ADAMS TWP — The decision to jump "Blind Hill" resulted in the grisly deaths of two young women and a lifetime of horrid memories for four other youths.

Police have completed the investigation into the July 13 one-car accident on Plains Church Road in Adams Township that claimed the lives of Madeline Lind and Karisa Samuels, both 17, and injured the four other girls in the car. All of the vehicle's occupants are from Cranberry Township.

Survivors who were in the 2004 Saturn Vue, a small sport utility vehicle, told investigators that after an evening of driving around, Lind turned onto Plains Church Road from Callery Road to carry out their tentative plan to jump "Blind Hill." One survivor said all five passengers were cheering Lind on, so the teenager "floored it," according to the police report.

Crash reconstruction officers concluded the westbound vehicle was in the middle of the road right before it crested the hill and went airborne for more than 66 feet. The vehicle, owned by Lind's parents, careened 205 feet as Lind tried to get it under control before crashing into a tree.

The impact sent the SUV spinning clockwise until it began to roll over, landing on its driver's side. The vehicle then slid on its driver's side for 55 feet before hitting a hillside, which caused it to roll onto its passenger's side.

The SUV came to rest in that position 360 feet from the crest of "Blind Hill."

Lind was still strapped into the driver's seat and Samuels was found strapped into her seat directly behind Lind in the back seat.

Passenger Karisten Brown, who had just turned 14, was found with her legs under the vehicle. She suffered major injuries and was flown to UPMC Children's Hospital in Pittsburgh.

The other three passengers, Stephanie Gregory, 13; Krista Suave, 16; and Ashley Bonazza, 15; suffered only minor injuries, but witnessed the carnage at the grisly scene.

"It's really sad," said Adams Township police Assistant Chief Ed Brooks. "It's senseless."

Investigators calculated the vehicle's speed to be between 69 and 75 miles per hour when it went airborne. The report said the vehicle dropped 5 feet, 7 inches from its highest point.

Chris Bonazza of Cranberry Township said her daughter received stitches on her left knee and continues adjustments at a chiropractor. Bonazza said the start of the school year helped Ashley's state of mind.

"She is still not driving yet, but we're getting through that," said Bonazza.

She said Ashley and either Gregory or Suave dragged Brown partially out of the wreckage before police arrived. Even though her mother resisted, Ashley insisted on seeing the police report, which contains graphic details recorded by police at the scene.

"She said 'Mom, I've seen it all. There's nothing in there that I didn't see,'" recalled Chris Bonazza.

"It's just devastating," she said.

Police said alcohol or drugs were not involved in the crash.
