It all had to do with her purchase of bullet proof vests. These vests were not even used in the murders so I don't know why they were such an issue, but at any rate she was accused of lying about when she bought them.
After many many months of the prosecution asking for receipts for the vests, she was finally able to produce them which proved they were purchased after the murders in May 2016.
She was able to prove she did not lie to the Grand Jury, she just couldn't remember where she had purchased the vests.
JMO, the state dropped it's charges with prejudice in part because they weren't ready to reveal all the evidence they had against FW and the events that happened at FWF. They were moving towards trials for the killer Wagners and weren't going to show their evidence or strategy. Not only that, even more evidence and witness testimony was discovered by LE after FW's case was put on hold
- For instance, there are witnesses who saw a BPV in Billy's room at FWF the week before the murders, along with a gun, ammo, etc.
- FW offered to help provide alibis to protect Billy and his family from being arrested for the Rhoden murders
- FW was overheard discussing threats or punishment against certain "witnesses" who helped the prosecution charge the Wagners
