Denton County Sheriff's investigators on Monday were awaiting blood tests on a teenager who died early Sunday following a party near Argyle where alcohol was available, officials said.
Austin Durant, 18, of Justin, was pronounced dead at 8:50 a.m. Sunday at Presbyterian Hospital-Denton, according to the Tarrant County medical examiner's office.
The party was held at a mobile home in the 400 block of Cactus Drive, south of Argyle, according to reports.
Meanwhile, however, deputies arrested James Reynolds, 21, on a charge of purchasing or furnishing alcohol to a minor, said Tom Reedy, sheriff's spokesman.

"There were several people who were involved and who were questioned," Reedy said. "(Reynolds) was the only one over 21. From information we got from witnesses, he was the one who bought the alcohol."
Reedy said, however, on Monday morning that it was premature to say Durant died of alcohol poisoning. That's why blood tests were being done to help determine how he died, Reedy said.
"According to witness statements, there was a big drinking party and early next morning someone tried to wake (Durant) up," Reedy said.
When Durant didn't respond, his friends called 911, Reedy said.
Operators instructed them how to give CPR, he added, which they did until paramedics arrived.
Reynolds was still being held Monday morning at the Denton County Jail, according to official records.
The charge of purchasing or furnishing alcohol for a minor is a Class A, misdemeanor, punishable by up to 180 days in jail and a $2,000 fine.
Bond for Reynolds was set at $10,000, according to jail records.
