“Outraged” means raped.
This is the part of the research I hate: Child murders. My imagination is pretty god and when I come across stories like this (and back then they did not spare details) it puts me in a seriously bad mood. I also understand why lynchings were so common when dealing with stuff like that: No police to speak off and no true homicide investigators, with luck a smart local sheriff that may happen to find himself dealing with a depraved but dumb murderer who left enough clues to be found and arrested. Later the night of the arrest, the locals would pay a visit to the jail and convince the deputy (mostly at gunpoint) to let them have the prisoner for nighttime festivities.
And before you lose your minds, one of the things I have also learned in this research is to hate lynchings. Angry people gathered in a mob fueled by rage, commit some of the most barbaric crimes you can imagine.
Evil has not changed, it just changed clothes and means.
