The accident happened around noon at the Glenn Park Village Mobile Home Park when the four-year-old was struck by a pickup truck driven by Annette Bigelow, 35, of Mountain Home.
Information provided by witnesses to police indicates that Bigelow was driving into the mobile home park when the four-year-old ran out in front of the moving vehicle. It's believed that speed was not a factor in the accident.
According to the initial investigation, it's possible that Bigelow didn't see the child run out in front of her pickup.
The four year old was initially transported to Boise and was later flown to a Portland area hospital to treat his injuries.
The accident remains under investigation, and anyone with any additional information regarding this accident should contact Officer Ty Larsen with the Mountain Home Police Department at 587-2101.
