Let me suggest what may have occurred. Suzie was lured out of the home first by someone who had met her at the party on Hanover. She went willingly having recognized the car when she cracked the blinds. She seemed to have had a propensity to be taken in by bad actors. In any event, once she got outside, a commotion ensued awakening Sherrill who went to investigate. That is two out of the house. Stacy does not appear to have gone voluntarily.
What follows is speculation:
Whoever did this must have (as having been suggested) used a gun to gain compliance. And a hat, according to a source I regard highly. In fact, this source had a connection to LE who revealed the name of the perp. I had a long, long running communication with this source and we went over the case point by point, many times on many occasions.
What differentiates him from the others is that he wasn’t into playing games and intimating things he didn’t know. What he did tell me was verified by facts I could check with known sources.
What he told me one time was that he and a trusted friend went to the suspect’s place of employment and viewed him on the job. I have NO doubt as to his veracity and sincerity.
None of this proves anything. I do, however, believe the police know who committed the crime. But the evidence is not there to convict the perp.
What has been so frustrating is that so many people have attached themselves to this case and then disappeared into the woodwork. I have no doubt that the perp has followed this case and has posted here under numerous screen names. Although that is against the terms of service here, their identity and location can be disguised with a VPN.
