PHOENIX (AP) -- A federal jury in Phoenix has convicted an Oklahoma man accused of mailing an inoperable homemade bomb to Maricopa County Sheriff Joe Arpaio.

Gregory Lynn Shrader pleaded not guilty to charges of making a threat by means of explosive material, transportation of explosive material, mailing an injurious item and possession of explosive materials by felon.

Prosecutors say the 56-year-old Shrader addressed the parcel to Arpaio and dropped it off at a U.S. Postal Service collection box in Flagstaff in April 2013.

They say Shrader was trying to frame an ex-business partner.

The bomb was made of smokeless powder, wires, a battery and a pressure-release switch attached to its lid.

Authorities determined the bomb was inoperable, though black power inside the parcel could have exploded or ignited in a flash fire.
