But for LE looping in DEA/SONIC, this would be my leader in the clubhouse. But--pure speculation--I don't see LE involving multiple drug enforcement/interdiction agencies absent LE having some solid lead that connects DS's disappearance to drug activity.
Would the smoking-related key-chain fob and DS liking paraphernalia related items on her etsy account be enough for LE to call in the drug squads? I don't know. Given the prevalence of smoking among DS's generation, it seems the drug guys would end up involved in most every disappearance; if having those items on her CV were enough.
But anything's possible, especially with the limited information we have.
