A teacher has been “relieved of her teaching duties” after posting a racist Facebook rant in response to recent events at a McKinney, Texas, pool party, according to a statement from Frenship Independent School District.

Karen Fitzgibbons was a fourth-grade teacher a Bennett Elementary school of Frenship ISD in Wolfforth, Texas. On Tuesday, she posted an article to her page about Eric Casebolt, a police officer who recently resigned after being involved in a racially charged incident last Friday. Casebolt, who is white, was caught on tape throwing a black, bikini-clad teenage girl to the ground when responding to reports of a disturbance at a community pool. He also pointed his gun at other youths.

“This makes me ANGRY!” reads the post from Fitzgibbons, referring to Casebolt’s resignation, according to Texas outlet the Lubbock Avalanche-Journal. “This officer should not have to resign. I’m going to just go ahead and say it…the blacks are the ones causing the problems and this ‘racial tension.’ I guess that’s what happens when you flunk out of school and have no education.”

The post continues, “I’m sure their parents are just as guilty for not knowing what their kids were doing; or knew it and didn’t care. I’m almost to the point of wanting them all segregated on one side of town so they can hurt each other and leave the innocent people alone. Maybe the 50s and 60s were really on to something. Now, let the bashing of my true and honest opinion begin….GO! #imnotracist #imsickofthemcausingtrouble #itwasatagedcommunity.”

The post has since been deleted.

The statement from Frenship ISD says the district “is deeply disappointed in the thoughtlessness conveyed by this employee’s post. We find these statements to be extremely offensive, insensitive, and disrespectful to our Frenship community and citizens everywhere. These comments in no way represent the educational environment we have created for our students.”

“Employees are held to the same professional standards in their public use of electronic media as they are for any other public conduct. This recent conduct was unacceptable,” says the statement from the district.

Spokespeople from Frenship ISD did not respond to further requests for comment.

Fitzgibbons later issued an apology, according to local outlet KCBD-TV.

“First, to anyone, of any race, that I have offended, I sincerely apologize. That was not my intent. I let my emotions get the best of me, and instead of taking a deep breath, vented in an inappropriate way. I am truly sorry,” it says in part.

The apology goes on to say that Fitzgibbons teaches her students to treat others with dignity, and she is now “ashamed” of her previous Facebook post.
