AMARILLO, Texas — An Amarillo drug dealer who sold a fatal dose of heroin has been sentenced to 20 years in federal prison, federal prosecutors announced yesterday. Three other co-defendants were also sentenced to a combined 20 years.

58-year-old Cynthia Marie Carrasco previously pled guilty in the case to possession with intent to distribute heroin resulting in death. She was sentenced to 20 years in federal prison.

On April 19, 2019, the Amarillo Police Department and Amarillo Fire Department responded to an Amarillo hotel for a suspected heroin overdose. There, they discovered a 33-year-old victim deceased.

The deceased victim had been staying at the hotel with 37-year-old Jeffrey Michael Smith who admitted to purchasing heroin from Carrasco for a period of time.

"Smith admitted that he purchased the heroin for his acquaintance used shortly before her death from Carrasco," read a statement from the U.S. Attorney's Office of the Northern District of Texas.

"During a non-custodial interview with Carrasco at her home, she admitted that she knew Smith and had previously sold him heroin," continued the statement. "Carrasco stated that she repackaged heroin into smaller quantities for sale."

"In a subsequent interview, Carrasco admitted that her heroin had killed the victim on the night of April 19, 2019."

Investigators discovered evidence on Carrasco's cell phone which indicated she was purchasing her heroin supply from 64-year-old Andrew Olguin and that 26-year-old Austin Ryan Potts had delivered heroin to individuals for Carrasco.

For their roles in the victims' death, co-defendants Potts, Olguin, and Smith were sentenced to five, 10, and 10 years in federal prison, respectively.
