DULUTH, Minn. - Craig Allen Hartline is a convicted sex offender, but when he moved to Minnesota last year he didn't register, which is a felony. He earned $14,000 while working here, but didn't file a tax return and admits he hasn't filed one since 1983.
He also drove his van back and forth across the state, without a license.
