20.) The Babushka Lady

The Babushka Lady is an unknown woman present during the 1963 assassination of President John F. Kennedy. Her nickname arose from the headscarf she wore, similar to scarves worn by elderly Russian women. Wielding a camera and photographing the events in Dallas’s Dealey Plaza, she was spotted by eyewitnesses and has appeared in film accounts of the assassination. Even after most of her surrounding witnesses took cover, she can be seen standing with the camera to her face. Neither she nor the film she may have taken has yet been identified. 

In 1970 a woman named Beverly Oliver came forward and claimed to be the Babushka Woman, though she is generally regarded as a fraud. To this day, no one knows who the Babushka Woman is or why she refused to come forward to offer her evidence.
