DALLAS (CBSDFW.COM) – A Farmers Branch woman was arrested late Friday evening on a federal criminal complaint stemming from her allegedly selling heroin that caused a young woman’s overdose death at a McDonald’s restaurant in Farmers Branch in June.

The complaint charges Nancy Pineda with conspiracy to distribute heroin. Pineda made her initial appearance in federal court Monday afternoon.  The judge ordered she remain in custody pending a detention hearing set for Thursday, November 3.

“This is yet another tragic example of a young life cut short by heroin,” said U.S. Attorney Parker. “You have my word that every time someone dies from a drug overdose in this district, my office will do everything in our power, working with our law enforcement partners, to identify and prosecute those who sold the drugs. We’re going to hit this problem, and we’re going to hit it hard.”

According to the affidavit filed with the complaint, on June 8, 2016, around 9:45 p.m., a woman was found dead in the bathroom of a McDonald’s restaurant located on Valley View Lane in Farmers Branch. Police suspected the victim’s death was the result of a heroin overdose. This was confirmed by the Office of the Medical Investigator that determined the victim’s cause of death was due to the toxic effects of heroin and ethanol.

According to a news release Monday from the U.S. Attorney Northern District of Texas, the investigation revealed that on June 8, 2016, at 7:00 p.m., the victim negotiated, in text messages, to buy a “dub” and a “point” from an individual, later identified as “A.J.” A “dub” is slang for .20 grams of narcotics, and a “point” is slang for a syringe.

The text conversation concluded at 7:45 p.m. when the victim texted, “we down the street.

A search warrant of A.J.’s cell phone revealed text conversations between A.J. and an individual listed in his phone as “Nina,” who was later identified as defendant Nancy Pineda, a known heroin dealer with whom law enforcement was familiar because of previous narcotics investigations.

Law enforcement confirmed that Pineda knew the victim and had sold heroin to her on a regular basis in the past.
