Regional Mexican singer Beto Quintanilla died suddenly the evening of Sunday, March 18. He was 57 years old.

Quintanilla, known for an arsenal of daring corridos -- musical stories that often deal with real life events, including, in recent years, drug dealing and border strife -- had been rumored to have died last year in the wake of the murder of regional Mexican singer Valentin Elizalde. News of his death this week again stirred up reports that he had been killed. But Quintanilla died of natural causes in a hospital in Reynosa, Mexico.

Born Quintanilla Iracheta, Quintanilla was known as "El Leon de los Corridos" (The Lion of Corridos). He had long recorded for indie Frontera Records.
