This spontaneous shrine has been created in memory of the thirteen people killed in the Navy Yard shooting of Monday, September 16, 2013. It is in the 600 block of M Street SE, Washington, DC, just outside the main gate.
It honors Aaron Adams, Arthur Daniels, Frank Kohler, Gerald L. Read, John Roger Johnson, Kathy Gaarde, Kenneth Bernard Proctor, Martin Bodrog, Mary Francis Knight, Michael Arnold, Richard Michael Ridgell, Sylvia Frasier, and Vishnu Pandit. May they rest in peace, and their families be comforted.
The alleged gunman, Aaron Alexis, also died in the shooting episode.

I revisited this memorial recently. There were some additions made to the site, as below.
