That man with the flare gun and machete that was arrested near the Mayday immigration rally has been identifed by NBC-TV4 as Tyler J. Froatz Jr., age 24. His home, an apartment unit in 5308 8th st NW was stormed by police-who recovered many rifles, several bows, many swords, and what was earlier decribed as a "grenade", now as a replica grenade along with a replica grenade launcher.
