Ex-TDCJ officer sentenced for drug smuggling

SMITH COUNTY, Texas (KETK) — A former Texas Department of Criminal Justice (TDCJ) correctional officer was sentenced to 10 years in prison on Thursday after attempting to bring illegal drugs into the prison last year. Diamond Dunn was arrested in August 2025 after she had agreed to meet with an undercover officer at a CEFCO gas station.

During the encounter, authorities said Dunn took $2,500 and around 71 grams of methamphetamines from the undercover cop with the purpose of bringing the drugs to the TDCJ Boyd Unit, where she worked. Dunn was later charged with bribery and the manufacture/delivery of a controlled substance. In April, Dunn was found guilty of bribery and was sentenced to 10 years in prison on Thursday by the 175th Smith County District Court.
