• I recently acquired a couple of glass negatives showing the aftermath of a prison break in December, 1935.
• In researching them, I found that five prisoners tried to escape from Charlestown State Prison (Massachusetts) by hijacking a truck as it was making deliveries and ramming it through the prison gates.
• During the breakout, the inmates attacked a truck driver and an inmate who tried to protect the driver. The truck driver was killed in the incident.
•  All the escaping inmates were eventually captured.
  • Charlestown State Prison, a maximum-security prison that housed notable figures like Malcolm X and Charles Ponzi, operated from 1805 until its closure in 1955. The site is now occupied by Bunker Hill Community College.
