Late on the night of June 11 or early morning of June 12 , inmates Clarence Anglin , John Anglin , and Frank Morris tucked heads made out of soap wax resembling their own likenesses into their beds , broke out of the main prison building via an unused utility corridor , and departed Alcatraz Island aboard an improvised inflatable raft to an uncertain fate .
