It begins with the sound of screeching tires and then impact and shattering glass.

On Sultana High School's Jay Reed Field, a gray tarp is removed from the track, uncovering a light gray sedan slammed into the side of a blue minivan. A bloody teenage girl is sprawled across the car's crumpled hood, unmoving.

It was not going to be a run of the mill assembly for Sultana's juniors and seniors on Thursday morning.

There is quiet laughter and comments from the juniors and seniors assembled in the grandstand at the beginning of the "Every 15 Minutes" assembly. The name refers to the rate at which drunk driving kills people on American roads every day.

"I'm sure there are those who, you know, don't listen, but I've also heard comments from students who come to me later and said 'I was in a scenario where there was drinking and I chose not to drive because of what I saw,'" said Stan Clark, Sultana's activities director, who organized the assembly.

The voice of the 911 dispatcher calling for an ambulance came over the loudspeakers. A moment later, a pair of California Highway Patrol vehicles came racing up, and were greeted by a weeping and bleeding woman emerging from the minivan. Four injured people, from both cars, milled around as the CHP officers investigated the scene. A San Bernardino County Fire Department truck pulls up moments later.

"Unfortunately, and all too often, it is not the drunk driver who is injured or killed in an alcohol related crash," the narrator announces over the loudspeakers. "Such is the case here today.  Although being innocent of drinking and driving, the life of Alyx Yankaskas has now been taken. Alyx died almost instantly at the time of the crash."

The earlier comments from the audience are muted as Yankaskas' obituary is read over the loudspeakers.

Meanwhile, fellow passenger Scott Major is strapped to a gurney by firefighters who will transport him to the hospital. Meanwhile, other firefighters start up a small gasoline-powered engine to power a hydraulic spreader -- so-called "jaws of life" -- to free Yankaskas' boyfriend Hunter Schneider from the back of the sedan so that paramedics can evaluate his condition.

The audience is quiet now.

The graphic nature of the accident -- including its victims -- are decided by the students involved in the assembly, which is held every other year, for a new crop of juniors and seniors.

"There's usually a select group of students who sit down with us and develop the story," said Clark. "We want it to be from a student's perspective and be believable."

The assembly brings together community businesses and organizations, including the California Highway Patrol, San Bernardino County Fire Department, Victor Valley Mortuary features donated wrecks from G&M Towing.

"The fire department's been really good about it," said Clark. "They virtually don't need any practice, because they're just doing what they do."

Schneider is freed from the back of the sedan and strapped to a gurney as CHP Officer William Ocegueda administers a field sobriety test to Sultana junior Brooke Turner, the driver of the sedan that t-boned the minivan. As she walks a line in the sand drawn by the officer, Turner tells him she only had two shots of liquor before getting behind the wheel.

As the officer puts the handcuffs on a sobbing Turner, charging her with driving under the influence, the audience is informed that Schneider dies as a result of his internal injuries at the hospital, and Turner is additionally charged with multiple counts of vehicular manslaughter.

Two employees of the county coroner's office peel Yankaskas off the car's hood and put her in a body bag as Turner is placed in the back seat of a patrol car.

After taking care of Yankaskas' body, a coroner's employee heads to the minivan.

"Thankfully, the young couple, who was hit by Brooke's car, did survive," the narrator announces. "However, the life of their young child in the back seat was cut short when it was tragically taken. This experience will haunt the couple for the rest of their lives."

The coroner's employee emerges, carrying an infant car seat covered by a baby blanket, containing a 9-week-old child to a waiting hearse.

You could hear a pin drop at Jay Reed Field.

"The tragedy you have all witnessed could have been prevented had certain participants done one thing: think," the narrator announces. "Think before drinking and driving. Better yet, think before considering drinking at all.  If this would have been the case, we would not be thinking about the death and destruction caused here today. In fact, you all have much more pleasant things to think about, such as prom, graduation, grad night and college. This is certainly not the way you want to remember your high school experience. Now, for the remainder of Brooke's life, all she will know is the agony of what she has done and a place to dwell on it - inside prison."

The assembly ends with a radio report about the crash by 99.1 disc jockey Jeff Pope and a dedication of Puff Daddy and Faith Evans' "I'll Be Missing You," which plays as the students file out.

"These aren't experiences that kids look forward to, but it's really eye-opening for them," said Clark.
