What happened to the prisoners when Alcatrez closed down?

Answer 1

When Alcatraz closed down in 1963, the remaining prisoners were transferred to other federal penitentiaries across the United States. The closure was due to the high operational costs of maintaining the facility and the deteriorating infrastructure. Many inmates were relocated to institutions like Leavenworth and Marion, while others were released if they had served their sentences. The closure marked the end of Alcatraz's notorious reputation as a maximum-security prison.
