Newsweek has been unsuccessful in contacting Auernheimer, who is allegedly been living in the Ukraine after serving jail time over a computer hacking incident. Auernheimer’s Jewish heritage was first reported by Gawker in 2012, though Auernheimer denied the report. Adrian Chen, the author of the story, told Newsweek that the infamous troll volunteered the information about his Jewish ancestry during an interview.

And his mother has confirmed it. Alyse Auernheimer told Newsweek that he was saddened that her son had wished death on children. She added that she had been estranged from him for over a decade.

“He doesn’t like us,” she said, adding that her son comes from a “large, mixed race family” with Native American heritage, and that he most certainly has Jewish lineage “on both sides of his family.”
