I was told about this website called Strange Fruit and Spanish Moss. They have documented lynching incidents from around the country. One of the ones that was documented was the Laura Porter lynching in Monroe: http://strangefruitandspanishmoss.blogspot.com/2015/10/july-25-1910-laura-porter.html
Laura was the one in my post on Ouachita Parish lynching that was never found, but was rumored to have been drowned in the Ouachita.
