A case of voter fraud in Oregon leads to an even bigger federal investigation.  Lafayette Fredrick Keaton, 81, of Portland was sentenced to prison for voting under the name of his dead brother and deceased son. Secretary of State spokesperson Andrea Cantu Schomus says they first suspected Keaton of the voter fraud in 2009. During that investigation they found other layers of deception. "We've actually turned our allegations over to the Department of Justice. It started with voter fraud, but the investigation uncovered some other illegal activity. In addition officials discovered he was also fraudulently receiving federal benefits." Last September Keaton pleaded guilty to federal charges for collecting social security, food stamps and Medicare benefits in the name of his deceased brother.
