Seann Pietila the 19-year-old who allegedly subscribed to a neo-Nazi ideology, was indicted by a grand jury — and the indictment offers more details about what Pietila allegedly said about carrying out a mass attack.
When they searched his home in Michigan, he allegedly had ammunition, magazines, a shotgun, a rifle, a pistol, various knives, firearms accessories, tactical vests, mask, a Nazi flag, a ghillie suit, gas masks and military sniper and survival manuals. Also seized was Pietela’s phone, and in the Notes app, he had identified a particular synagogue in East Lansing, a date, and a list of equipment.
In communicating with users on Instagram, he allegedly sent pictures that showed Nazi paraphernalia and were supportive of the ideology of the New Zealand shooter.
