Upon Dennis’ death in 1968, the prison population buried him nearby within the main yard, fashioning a durable engraved headstone marking his resting place during his funeral services. Today, guests of the Old Idaho Penitentiary regularly pay their respects at his stone, the only marked grave within the prison walls.\n
