Court documents filed Thursday say 39-year-old Juan Jose Ontanon-Espinoza faces a federal drug charge and was taken into custody after he gave more than 6 pounds of heroin to a confidential source for the Drug Enforcement Administration.

The agent reports investigators found about 72 pounds of heroin at the house, along with mail addressed to Ontanon-Espinoza. His defense attorney did not immediately return a message seeking comment.

Sentencing is just around the corner for another North Texas who pleaded guilty to her role in selling the heroin that caused a young woman’s overdose death at a McDonald’s restaurant in Farmers Branch in June 2016.

Nancy Pineda, of Farmers Branch, pleaded guilty to one count of conspiracy to possess with the intent to distribute a controlled substance. Pineda has been in custody since the time of her arrest in October 2016. Sentencing is scheduled for January 11, 2018.
