Regarding cameras. There was a case in OK with the Bever brothers (yes, almost same last name as MB) They killed their parents and all but two of their siblings (one called 911 and that was the only reason the other two survived). But, I do remember reading that they had cameras set up throughout their house to record the murders. They planned to "publish" them later so they would be famous. I'm thinking the same thing with this perp. He/she knew the cameras were there, and that they couldn't be identified and relished the thought they would be recorded and we would all see it.
I thought for sure by now LE would be able to piece together who did this and get themThe longer it goes, the scarier it gets. This perp was so twisted in so many ways. I can see them sitting back reading comments and just smirking at what they think they are getting away with. I'm 50/50 on man or woman but I lean towards a woman. If a man, I'm really leaning towards younger (but not under 18) only because I have the thoughts of the Bever brothers case in my head. It's similar to this but they were teenagers and what they thought was the "perfect" murder didn't turn out to be.
And on a woman doing this, nothing like a woman scorned to make her research and detail out everything and want to make the person "pay". Would I know half of the things he/she did in the video, nope, wouldn't have a clue. But if someone has been around LE their entire life and has some knowledge, YouTube is an amazing thing and you can learn quite a bit. That's the only reason I'm NOT leaning towards teenager. I think they could have planned it but there would be some flaws because they are young and inexperienced. This person tells me some experience has been had.
Ugh. Come on LE, you can do this!! Or, if you truly are clueless, give us some more details to help.
The detail, research, time spent, knowledge of victim, fact he owns this weird outfit, and all of these tools, knows about surveillance cameras, and his brazen cockiness really makes me wonder if it isn't some serial killer who stalks people he meets either online or in real life. He obviously doesn't think he will ever get caught. I wonder if he yelled out POLICE when she first walked in. You need to come with me there's been a break in. Something like that maybe.
