The final minutes that led up to a horrifying crash will change the lives of an SUV full of teenagers, investigators said.

Burned pieces of the SUV and debris told the story of how serious this crash was, an impact so forceful the single car involved went up in flames. The seven teenagers who were riding inside were ejected.

The driver and one passenger were killed. The rest remain hospitalized, at least two in critical condition.

"These kids are going to have, at best, some lifelong reminders that this was a bad night," said trooper Howard Dickinson, public resource officer with the Kansas Highway Patrol.

The night started in a Walmart parking lot. A Roeland Park police officer was called to check on a suspicious vehicle driving around the parking lot at 3 a.m. Sunday when the Walmart was closed.

When the officer approached, Dickinson said it was pretty obvious that they immediately began to run at the first opportunity that they could.

"They weren't going to stop," he said.

Investigators say the Roeland Park police officer involved in the chase did not initiate it, and did not even have a chance to speak to the teens before they took off. Dickinson said when the SUV took off the vehicle was going well over 70 miles an hour.

The officer followed at a distance down Roe Lane to an Interstate 35 overpass.

Investigators said the driver lost control, hit a pole, then spun around hitting a second pole, and actually lifted off into the air. The vehicle then continued to spin, and the centrifugal force pushed all seven of the passengers out of the car.

The driver, Alexis Medina, 18, and his passenger Karla Robledo, 18, both of Kansas City, MO, died in the crash.

"With none of them being buckled in, and this kind of a crash, they stood very little chance of being able to stay inside the vehicle," Dickinson said.

Gabriela Villa-Paralta, 19; Damian Franklin, 17; David Solis-Lopez and Eduardo Chacon Solis, both 16; and Lorenzo G Solis, 15, were all taken to area hospitals.

Investigators are still working out why they took off so fast, but they did find alcohol at the scene.

Crushed beer cans, now littered between broken pieces of the car and cracked CDs, were all reminders of the everyday lives changed forever in a single moment.

Because the driver was killed in the crash, troopers say it is unlikely that there will be any charges filed, but the investigation continues.
