Authorities say the longest-serving prosecutor in South Carolina has been found guilty of driving under the influence.

Local media report a magistrate fined Lexington County prosecutor Donnie Myers more than $1,000 Tuesday, rather than impose a 30-day jail sentence.

Myers announced his retirement last year, weeks after troopers reported finding his car crashed into a utility pole and the prosecutor smelling of alcohol. Myers said he'd been run off the road, but a trooper's dashcam video showed him struggling to complete sobriety tests.

His lawyer says Myers was held to a higher standard because of his role as solicitor. Myers took office in 1976.

He had pleaded guilty to driving while impaired in 2005 and served a year of probation.
