Life publishes 12 unpublished photos from the day Martin Luther King, Jr. was killed.

For reasons that have been lost in the intervening decades, Groskinsky’s photographs from that eerily quiet night in Memphis — taken at the site, and on the very day, of one of the signal events of the 20th century — were never published in LIFE magazine, and the story behind how they were made was never told.

Interesting photos of what went on later that evening. I wonder where that jar is today?
