PINE TWP, Mercer County — A teenager who graduated from Grove City High School less than a month ago died following a violent one-car crash that ripped the car in which he was riding in two.

Adam Snyder, 19, of Grove City was the passenger in the car that crashed at 12:41 p.m. Monday.

He died at 12:55 p.m. Tuesday at St. Elizabeth's Medical Center in Youngstown, Ohio, according to Jesse Hoffman, investigator for the Mahoning County (Ohio) Coroner's office.

The driver, Tim Baker, 18, also of Grove City, was seriously injured when the car, a 1995 Buick Le Sabre, split in half after crashing into a tree along Irishtown Road near Cranberry Road in Pine Township.

Hoffman did not say what injuries caused Snyder's death.

State police at the Mercer barracks said the speeding car traveled over a knoll and became airborne for about 100 feet.

Snyder, who was not wearing a seat belt, was flown by medical helicopter to St. Elizabeth's Medical Center in Youngstown.

Baker was taken to the Grove City Medical Center before being flown to St. Elizabeth's. Authorities did not know if Baker was wearing a seat belt.

The road was closed for about three hours to allow police to conduct an accident reconstruction.

Rae Lin Howard, principal of Grove City High School, said Snyder graduated June 5.

"He was very well liked, had a great personality and was a really nice young man," Howard said. "He played on the soccer team and he was just a nice personable young kid who seemed to get along with everybody."

Howard said the school district was devastated after hearing about Snyder's death.

"It is very sad and tragic, and I just feel bad for his family and loved ones," Howard said. "I can't even imagine."

Dennis and Debby Snyder were his parents. He attended Portersville Christian School from kindergarten to 10th grade.

On Snyder's Facebook page, he said he liked to live life one way — with no regrets. His friends began leaving messages about how much they missed him Wednesday.

"Life is too short to regret anything you can't change," the Web site reads.

Snyder worked at Montgomery Truss in Grove City. Wayne Durniok, plant manager, said Snyder started working there a year and a half ago and had worked there full-time during the summer and part-time all year.

"Adam wasn't afraid of work," Durniok said. "For a kid his age, with his maturity level and his work ethic, he took a lot of pride in what he did."

Durniok said he always was willing to work extra hours and come in on the weekends.

"He worked in the saw room and he did a real nice job for us," Durniok said. "He was a special person. I miss him. I looked at him like a son. He helped my own son go through a rough patch, and he just was a good kid."

Durniok said the company is in shock. Many of the employees told him they can't stop thinking about Snyder.

"He always had a good attitude," he said. "I wish I had 20 more of him."

Durniok said he was thinking of Snyder's parents, who did a great job instilling a work ethic, sensitivity and good manners in their son.

State police said Baker has not been charged in the crash and that a decision on charges will be made in the next few weeks.

Arrangements for Snyder's funeral will be announced by the Smith Funeral Home in Slippery Rock.
