LAPLACE — A former patrol shift lieutenant commander in the St. John the Baptist Parish Sheriff’s Office is facing sentencing next month after being found guilty of theft and malfeasance.

According to the St. John Clerk of Court’s Office, Keith Carroll, 35, was found guilty April 18, with Judge E. Jeffrey Perilloux setting sentencing for May 22.

According to the Clerk’s Office, a jury unanimously found Carroll guilty of theft under $750 and malfeasance in office.

Carroll was terminated and arrested shortly thereafter in January 2016 after police said he used a Sheriff’s Office gas card for personal gain.

Authorities did not initially release how much money was charged or where it was charged, saying at the time that detectives believed the suspect only used the card for personal use one time.

A resident’s complaint led to an Internal Affairs investigation, which revealed Carroll used the fuel card to fuel a non-department vehicle, Sheriff Mike Tregre reported at the time of arrest.

Carroll was employed with the Sheriff’s Office for seven years.

He was fired Jan. 13, 2016.
