So, basically, a serial killer, by the name of Rodney Alcala, was just convicted for killing four women and a 12 year old girl, of which, he photographed before he abducted her and killed her. However, he had a box full of thousands of of people he photographed. Police released those photos to the public to identify more possible victims of his killings. So far, one #64, was reported missing in '73.
The photos themselves seem to reflect another time and they have an eerie sense about them.
