Hundreds of leads are pouring in to the Minnesota State Patrol following a road-rage accident that killed a St. Paul, Minn. teenager.

Fifteen-year-old Samantha Kelly died early Saturday morning when she was partially thrown from a Jeep riding with six other teens on their way home from a camping trip.

Her 16-year-old boyfriend, Alexander Schaenzer, was badly hurt and is in a drug-induced coma in the hospital. The other friends that were in the Jeep are recovering at home.

The accident happened on Interstate 35E in White Bear Lake, Minn. Investigators are looking for a dark-colored sedan that cut in front of the teenagers and slowed down before taking off.

The state patrol admits they are "looking for a needle in a haystack" but say a few possible leads have come in from people who saw a car in the area that fit that general description. However, nothing has led them to the right car yet.

The chief investigator said his phone has been ringing off the hook since Sunday night when Samantha's family and friends put out a plea for information. They gathered to remember the rising junior at Highland Park Senior High School.

"I don't hate you. I do hate the fact that you left the scene, not caring what had happened. I just want you to come forward and face what has happened," said Laena Kelly, Samantha's mother.

The State Patrol is looking for a dark blue or black car in this case, possibly an Audi or a Nissan.

They also said a similar incident happened 12 hours earlier on the same road. That car had a Minnesota license plate similar to NNY 545. It was a black or dark blue newer model passenger car with chrome trim. The driver was a slender man with shoulder-length brown hair with highlights. The State Patrol thinks these cases might be connected.
