A 19 year old white nationalist who participated on a far right forum has murdered one person and injured three others at a California synagogue in what appears to be a hate crime.

He also left an anti-Semitic note before carrying out the terrorist attack. https://www.nbcnews.com/news/us-news/anti-semitic-open-letter-posted-online-under-name-chabad-synagogue-n999211
