St. John the Baptist Parish’s recently elected district attorney and three parish judges took the oath Monday for new six-year terms.

District Attorney Bridget Dinvaut was the only nonincumbent sworn in, joining re-elected Judges Mary Hotard Becnel, Madeline Jasmine and Sterling Snowdy. The hourlong ceremony was held before a packed crowd at 40th Judicial District Court in Edgard.

Dinvaut, 53, is a former assistant district attorney who also maintained a private legal practice in LaPlace. She finished second in October’s primary election to former District Attorney Tom Daley, but Daley later withdrew from the runoff for health reasons, effectively electing Dinvaut.

During the ceremony, she described Daley as “a friend and a mentor,” calling him “an important part of my life.”

A host of state and local politicians attended the ceremony, including Louisiana Attorney General Buddy Caldwell.

“The election is over,” Caldwell said. “Now the work begins.”

Dinvaut, a Democrat, graduated from Southern University at New Orleans and the Southern University Law Center.

She worked in the St. John Sheriff’s Office from 1986 until 1994, then spent eight years as a federal law enforcement officer in Louisiana and Florida. She began practicing law at the New Orleans-based firm of Lemle & Kelleher in 2005 before joining Daley’s office in 2010.
