However, due to issues at other jails, he was transferred to the 22-acre island.
The now-93-year-old has now talked candidly about his time in prison, stating that the thing that haunts him the most is the sound—or lack thereof.
Hopkins clarified that the institution had very few books and no radio at the time. He informed the BBC that the only noise was the whistling of ships passing by.
“That’s a lonely sound,” Hopkins went on. Hank Williams’ rendition of the song “I’m so lonesome I could cry” comes to mind.
“There was nothing to do,” he added. “You could walk back and forth in your cell or do push-ups.”
Alcatraz ultimately shut down in 1963 – the year Hopkins was released too – however, if Trump gets his way, the prison originally built as a naval defence before being rebuilt as a military prison and later turning federal could reopen.
