I really wonder how long she's been doing this, and why she was so angry this time that she killed her. And I REALLY can't wrap my brain around why Sandra would go back there if she had been abused before...unless she was drugged and didn't remember.
I don't think Sandra had been abused before, or else she'd wouldn't have been happily skipping to Melissa's house. In fact, I think the reason for Sandra's death is that Melissa tried to molest Sandra in some way, and Sandra fought back.
Melissa may have drugged Sandra and/or asked her to go with her to the church to do something. I think the folding bed that LE removed from the church is where the crime was committed. If drugs were used, perhaps they didn't completely knock Sandra out, and she began struggling when Melissa started molesting/raping her with an object. If drugs weren't used, it could be that Melissa told Sandra they were going to play a game that was their special secret, and when Melissa started molesting Sandra, Sandra decided she didn't want to play that game, and/or said she was going to tell someone what Melissa did, and it became a power struggle that ended in Sandra's rape and death.
Melissa Huckaby is obviously not a mentally or emotionally stable person. It could be she was sexually abused herself, and was doing what many sexual abuse victims do, re-enact the abuse on other victims, thus perpetuating the cycle. If that is the case, then there could be others whom Huckaby has molested/raped, and that is what LE is obviously thinking when they asked for members of the community to come forward if their child had contact with Huckaby.
It is also possible Huckaby might have been filming *advertiser censored* for herself or for others. Early in the investigation, I read that Huckaby's five-year-old daughter had been removed from the home by Child Protective Services. I hope that is the case. If Huckaby's own daughter hasn't been sexually molested, I will be greatly surprised.
I want to say something about the alleged "psychotropic" drugs that some people are saying is the cause of Huckaby's rape and murder of Sandra Cantu. What you read in the media is over-blown reaction to medications that do much more good than harm. Anti-depressants don't make normal people into rage-filled murderers. That scenario has been promoted by anxious defense lawyers whose clients have no other leg to stand on. There is a very small percentage of people who do have reactions to these kinds of medications, but they don't happen in a vacuum. There are other factors involved.
As more evidence comes to light in this case, I think we will find a pattern of abuse in Melissa Huckaby's life. Her failed marriage and relationships, poor job record, petty thefts, spending sprees and bankruptcy, are only the tip of the iceberg. These are just the things we KNOW about. There is much more we don't know.
It is also possible that Melissa Huckaby is bi-polar with extreme mood swings or has Disassociative Identity Disorder (formerly called Multiple Personality Disorder). It doesn't excuse what Huckaby did to Sandra Cantu, or negate the evil of how Sandra died, but it might explain how a seemingly "normal" young mom could rape and murder her daughter's playmate.
