Bryan Police believe the three teens involved had been to a sweet 16 party Saturday night, where alcohol was served.
They say the teens were drinking and that ultimately impairment and high speed led to the crash.
Early Sunday morning, Bryan Police say the teens were hanging out in the parking lot, near the Park Meadow neighborhood Pool.
Around 3:30am, an officer responded to calls about a suspicious vehicle.
"When he got down to that area he was approached by a vehicle coming from the opposite direction at an extremely high rate of speed. So much so that the vehicle forced the patrol car to the shoulder to prevent a collision," said Bryan Police Chief Ty Morrow.
Police say the officer turned around near Bowen Elementary to chase the car northeast on Copperfield Drive.
"When he got back up to the last curve right here, he saw the vehicle actually go airborne here at the intersection where the driver lost control of it," said Morrow. "Came back down, hit there, and went airborne again."
From there the car hit one tree in the median, and then another.
"The officer was able to get to the vehicle shortly after the crash. The occupants were still inside," said Morrow. "The front female passenger he initially tried to get out and she was obviously dead from the injuries that he could see. A small fire started. He extinguished his fire extinguisher trying to put the fire out and it was just, he couldn't do it, it was too much."
Three teens died in the accident. Lives lost, police say, to alcohol.
"Based on that investigation we were able to put together that they were involved in alcohol," said Morrow.
When asked if witnesses at the party told detectives they saw the teens drinking, Morrow replied "yes."
Online, friends have changed their MySpace pages to read "Rest in Peace Alex, we love you," for Alex Dickey, of Bryan. Dillon and Gus Benavides are also remembered online.
Bryan Police haven't said how the teens at the party obtained the alcohol, or if anyone has been cited for providing alcohol to minors.
