Melanie Ostrander, Washington County's assistant elections director, said he came to the South Franklin Volunteer Fire Department in South Franklin Township at about 9 a.m. Tuesday but became irate when he was told he wasn't registered to vote.
Ostrander said the man allegedly "became upset, told the poll workers he was going to go get a gun and come back and shoot them."
Court documents don't list an attorney for Queen and a phone number listed in his name rang unanswered before disconnecting Tuesday.
