A man who answered the door of his family’s Pennsylvania home wearing a robe and holding two knives is accused of stabbing his sister and their elderly parents to death.
Kevin Castiglia, 55, allegedly hacked up his elderly parents, Fred, 90, and Judith, 84, as they slept and then stabbed his sister, 53-year-old Deborah Castiglia, to death when she discovered their bodies, Bucks County prosecutors said Wednesday.
