DENISON, Tex. -- Denison police officials say drugs may have played a part in Sean Fryar's death.
The Dallas County Medical Examiners office ruled Fryar’s death as an accidental drowning due to the effects of amphetamines.
The report does not state what kinds of amphetamines were in Fryar's system nor does it explain the role they may have played in his death.
The report also shows Fryar had a blood alcohol content of 0.08.
"The autopsy results are consistent with a lot of the information that we have gathered during the investigation."
Fryar disappeared April 15th, the day after the Denison High School prom. On April 19th, two fisherman on Waterloo Lake noticed Fryar's body floating in the water.
Police are still investigating how Fryar ended up there but say the autopsy gives them some clues..
"Anytime you mix any substance together it’s always dangerous and by themselves, they're dangerous, and when you mix them it just magnifies that," said Lt. Mike Eppler of the Denison Police Department.
Officials are not releasing how Fryar came in contact with the amphetamines or if any charges will be filed.
They say it's too soon to rule anything out.
"We don’t ever close the doors until we close a case. We keep all of our options open in every case we work until it’s finally closed down."
Police say they will continue to question everyone involved in the investigation and are looking into how Fryar got the drugs.
Sean Fryar was 17 years old.
