San Diego Police confirmed one fatality and three injuries in the Saturday morning shooting at the Chabad of Poway on the last day of Passover.
Multiple law enforcement sources confirmed to NBC News that San Diego Police had taken John T. Earnest into custody after the shooting.
A user self-identifying himself as John Earnest posted a white nationalist open letter to the far-right message board 8chan. He also used the username "JohnTEarnest" to post the letter on a document hosting site.
The link to the anti-Semitic note was put online shortly after 9 a.m. PT on Saturday and posted to 8chan, along with a link to a Facebook page and says "a livestream will begin shortly."
There is no active link to a livestream on his Facebook page. The post also includes a link of songs the poster planned to play during the stream.
The 8chan post appears near identical to the one Brenton Tarrant left hours before opening fire at a mosque in Christchurch, New Zealand. It even links to the same document dumping sites PasteBin and MediaFire to host the open letter.
The attached note is similar in both format and tone to the one written by Tarrant, who killed 49 people last month. Tarrant and Pittsburgh synagogue shooter Robert Bowers are listed as a direct inspiration in the letter, which is riddled with almost exclusively anti-Semitic tropes and advocacy for white supremacy.
