Justin Stanfield Thomas was fatally shot Friday after he and his son traveled from Phoenix to a friend's home 90 miles away in the northern Arizona community of Prescott Valley for a surprise visit.
Prescott Valley Police officer Brandon Bonney says the boy found the loaded gun in the home within minutes of arrival, asked a question about it and pulled the trigger. Thomas later died at a hospital.
Bonney says the gun should have been locked away, but that Thomas' friend, whose identity has not been released, was caught off guard by the unannounced visit. No children lived in the house. The child is now with his mother.
