Four Vicksburg police officers have been promoted, two from lieutenant to captain and two from sergeant to lieutenant, Chief Walter Armstrong said.

“All of these people who were promoted are doing a good job, and each has been on the job for 20 years or more,” he said, adding that uniform division commander Davey Barnett has been with the department for 28 years, and criminal investigations chief Bobby Stewart for 25. Both men were promoted from lieutenant to captain.

Detective Sgt. Sandra Williams and traffic division commander Sgt. Jackie Johnson were promoted to lieutenant.

The promotions were approved by the Board of Mayor and Aldermen in an executive session Monday. North Ward Alderman Michael Mayfield said the money for the promotions were included in the fiscal 2011-12 budget.

Each officer receives an annual raise of about $4,014.

Stewart’s salary increased from $47,133 to $51,147, while Barnett’s pay increased from $44,346 to $48,360. Williams’ pay increased from $46,571 to $50,586, while Johnson’s pay went from $40,040 to $44,054.

Police officers are under civil service and did not receive the 3 percent pay raises that other city employees received in 2010. Officers receive periodic step increases and raises if they are promoted or receive special training.

Armstrong said the promotions were the first promotions to captain or lieutenant in nine years.

He said Barnett is replacing Capt. Mark Culbertson, who retired in February 2010. He said Culbertson was also investigations commander and later transferred to the uniform division, leaving the captain’s spot in investigations vacant. Stewart, Armstrong said, was promoted to chief of investigations as a lieutenant.

He said Williams fills the lieutenant’s spot vacated by Stewart’s promotion, adding that Williams is second in command in investigations.

“Traditionally, the traffic division has been commanded by a lieutenant,” Armstrong said about Johnson’s promotion. “We had that vacancy there for some time.”
