I didnt follow the case either but since coming on here a lot of people have talked about the similarities. There are a few things that make it hard for me to connect both crimes to one perp, the number one is that odds of him finding Abby and Libby on the 13th (appears to have some significance) and they just happen to resemble Lyric and Lizzie, we are talking some crazy odds of that just happening by chance. A lot of people have stated they do not see a SM connection and I would tend to agree with that, so if the meeting is truly by chance than how could it be the same killer....
I posted yesterday the fbi analysis for lyric and lizzies killer. I see that they are working on one for this killer. could be interesting indeed. moo
