Someone Knows Something

A decade after her disappearance, a previously uninvestigated local man comes forward at a family gathering and confesses to killing Christine Harron. Chrissy's mother Mary Ann is told that the case is a "slam dunk". And the outcome of an upcoming trial could mean she will finally learn the truth. But this is just the beginning.

Chrissy Harron didn’t feel well on May 18, 1993, and stayed home from school, but eventually her mother insisted that she get to afternoon class. Chrissy left, slamming the door, and would never be seen again. How can someone simply vanish, and did the local police find anything of use in their investigation?
