Arthur Shawcross was an American convicted child killer who was paroled and went on to kill prostitutes in the Rochester, NY area. 
Shawcross claimed to eat some of his victims body parts and dumping their remains in and around the Genesee river.
 
5" x 7" color photograph of Shawcross with his arms around two children.
There is writing on the back which does not look like Shawcross's, and is most likely the writing from his friend from who these were originally purchased.
