ONAWA, Iowa (AP) – Authorities say a business owner was shot by an employee in the western Iowa town of Onawa. Officers who were sent to a storage building around 6 p.m. Sunday found a man suffering from a gunshot wound to one of his legs.  The man was identified as 32-year-old Darren Hieber. Hieber was taken to Burgess Health Center in Onawa and is expected to survive his wound. Iowa Division of Criminal Investigation officials had said Hieber probably had interrupted a burglar. Now investigators say they think Hieber was shot by one of his employees.  Authorities wouldn’t discuss what led to the shooting. No arrest has been reported.
