Makayla's case is starting to become very similar to Heather Elvis. I would not be surprised at all if there's at least one other person involved.
Something else I thought of. I'm positive that the suspect's mom is not directly involved in Makayla's death at all. IMO, this case is harder due to the fact that his mom is a judge. I can't ever imagine having to prosecute a judge's son for murder, even if it is the next county over.
These are very small towns where everyone knows and is likely in some way connected to everyone else in town. Thankfully he was arrested quickly and I hope the prosecution has a very strong case against him.
