I think you’re correct on that. I think it’s also possible he could have switched up his MO with the new dumping ground to throw off police. The sets of victims found on the beach had two different sets of MO’s which I believe is due to him switching it up as he became more experienced at killing. The police have linked all the victims to one person so I’m not going to dispute that. Like I stated in another comment they had to have the evidence to link them all,to make that claim.

I don’t believe baby doe and her mother were killed for the same reasons as the other victims though, it’s far too different. The most plausible explanation to me is that they were somehow in the way and he needed to get them out of the picture. The police have also claimed baby doe was mixed race, and LISK has shown to be quite racist as evidenced from the phone call with Amanda where he called her sister a “half-breed.” It might possibly also have something to do with that, but it’s just speculation.

But yeah, I’m near certain there’s another dumping ground, it’s just a matter of if it will ever be found and will the police be able to link it back to LISK?
