Commissioner of Public Safety Albert Santa Cruz said Friday that DPS' investigation is complete.
He says names of those disciplined won't be released because the department considers the discipline a personnel matter.
A news release from the DPS says three of the 14 chose to retire and the remaining 11 were demoted, suspended and reassigned.
Santa Cruz says all 14 acknowledged their actions were inappropriate.
Gov. Haley Barbour announced the DPS investigation in late August. It centered on Highway Patrol promotions examinations that were given in mid-August.
