JEROME, Idaho (KTVB) -- The Jerome County Sheriff's Office is working to gather information after a 63-year-old Shoshone man said he was shot while driving Monday afternoon.

Ricardo Anacleto Nunez told deputies he was driving with a tow dolly from a farm northeast of Jerome where he works as a mechanic when the bullet struck him. He also said he did not know who shot him. Nunez, who suffered a gunshot wound to the upper left side of his chest, drove himself to St. Luke's in Jerome. He was then transferred to Saint Alphonsus Regional Medical Center in Boise by air ambulance.

A hospital spokesman declined to release Nunez' condition because he may be a victim of a crime. Jerome County Sheriff's Office Chief Deputy Jack Johnson said investigators are trying to piece together what happened, and plan to interview the victim at the hospital Monday evening.

It's unclear whether Nunez was intentionally targeted or struck by accident. Johnson said the public is not believed to be in immediate danger. Anyone with information on the shooting is asked to call the Jerome County Sheriff's Office at 208-644-2770 or dispatch at 208-324-1911.
