It did not take long for John Heegard to put the clues together. Valencia McMurray was one of the most promising students in his Advanced Placement U.S.History class at North High School in Minneapolis. But the junior was missing three, four, five days in a row, often just showing up to pass an exam—no small feat, considering the legendary toughness of Heegard’s tests.
Heegard tried but was unable to reach Valencia or her family to check if she was okay. When she did show, he noted her usual wit and intellect were often muted by depression. “It was evident something was up,” Heegard says. “When a kid’s that bright, it doesn’t take long to figure out they’re having some kind of trouble.”
