As Lori Vallow and Chad Daybell await their upcoming trials pertaining to the disappearance and subsequent discovery of Vallow's Tylee Ryan and Joshua "JJ" Vallow, on Daybell's Idaho property, new concern has emerged about effectively utilizing any evidence that emerges throughout the ongoing investigation.

On Tuesday's episode of "Crime Stories with Nancy Grace," Nate Eaton of East Idaho News discussed the current state of Vallow case and the possibility of new charges that they could face down the road.

In the new installment, Grace explained that prosecutors in Madison County were "compelled" to drop Vallow's felony desertion charges due to the fact that her children seemingly died in September, which would indicate that she did not actually desert them. While she still faces charges of conspiracy to destroy, alter, or conceal evidence, Eaton indicated that additional charges may come after forensic testing is completed.

According to Crime Online, Eaton revealed that a source with inside knowledge of the investigation was able to confirm that law enforcement officials are attempting to hold the couple accountable for any crimes they may have committed, but at this time it appears as though Alex Cox, Vallow's deceased brother, played a large role in the events that followed Tylee and JJ's disappearance.

“We’ve got one shot at this. We can’t mess it up,” Eaton stated, appearing to paraphrase the conversation that had taken place with the insider.

However, Daybell and Vallow could also face "more serious charges" if the autopsies, including pending toxicology reports, reveal new details about what took place. As for the status of the remains, a June 24 press release from the Ada County Coroner's Office indicated they had been transferred from the Freemont County Coroner's Office to Ada County for additional testing, but it's unclear when the results would be available.

As for what's ahead for Vallow, a recent ruling by Magistrate Judge Farren Eddins indicated that her 2020 court dates would face new rules and restrictions. Additionally, Mark Means, Vallow's attorney, also recently filed a motion that made a specific request leading up to her upcoming trial.
