This photo of Ed Kemper recently surfaced on Reddit and was first seen on the Facebook page The Edmund Kemper Discussion Group. The photo links to this website:
There isn’t much information on the site, but they say it will be the definitive account of the life and crimes of serial killer Edmund Emil Kemper III. To be released in 2021. It’s most probably a book. We’ll be on the lookout!
As for this rare photo, it looks like it was taken in the early 1980s at the California Medical Facility in Vacaville, in the cafeteria or in a visitors’ room. It might be that Kemper was having a meal with people from the American Foundation for the Blind in prison, an organization linked to the Vacaville Blind Project, in which Kemper was involved as a reader and a coordinator for many years.
