DUNCANVILLE, Texas (AP) — A Dallas-area school district has suspended a teacher over what administrators call “reprehensible” and racially charged tweets about the killing of a black Missouri 18-year-old by a white police officer.

Duncanville Independent School District trustees will meet Friday, and could fire Vinita Hegwood (HEG’-wood).

Hegwood, who is black, taught English at Duncanville High School prior to the tweets posted Friday with expletives and derogatory references to whites and blacks.

A publicly listed phone number for Hegwood couldn’t be found Wednesday.

The school district says Hegwood met with district officials Monday and was suspended without pay pending discharge. In a statement, the district said Hegwood’s personal social media account contained “reprehensible personal opinions.”

Michael Brown was unarmed when he was killed Aug. 9 in Ferguson, Missouri, leading to ongoing community unrest.
