WEST BUFFALO TOWNSHIP -- A man could spend up to three months behind bars for his role in a crash in Union County that killed an 18-year-old girl.
Christopher Libby pleaded no contest Friday to involuntary manslaughter charges.
It's now up to a judge to decide whether he will accept that plea agreement. That ruling is expected by March 15.
The crash happened in August, 2011 along Sportsman Club Road in West Buffalo Township, near Mifflinburg.
Authorities said the car driven by Libby went off the road, rolled multiple times, and came to rest in the woods.
Both Libby and his passenger, Emily Kunkel, 18, were thrown from the vehicle.
Kunkel died at the scene.
Her family was in court Friday.
"It's just sickening to see him sitting in that courtroom. He won't even say if he did it or not," said Brian Gearhart, Emily's family member.
Emily Kunkel's aunt's and cousins wore t-shirts with her name on them and buttons with her pictures.
"It's just hard, but we're here for Em. We try to support her as much as we can," said Eva Bendas, Emily's cousin.
Emily's family says LIbby was known to speed on the back roads near Mifflinbug. Troopers say Libby had a nitrous fuel system in his car. That provides a burst of speed, but it's not known if it was used at the time of the crash.
Family members of Emily's also say they're upset Libby only faces a maximum of three months in jail.
"She was innocent, and she didn't deserve this. She was a beautiful girl, and we all loved her," said Gearhart.
