SAN DIEGO - A sheriff's deputy who got into a struggle with police officers when they arrested her on suspicion of driving while intoxicated outside a Carmel Mountain fast-food restaurant pleaded guilty Thursday to misdemeanor charges of DUI and disturbing the peace.

Diedre R. Quenell, 43, was immediately sentenced by Judge Robert F. O'Neill to 10 days of public work service and ordered to pay a fine of $2,064, according to Gina Coburn of the San Diego City Attorney's Office.

Officers responding to a report of a woman driving erratically in a parking lot near the McDonald's in the 11900 block of Carmel Mountain Road took Quenell into custody shortly after midnight last Aug. 15, according to San Diego police.

Police said Quenell was uncooperative with the officers as they detained her and was taken to jail. She was later released on $2,500 bail.
