A U.S. Peace Corps volunteer was found dead near a hiking trail in the Philippines last week, her head beaten in and her arms injured. Julia Campbell, 40, was hiking alone in Ifugao province, an area known for its beautiful views. Police found the weapon, a bloodstained bat, and arrested the husband of a woman who sold Campbell a Coke just before she set off. Police said they were investigating whether to charge the man with robbery with homicide or rape with homicide. Campbell, a freelance journalist from Fairfax, Va., taught English at a Philippine college.
