'Multiple false statements' According to the report, the inspector general's office found that human resources assistant director Pamela Cabell-Edelen had tried to get her daughter hired to various positions, including changing a vacancy announcement to improve her chances.
Her daughter was hired as secretary to facilities director Edward Hamilton in November 2009.
The report also charges that Ms Cabell-Edelen, who retired from the department last year, made "multiple false statements" to investigators.
Shortly after, Mr Hamilton began advocating for his son's hiring to a position within the division.
The investigation found two other justice management division employees improperly advocated for the hire of each other's family members.
Several others also discussed hiring family members.
Human resources director Rodney Markham was found "negligent in his duty to exercise effective oversight", especially given the two prior investigations into hiring practices.
