Man pleads guilty to supplying drugs in fatal overdoses
A San Antonio man has pleaded guilty to drug charges related to three fatal and one near-fatal overdoses, U.S. Attorney Jaime Esparza announced Thursday.
Mark Elliot Stool, 67, admitted supplying substances containing combinations of methamphetamine and fentanyl, as well as methamphetamine and heroin, to four people between August 2021 and March 2022.
Police stopped him in June 2022 as he drove his Tesla from the home he shared with his elderly mother on Lockhill-selma Road. He was found to be in possession of a substance that tested positive for methamphetamine and fentanyl, and arrested.
At a hearing Wednesday, Stool pleaded guilty to three counts of distribution of a controlled substance resulting in death and one count of distribution of a controlled substance resulting in serious bodily injury.
One victim was a male friend who died in February 2022 at Stool’s home, according to court records. Stool told federal agents he went to sleep and woke to find his friend had died.
Stool also told agents about two other deaths — of a 25-yearold woman in March 2022 and a 66-year-old man in August 2021 — and the January 2022 overdose of a 23-year-old woman who survived after being given Narcan, a criminal complaint affidavit said.
The people were identified after further investigation, but they are only identified in court records by their initials or general descriptions.
Stool is scheduled to be sentenced on July 17 and faces 20 years to life in prison.
His arrest surprised observers at the time because his parents were both retired doctors, and he had moved in with his mother in that upper middleclass area. His father had passed away.
Records show Stool had previously fallen into illegal drug use. He served deferred-adjudication probation for drug possession in 1997, records show.
The U.S. Drug Enforcement Administration, University of Texas at San Antonio Police Department, San Antonio Police Department, Bexar County Sheriff ’s Office and Castle Hills Police Department are investigating the case.
