Police: Tejano singer Emilio Navaira died of natural causes

NEW BRUANFELS, TX -- Authorities say their investigation into the death of Grammy-winning Tejano star Emilio Navaira shows he died of natural causes due to cardiovascular disease.

The New Braunfels Police Department said Thursday that it's completed its investigation into the 53-year-old singer's death and found no sign of foul play.

Officers were dispatched to Navaira's home in New Braunfels on May 16 after relatives found him unconscious and not breathing. He was pronounced dead at a hospital in New Braunfels, 20 miles northeast of Navaira's hometown of San Antonio.

Navaira was known to his fans as simply Emilio. He was critically injured in 2008 in a tour bus accident in the Houston area. Navaira later pleaded guilty to driving while intoxicated.

He won a 2002 Grammy for Best Tejano Album for "Acuerdate."
