A woman who tried to swallow pills before being booked into jail on drunk driving charges has been issued a 60-day sentence.The woman, Tiffany R. Greer, 32, of Brentwood, entered guilty pleas before Circuit Court Judge Bart Stanley to charges of DUI, casual exchange of marijuana, possession of drug paraphernalia and tampering with evidence. She was ordered to serve 60 days of a three-year sentence, perform 24 hours public service work, pay $900 and lose her driver license for one year.Her charges come after she was pulled over and arrested for drunk driving. The arresting officer noticed she was acting unusual while she sat in the back seat of his car on the way to jail and told his suspicions to the corrections officers at Warren County Jail.That was why guards were watching her closely after they placed her in a holding cell.
