Christmas Mourning

It's coming up on Christmas and Deborah and Dwight's one-year anniversary, but the fatal car crash of a popular teenage cheerleader dampens everyone's holiday spirit, especially when it's discovered that she was murdered. When two other students are shot to death, everyone's talking about the killings, and familial connections (Deborah's mother-in-law is the high school principal, and one of her brothers is the assistant principal, not to mention the various nieces and nephews who are students) mean that Dwight and Deborah gain plenty of information just by visiting with relatives.
