The recent college graduates were visiting Neuschwanstein Castle in Bavaria when man allegedly shoved them down a steep slope

Two US women who had just earned computer-related college degrees had gone to southern Germany to celebrate when a fellow American whom they met while hiking shoved them both down a steep slope last week, killing one and seriously wounding the other, according to officials.

Eva Liu, 21, had received her bachelor’s degree in computer science from the University of Illinois Urbana-Champaign in May. Authorities say she was sexually assaulted and pushed to her death near Neuschwanstein Castle, a famous tourist destination in Bavaria. Her 22-year-old friend Kelsey Chang had also just graduated from the same school with a bachelor’s in computer engineering – reports say she was attacked, too, but survived.
