Possibly, but MH being on the warrant, when he wasn’t involved in that December arrest, is a very crucial piece of information. Plus, MQ having those weapons wouldn’t necessarily mean he was involved in manufacturing(would look suspicious for sure) so I’m assuming SOMEONE had to have given LE some information that made it worth their time to further investigate.
If I’m the families, I’m hiring multiple PIs to track down these leads to other states regarding sex trafficking. These people are very good at keeping these girls hidden and cut off from the outside world.
