Sooner linebacker Austin Box did not have prescriptions for any of the six powerful drugs found in his system after he died May 19 from a toxic mix of the drugs, El Reno Police Chief Ken Brown confirmed Wednesday.
Brown said state drug enforcement officers checked the drugs found in Box's system against the state's prescription-monitoring database and found no matches for any prescriptions issued to Box.
That would indicate the five types of painkillers and the anti-anxiety drug alprazolam that Box consumed were not obtained through the legal prescription process, Brown said.
The state medical examiner's office determined Box died from a toxic mix of oxymorphone, morphine, hydrocodone, hydromorphone, oxycodone and alprazolam.
The El Reno Police Department is continuing its investigation into the source of the drugs, the police chief said.
Box's parents told The Oklahoman on Monday they did not believe their son had prescriptions for any of the medications.
Box, who was expected to be a starting OU linebacker this fall, died May 19 in El Reno after spending an evening playing video games with a friend there.
