Al Bradley was a criminal lord and a minor character in the horror novel, It.
Along with his brother George, Al was the dual leader of the "Bradley Gang" (a mob of felons who would often rob and terrorize stores across Derry through out the late 1920's). Al and his entire associates were fatally gunned down by several of the town's members (including It, which disguised itself as a clown wearing farmer overalls during the shooting) in 1930. He was shot several times inside his LaSalle while attempting to flee away.
Very few individuals around Derry would know the truth behind the Bradley Gang's demise, with most assuming that they were killed by law officials outside of Maine.
