AUSTIN, Minn. — Preliminary autopsy results show an Austin doctor died after crashing his bike while wearing a helmet.

Austin Police Chief Brian Krueger said Monday that 72-year-old Dr. Richard Schindler's bike crashed Saturday morning on an unpaved bike path near Riverland Community College. Authorities say his injuries were consistent with a bad accident. The cause of the crash hasn't been determined.

Schindler and his friend were scheduled to meet to clear the path to make it safer for other bikers. Kreuger says the friend found Schindler in the water near the bike path.

Schindler retired from his practice in Adams two year go. He still worked shifts in the emergency room at Mayo Clinic Health System in Austin.

Visitation services are scheduled for Wednesday at the Worlein Funeral Home in Austin.
