PHOENIX - A June 23 trial date has been sent for an Oklahoma man charged with mailing an inoperable homemade bomb to Maricopa County Sheriff Joe Arpaio.
Gregory Lynn Shrader of Jay, Okla., has pleaded not guilty to the federal charges against him.
Investigators say the bomb was discovered in April 2013 at mail collection-box unit in Flagstaff and was made of smokeless powder, wires, a battery and a pressure-release switch attached to its lid.
Authorities eventually determined the bomb was inoperable, though black power inside the parcel could have exploded or ignited in a flash fire.
Police disabled the bomb.
Authorities say a woman told them that she drove with Shrader to northern Arizona and saw him place the parcel into the mail box wearing surgical-type gloves.
