An explosion Tuesday afternoon outside of a public shooting range in Deschutes County resulted in the deaths of two people, according to the the Deschutes County Sheriff’s Office.

Deschutes County deputies, along with Oregon State Police and the Bend Fire Department responded to a report of an explosion at a gun range east of Bend about 3 p.m. Tuesday, according to a release from the Deschutes County Sheriff’s office.
