James Albert Hamm was killed after being shot while stopped on his motorcycle at a Beulah and West Arroyo Avenues intersection in Pueblo, Colorado. Hamm, 46, was a lifelong Pueblo resident who worked for more than a dozen years as a custodian at Centennial High School, where he had once been a student. He was known locally for repairing and selling cars and was a father of three.

On the evening of June 15, 1991, five shotgun blasts struck Hamm as he paused at a stop sign; he was found in the street near his motorcycle after his son, James Leroy Hamm, who lived nearby, heard the shots and ran to the scene. Hamm was taken to a hospital and died of his injuries on June 16, 1991. The Pueblo Police Department investigated but the case went cold; no arrests or public identifications of suspects have been made.

Anyone with information about this unsolved homicide is asked to contact Pueblo police.
