A New Haven man accused of making threats to kill, injure and intimidate people and blow up property in Connecticut and elsewhere is facing several federal charges.
Court documents show 51-year-old Gary Gravelle used mail, e-mail, and phone calls to make threats. It says he also sent a powdery white substance with a note claiming it was anthrax.
He also sent a letter threatening to kill President Donald Trump.
Gravelle was arrested in September 2018 for violating the terms of his parole on similar charges.
If convicted, he could spend the rest of his life behind bars.
