Emergency personnel work at the scene of the fatal bus crash Saturday on the Pennsylvania Turnpike near Carlisle in which the Seton Hill lacrosse coach, her unborn child and the bus driver were killed.

GREENSBURG — A small Catholic college outside Pittsburgh mourned the loss of a women's lacrosse coach who died along with her unborn child when the team's bus crashed on the way to a game, remembering her Sunday as warm, outgoing and a natural leader.

Students and staff packed into Seton Hill University's century-old Saint Joseph's Chapel for a memorial service for lacrosse coach Kristina Quigley and other victims of the crash. The program for the service read: “In Loving Memory of Kristina Quigley and Son.”

Earlier Sunday, team members and fans at a Seton Hill baseball game observed a moment of silence for the crash victims. With the players in the background on a cold day, students and other mourners visited a tribute set up in front of a lacrosse net next to the baseball field that featured bouquets of flowers, stuffed animals, a lacrosse stick, a whistle and a candle sat in front of a team photo and signs reading “In memoriam — Kristina Quigley — Forever a Griffin.”

Players and coaches from Seton Hill were among 23 people aboard when the bus crashed into a tree Saturday morning on the Pennsylvania Turnpike outside Harrisburg. The team was headed to an afternoon game at Millersville University, about 50 miles from the crash site in central Pennsylvania. Police are investigating the cause.

Quigley, 30, of Greensburg, died of her injuries at a hospital, Cumberland County authorities said. Quigley was about six months pregnant, and her unborn son didn't survive. The bus driver, Anthony Guaetta, 61, of Johnstown, died at the scene.
