life outside of wrestling and even less about the circumstances that occasioned his death. However it is said that he had become heavily involved in drugs during the latter stages of his wrestling career.

Serving a prison sentence for drug dealing in the 1990s, there is ample room to speculate that by 2010, Arturo Casco was deeply implicated in organised crime.

All that is known of La Fiera's death is that he was stabbed five times by an unknown assailant and left for dead on 10 September 2010. Two days later Casco passed away as a result of his injuries in hospital. He was 49-years old. His killer is still unknown, as is the motive for his murder.
