Quigley, 30, died when the bus, carrying the women's lacrosse team to a match in Millersville ran off the road early Saturday. She was taken by helicopter to Penn State Hershey Medical Center where she died, Carlisle police said.
Three of the 23 players aboard the bus were hospitalized, the Pittsburgh Tribune-Review said.
Bus driver Anthony Guaetta, 61, was also killed in the crash. Quigley was pregnant, and her fetus did not survive, the Pittsburgh Post-Gazette reported Monday.
The campus mass Sunday evening filled St. Joseph Chapel, its lobby and staircase. Greensburg Catholic Bishop Lawrence Brandt extended his sympathy to the Seton Hill community, as did school chaplain the Rev. Jeremiah O'Shea, who asked that "the souls of Kristina Quigley, her unborn child ... rest in the arms of the Lord."
Members of the lacrosse team, dressed in uniform, sat in the front row of the church, the Post-Gazette said.
