US folk star Emilio Navaira may not survive the brain injuries he suffered when his tour bus crashed in Texas this weekend. Navaira’s agent has said the Tejano singer, 45 years old, was driving the bus, which crashed into barriers with six others on board. One remains in hospital.
    The bus crashed in Bellaire, west of Houston, when Navaira and his band were travelling back to their homes in San Antonio after playing at a nightclub in southeast Houston. A Bellaire police spokesman said their initial inquiries showed that Navaira was not licensed to drive the bus. They are also trying to find out whether Navaira had been drinking before the accident, which took place at about 5:00am local time on Sunday. Five of Navaira’s six passengers were band members. His agent Joe Casias said bass player Rick Vega was still in hospital suffering from abdominal injuries. The remaining passengers had all now left hospital after being treated for cuts and bruises.
