St. Louis, MO  (KTRS)  St. Louis Police Chief Sam Dotson is facing another discrimination lawsuit over a job promotion.

A suit was filed Tuesday on behalf of Major Rochelle Jones, alleging she was passed up for the position of lieutenant colonel based on gender discrimination. “I didn’t do it for myself. I did it for the younger police officers that are coming up, the men and women, the police officers who put in their time, they actually go to school, the better themselves, they are looking for advancement.” said Jones during a news conference.

Jones claims she has more education, seniority, and scored higher on the test than Ronnie Robinson, a black police officer who was promoted to the position in 2015.  This lawsuit comes on the heels of Major Michael Caruso, who is white, filing a racial discrimination suit last week over this same promotion.

The St. Louis Police Department has only promoted one female to the rank of lieutenant colonel in it’s 208 year history.

The City of St. Louis is also named in the suit. Jones’ attorneys are asking for a jury trial.

KTRS has reached out to the St. Louis Police Department for comment and is still awaiting a response.
