I really hope the young couple who clearly doted on their baby are not mixed up in drugs..but then again they also killed the mother's little brother.. surely he can't have been!? Collateral?
Possibly could be a case of wrong place/wrong time and old enough to be an eyewitness.
But 15 is definitely old enough to be mixed up in the drug life.
Sadly, there are many kids even younger than that who are couriers and dealers.
I'm not saying that's the case with this poor teenage victim here, it's just given the set of circumstances, this case has the whiff of drugs in it somewhere to me...I think it's a virtual certainty that the perpetrator(s) will have a history of drug-related offenses.
The only other possibility I see is an armed carjacking, but I haven't seen whether or not LE has verified whether that minivan/SUV vehicle of interest matches the description of a victim's vehicle or not.
There's been zero reporting of an escaped convict, so it appears highly unlikely that a prison being in the area would be at all related to this case.
One big dissimilarity between this case and the Rhoden family murders out of Ohio is that in this case, apparently the baby girl's bio dad is one of the victims. In the Rhoden case, the bio dad was one of the perps, and custodial issues were a primary motive for those murders. That doesn't fit with this case based on what we've been told so far.
If we find out something different about paternity or victims' familial relationships to the baby, then that would be noteworthy.
