A man accused of making bomb threats has pleaded guilty to the crimes.
Officials say Frederick Purvis, 42, used a false name to send e-mails from several hotels to media agencies saying the locations would be "blown up" between November 14 and November 16.
According to FBI officials, Purvis had several targets on his list, including four bridges over the Ohio River, Argosy Casino in Indiana, the Cincinnati/Northern Kentucky International Airport and Paul Brown Stadium.
Thursday, Purvis pleaded guilty to one count of making a bomb threat in the Southern District of Ohio and one count of making a bomb threat in the Eastern District of Kentucky.
As a part of the agreement, Purvis admitted to driving to a hotel in Fairfield on November 13, 2008 and creating an email account with a fake name and using it to send the threats. He also admitted to creating another email account at a hotel in Erlanger and emailing a threat to the TSA about a bomb at CGV airport.
Purvis faces up to 10 years in jail and a fine of $250,000. A date for sentencing has not been set, and Purvis will remain in custody until he is sentenced.
