If the police department was to arrest Brook Houck on suspicion of murder, it would also make it a lot easier for the grandparents to gain custody, or at least partial custody.
Brook Houck is still walking around a free man, Nick Houck has been fired for impeding an investigation.....now what ?
I'd be interested to know if the Rogers family feels like progress is being made, or if this is simply the law enforcement equivalent of putting a band-aid on a gunshot wound. I'm sure Brook Houck will keep his brother employed through his contracting business, if he hasn't already been doing it since Nick's suspension. This is going to allow the two brothers to bond together even tighter now that those pesky police investigators have been removed from the equation.
The county sheriffs comments yesterday regarding his suspicion that the brothers are connected to her disappearance was interesting, but all that's going to result in is the two of them lawyering up and refusing to talk any further. Hopefully LE has a trail of breadcrumbs that provides enough evidence to form a picture of what happened to Crystal during that weekend. It's going to have to be strong enough to convince a grand jury as well as a seated jury if this case ever goes to trial.
Murders in this community appear to go largely unsolved, for reasons that aren't very clear.
