The South Florida man was caught out with DNA recovered from one of the pipe bombs and he has a long criminal history. His white van was covered with Trump stickers and slay-your-enemy slogans. He was none too careful, obviously.
UPDATE: He’s a former New Yorker and an amateur body-builder, sometime male stripper and booking agent for male strippers. Sounds gay but no confirmation of that yet. A registered Republican with long voting history.
