It's possible. It will be interesting to see what turns up in the trials. LE has collected evidence from cell phones, email accounts, etc. I doubt they would have told people they were going to kill the Rhodens and HG, they would have needed some other excuse to warn people away.
There were so many stories going around after the murders that seemed to point fingers at other family members of the victims. Lots of endless rumors on social media about James Manley discovering his sister's body, spreading fake suspicion about his sister BJM discovering the other bodies. JMO, that was all false information spread by the Wagners.
Remember Len Manley talking about how police came and woke them up in the middle of the night after the murders and took them down for questioning? They asked BJM "how much money did you get to kill your family?" JMO, all of the fake tips related to that came from the "local royalty" the Wagners.
