That doesn't explain why if he wanted more attention he would dump the G4 along OP where none of the other 6 victims had been found since 1996. If he wanted attention for the G4 wouldn't he dump them somewhere he know they would be found quickly so as to get the attention you claim he craved?
And if the mo changed because he brought someone else in....why and how would he bring a police officer in as his partner serial killer?
If your poi worked out on a ship out of New Bedford during the time frame of the New Bedford killings, does that actually mean he was there at the time? Or does it mean he was away from New Bedford working on the boat?
According to this:
"Between 1988 and 1989, ERNESTINA visited ports up and down the eastern seaboard and northeast into Nova Scotia and Newfoundland, returning to her former homeports while educating a new generation of seafarers"
