The cause of death of MACCRAY School District bus driver Jeannie Waltz has been released. Lincoln County Medical Examiner Dr. Tabb McClusky says the 48-year-old Clara City woman died of heart disease. Waltz was found dead on the bus by members of the MACCRAY Girls Basketball Team after a game against RTR in Tyler on January 18th.

An autopsy was performed by the Ramsey County Medical Examiner, who released the results to Dr. McClusky earlier this month. McClusky says the cause of death was listed as Right Ventricular Dysplasia-Cardio Myopathy, which affects the muscle of the heart, unlike a heart attack which involves blood circulation to the heart being cut off.

McClusky says all the toxicology test results were negative.
