Drug dealer sentenced to more than 28 years for selling heroin that killed Southlake teen

A Fort Worth heroin dealer was sentenced on Thursday to 340 months in federal prison for selling the drug that killed an 18-year-old in her Southlake home in December 2017.

Michael Dasean Robinson, 33, was sentenced to more than 28 years by Senior U.S. District Judge John H. McBryde in a federal courtroom.

Robinson — who went by the street name “Tight” — sold $40 worth of heroin on the night of Nov. 30, 2017, to Reed Bartosh, 18, of Colleyville, and his girlfriend, Brianna Flood, 18.

Flood died a few hours later from the heroin, according to officials with the Tarrant County Medical Examiner’s Office and federal court documents.

“This woman’s untimely death was tragic — and preventable,” said U.S. Attorney for the Northern District of Texas Erin Nealy Cox in a news release. “Even as we mourn the many lives lost in the opioid epidemic, we are determined to hold those who peddle these deadly drugs accountable.”

Robinson had pleaded guilty in April to the federal charge of conspiracy to possess a controlled substance (heroin) with intent to distribute.

“The sentence sends a message to drug dealers,” said Special Agent in Charge of the Drug Enforcement Administration’s Dallas Division Clyde E. Shelley Jr. “Drug dealers will be held accountable for their customers’ overdose deaths.”

Heroin deaths have been on the increase for years, according to a study by the Department of Justice and the Drug Enforcement Administration. A 2018 National Drug Threat Assessment report showed there were 2,089 deaths in 2006 compared to 15,469 in 2016.

The Fort Worth man was a drug dealer from 2017 until January 2019, according to court documents.

Local, state and federal authorities began an investigation after Flood’s death.

According to a criminal complaint filed in January, after her death, undercover officers posing as Robinson’s clients bought heroin and cocaine from him and an associate.

“Can you do 140 b and 50 g?,” an undercover officer texted Robinson, referring to heroin and cocaine.

“Yeah,” Robinson responded. “Hit me up.”

At Robinson’s direction, according to the complaint, his associate delivered plastic baggies containing heroin (commonly referred to as “boy,” or “b”) and cocaine (commonly referred to as “girl,” or “g”) to an undercover officer parked in the driveway of a Dallas residence in exchange for cash.

Robinson was arrested in November 2018. Armed with a search warrant, investigators seized Robinson’s cell phone. A forensic analysis concluded Robinson had 100 heroin customers, 80 cocaine customers, 25 crack cocaine customers and 25 methamphetamine customers.
