4) In case you missed it: A tragic story from Florida has ties to Woburn. Alanna DeMella, the young wife and mother-to-be from Medford, was killed in a freak accident Sunday. A memorial gathering will be held at her church, Genesis Community Church on Wheeling Avenue, tonight. For full story, click here.

5) ‘The Rock’ closes its doors: On this day in 1963, the infamous Alcatraz Prison in San Francisco is closed. ‘The Rock’ housed nearly 200 dangerous inmates in its maximum-security prison and was inescapable. Some tried to escape, no one succeeded. Known for its famous inmates, like Al Capone and the Birdman of Alcatraz, the prison has an almost mythic quality to it. In 1972, the island where Alcatraz sits was added to the Golden Gate National Recreation Area. Tours are given daily. Woburn Patch recommends if you’re going to be in the area, reserve a spot on one of the night tours—it’s an experience!
