In 1999, 12-year-old Cally Jo Larson was found murdered in her own home and it changed the feeling of security residents had in the small town of Waseca, Minnesota. Despite a meticulous search of the Larson home and an exhaustive investigation, police had no suspects. Then a string of burglaries several months after the murder led police to the home of Lorenzo Sanchez, where they found a cache of stolen goods, which included CD cases similar to those belonging to Cally Jo. That evidence would make the case, and bring the killer to justice.
