I once watched a documentary on ID in which a mother told the tragic story of her student daughter who was murdered in the United States. She was around 20 years old and everyone was in shock, including her circle of friends. She was buried and everyone was in mourning. Later it turned out that the (now) husband of her best friend, who was also a pallbearer at the funeral, was the perpetrator. He was white, had short blond hair, and wore glasses. His name was Chris or Eric.
Which case is this?
