FLEMING ISLAND, Fla. – A Florida high school student was suspended for 10 days and could face expulsion after posting an image of two black classmates to Craigslist in an ad for “two slaves for sale.”

The Craigslist post feature a picture of two black girls sitting at desks with the headline “Two slaves for sale – $470,” and was tagged to the location “Fleming Island Plantation.”

Officials at Fleming Island High School confirmed that a male senior was responsible for posting the ad was suspended for 10 days, but they did not identify the student. The school’s principal is recommending that the Clay County school board transfer him to an alternative school. The school board is now reviewing the recommendation, but could also expel the student, WJXT reports.

The ad, which has since been removed from Craigslist, offered “two healthy negro slavegals for sale.

“Good condition and hard work ethic!” it read. “If you need another pair of hands around the farm/house, you’re in luck.”

“Clay County District Schools was made aware of an inappropriate post on the internet last night. The Fleming Island High School administration immediately began to investigate this concern in order to identify the individual who posted this inappropriate picture,” district spokeswoman Nicole Snyder said in a prepared statement to Clay Today.

“After launching an in-depth investigation, administrators have identified the student and will be taking actions as outlined in our Code of Student Conduct.

“We do not tolerate this type of behavior and we are disheartened that any of our students would be subject to discrimination,” Snyder continued. “Fleming Island High School administration and district leadership are working together to create a school-wide plan of action to strengthen the climate and culture while celebrating the school’s diversity.”

Fleming Island senior Skye Fefee, one of the girls in the photo, told WTVR she learned about the picture from a friend who forwarded the ad to her on Snapchat. By then, many of her classmates had already seen the ad.

“I feel disturbed by it,” she said. “It shows me that there is still a lot of racism in this school.”

“I was mind-blown by it, surprised this stuff is still happening in 2017,” her friend, Autumn Olson, told CBS 47. “It went way too far, it shouldn’t have been a joke at all.”

Several folks who commented about the situation online seemed to agree.

“There’s nothing funny about this. These kids are in school trying to learn, and he’s taking stupid pictures of them saying stupid stuff,” Sabrina Boawman posted to Facebook. “Expel him … and see how they feel.”

“This is sad, some kid undoubtedly thought it was cute or funny. There are people of all colors in slavery today,” Carolyn Thornton added. “I hope that the parents of this kid teach him about the real world.”
