The zip ties and rope was discovered Jul 3, 7 days after he was arrested for aggravated kidnapping, murder, etc. The remains found in the fire pit clearly points to murder .
I think I answered my own question. I did some more searching and found this:
"Fraud” is only involved in aggravated kidnapping. It is defined as any type of deliberate or intentional misrepresentation (i.e. a trick) for the defendant’s own benefit. This type of conduct is common in rape and lewd acts with a minor cases, wherein defendant promises the victim to take her home, but in fact has no intention of going to the victim’s home."
