New to this thread. Heartbreaking case. I've spent the last few hours catching up on media stuff and the latest press conference. Sorry, I haven't read all the posts to date.
My impression is, LE are almost certain they know who the killer is but can't quite get him.....yet, but they are close. Something said by a local in an earlier news broadcast made me think of the statement that they believe the killer either lives in Delphi, once lived there or works there. My guess is he grew up there as a child, with family and friends and may have moved to a neighbouring town or county but visits family and friends? In fact, I think he was very familiar with the area and quite likely played there as a teen himself. It struck me when it was "asked" of the killer, "What will those closest to you think when they find out that you brutally murdered two little girls, two children. Only a coward would do such a thing."
Another thing that struck me was when it was stated that he was between 18 - 40, but could be older than he looks. I have a 36 year old son that could pass for 26 easily. So it's no stretch to think a 40 year old could pass for 30. I think this recent press conference was to put him on notice. I guarantee he is under 24 hr. surveillance. Someone who can kill two sweet, innocent girls is capable of doing it again and LE will do their best to prevent that. Whoever he is, he now KNOWS they KNOW. Hopefully, they get what they need soon to get him off the streets and give the residents of Delphi a measure of peace again and justice for Abby and Libby. JMT
