BROWNSVILLE, Texas (ValleyCentral) — A woman has been sentenced to 30 years for delivering drugs to a Cameron County inmate, which resulted in her death.

According to Cameron County Court records, Brandy Ann Brown Daniels pleaded guilty to murder on Sept. 8. The indictment details that on Oct. 21, 2023, Daniels delivered fentanyl to 25-year-old Jacqueline Barosio while she was in jail, which resulted in her death.

As previously reported by ValleyCentral, on October 12, 2023, Barosio was evaluated for a toothache and was diagnosed with cavities, which were associated with gingival inflammation, also described as swelling/irritation of the gums.

Due to her diagnosis, she was prescribed an antibiotic (Amoxicillin) and a pain medication (Naproxen). A follow-up evaluation was conducted on Oct. 19, and there were no signs of infection. Amoxicillin was continued, and the Naproxen was replaced with Ibuprofen.

Two days later, on Oct. 21, 2023, Barosio was found unresponsive in her cell and was pronounced dead at the scene.

An autopsy report listed her cause of death as acute fentanyl toxicity.

In September 2024, an indictment was issued that describes Daniels as the person who delivered the substance to Barosio, leading to her death.

On Sept. 8, 2025, Daniels pleaded guilty to the murder of Barosio and was convicted to 30 years in prison and given 705 days of jail credit.

On Monday, Cameron County District Attorney Luis V. Saenz stated that, as per the state's 2023 Fentanyl Murder Law, those who knowingly deliver fentanyl and cause a death will face prosecution for murder.

“Fentanyl is not just another drug—it’s a poison taking the lives of our sons, daughters, and loved ones at alarming rates. Let it be clear: if you sell fentanyl and it causes someone’s death, you are a murderer under Texas law," Saenz stated. "You will be charged, prosecuted, and held fully accountable.”

According to the DA, fentanyl is up to 100 times more potent than morphine, and even a trace amount can be deadly.
