LOUISVILLE, Ky. (WHAS11) – A Louisville Metro Corrections officer finds himself out of a job after a 5-month investigation revealed he used racist, derogatory language towards another employee.

The investigation dates back to February after 9 co-workers of former Officer Christopher Boog told jail officials he used a racial slur in conversation when describing a former female employee.

In a scathing letter written by Director Mark Bolton, he says Boog told officials he used the “less offensive” version of the word instead of the racial version to a white female to justify that it couldn’t be viewed as that.

Bolton says when Boog was reprimanded and counselled about the use of the word, he took to his social media page stating “these (expletive) people here have delicate sensibilities” and coupled the post with a video of how whites say the word to African-Americans.

Bolton says it was one of many reports involving Boog’s questionable behavior.

In another incident addressed in the letter, Bolton said during the celebration of Black History Month in February, he allegedly told employees he celebrated “James Earl Ray month.” Ray was responsible for the assassination of prominent Civil Rights leader Dr. Martin Luther King Jr.

Boog denied the claims but Bolton said he found the report to be “credible.”

Bolton said he found Boog’s conduct troubling and said it violates the standards of conduct, especially when the LMDC community is 20 percent African-American and much heavier with jail operations.

He said the in-population at Metro Corrections for 2015 was more than 40 percent African-American.

“Whether joking or jesting, your comments suggest racial bias or prejudice against the very citizens that you interact with every day of your job,” he said in the letter.

Throughout Metro Corrections Code of Ethics and Metro Government’s Policy of Ethical Conduct, all members of the criminal justice community are expected to be “honest and serve with integrity to maintain the reputation of the profession.”

Bolton said he believes that speech and inflammatory speech are protected under the First Amendment but doesn’t believe Boog’s comments “expressed an opinion on a matter of public concern.” He went on to say the comments made by Boog impaired the harmony among co-workers and has caused them to “retract their loyalty” to him, leaving him vulnerable in a jail environment.

Bolton closed out the letter saying Boog compromised his own ability to safely perform his job responsibilities.
