A former Gatesville Independent School District football coach turned himself into authorities at the Coryell County Sheriff’s Office on Nov. 22, pursuant to a warrant for arrest.
Aaron Jay Mueller, 26, was charged with the delivery of a controlled substance.
The investigation encompasses information and allegations that arose in late July regarding a GISD coach/teacher’s aide accused of providing performance-enhancing drugs to student-athletes.
The investigation was completed in October and was presented to the Coryell County grand jury Nov. 16. The jury returned an indictment on a charge of delivery of a controlled substance. Mueller was arrested on a charge of knowingly manufacturing or delivering/possessing a controlled substance with intent to deliver drugs in an amount of less than 28 grams.
The crime is a felony, punishable by confinement in a state jail for a term of not more than two years or less than six months, according to sentencing guidelines.
Mueller posted $5,000 bond shortly after being arrested and was released.
On July 17, a Gatesville varsity coach met with Gatesville ISD Athletic Director Kyle Cooper to inform him of a rumor reported by a concerned resident.
The coach said he heard a junior high school teacher and coach was allowing student-athletes to come to his residence for what was described as nutrients.
After hearing the story, Cooper contacted school Superintendent Eric Penrod to tell him about the rumor.
Following a short meeting, the two administrators called Mueller about the allegations.
Mueller met with Cooper two days later and admitted allowing his residence to be used for the delivery location for what he called nutrients. The coach said they were high-level nutrients from a guy in Houston that cost $100 per vial.
Two students came to Cooper on July 19 to admit to participating. Mueller submitted his letter of resignation the same day. Later, six students said they used the coach’s residence to receive what would later be described as injectable testosterone.
Until recently, Gatesville Police Department officials have not released information about the content of the vials.
GISD officials said they learned the coach had injected the six student-athletes with alleged injectable testosterone during June. Injecting testosterone is not a crime, unless there was not a prescription.
One of the students had developed a boil on the injection site and a parent of one of the students said she was a registered nurse and would provide the administration of the shots.
The six student-athletes were suspended for a month during the summer. All six tested negative for performance-enhancing drugs, following the suspension in late August.
