Like I said on earlier on, I had a feeling that MacKenzie was just the tip of the iceberg. From following other cases, this type of crime doesn't happen out of nowhere. There's a progression.
I still think MacKenzie's murder was his first. The sexual abuse, child




, kidnapping etc. tells me that there is more out there that we have yet to hear. He's been all over the map. His victim is not exclusive to one type.
I think we're going to hear that his victims where terrified of him which is why they didn't report the crimes to LE. I also think that he managed to manipulate them into coming to his home and the fear of appearing to have put themselves into harm's way is keeping others from reporting. BTW, I get it.
He was a serial killer in the making. Thankfully he is off the streets.
