Vikings safety Willie Offord pleaded guilty to drunken driving Tuesday in Hennepin County District Court. District Judge Bruce Peterson ordered Offord to pay a $600 fine and perform 32 hours of community service. Offord pleaded guilty to misdemeanor fourth-degree drunken driving. Offord was stopped by the State Patrol April 18 on Interstate 394 in Golden Valley. His blood-alcohol level was not available at that time. His attorney, David Valenti, said Offord challenged the legality of the stop, but Peterson rejected it.
