This is an image of Jaylen Fryberg taken from his social media. He is alleged to have shot five students, killing one before shooting himself earlier today. The shooting occurred at Washington's Marysville-Pilchuck High School, near Seattle where Fryberg was a freshman.
From a behavioral and nonverbal perspective, this image is highly notable for the emotion of contempt Fryberg is so prominently displaying. In addition, his posting the picture on social media carries additional signaling ... and warning. While every person experiences contempt and thus displays its expression occasionally - it is profoundly important to note that those who commit mass shootings, terrorism and other violent acts display chronic expressions of contempt and/or disgust - and must not be ignored or discounted.
My condolences to those affected by this tragedy.
