Sunday school teacher Melissa Huckaby, a neighbor of the Cantu family, was arrested on suspicion of the kidnapping and murder of Sandra Cantu yesterday. The family had been under investigation during the past week, and Huckaby revealed enough information during questioning on Saturday that police had probable cause to book her. Huckaby had said earlier in the week that Cantu had stopped by her house to play with Huckaby's daughter but was turned away by Huckaby because her daughter still needed to "pick up her toys." Huckaby had reported that her suitcase had gone missing the same day Cantu disappeared and that she had later found a note with the words "suitcase" and "water." Surveillance footage showed Cantu turning toward Huckaby's house before her disappearance. According to the FBI, it's unusual for a woman to be involved in such a case.
