(MCT) — MEXICO CITY — Mexican American singer Jenni Rivera, the “diva de la banda” whose commanding voice burst through the limits of regional Latin music and made her a cross-border sensation and the queen of a business empire, was believed to have died Sunday when the small jet carrying her and members of her entourage crashed in mountainous terrain.

Rivera, a native of Long Beach, Calif., was 43. Mexico’s ministry of transportation did not confirm her death outright, but it said that she had been aboard the plane and that no one had survived the crash. Six others, including two pilots, also were on board.
