First time poster. Hello to all. Came to this site years ago after seeing a special on this case like most people (but never posted, strictly a bystander).
Nothing to add of any substance, but what a sad case simply because it will most likely never be solved.
There are to many directions this case can go in for a truly thorough investigation.
If this had been today a camera somewhere would have given a lead of some sort.
You could literally have 50 scenarios.
The mother being involved with someone nobody knew (same for her daughter).
The girls getting followed unknowingly, the folks she was set to tell on in court. A random nutjob, or a pair of nutjobs.
Also, we (average follower of the case) don't really have a clue what the law knows and is withholding. For obvious reasons of course.
Broken bulb in front could be something or nothing. The shade which I've read was stuck open(ish) I've had personally in my room growing up. I'd look out awaiting friends all the time and after many times the metal would kind of stay crimped open looking like I had just done it even if I hadn't touched the window all day.
The dog thing is a tough one because even though that breed is a yapper, I've had many dogs over the years and my current one would be classified as a yapper as well, she'd cower in a corner and be quiet if the person didn't react to her barking. I have it happen daily when I have unexpected or company unknown to my dog. She'll bark, but if that person doesn't react, she shuts down and hides.
The girls could have walked into something along with the possibility they flat out forgot to lock the door and someone walked in.
I'm born and raised in New York city and have 'door locking' engrained into my brain, but I can't lie and say I've NEVER forgotten my door open because I have. As you guys know, it only takes one time for something bad to happen.
Or it could be a rare one in a million type thing. I once had a guy bang on my door looking for someone at 4am (wrong apt or psycho, who knows?), but I didn't open the door. Who knows what would have happened if I had accidentally left the door open.
Also, it's very hard to guess what people will do in any given situation. I've agreed and disagreed with many theories I've read here. I can't even imagine how I'd react if someone walked into my house waving a gun if I'm dead asleep. Also, I've read folks mention the mom probably spoke to the kids when they got home, but that's another tricky one. I was always the type to avoid my parents when coming in late and odds are honestly, my parents wouldn't bother waking up so it's so tough to come up with a definitive conclusion.
She could have been bound up for all we know held up in that room with the dog and the perp(s) simply waited it out until they heard the girls finally simmer down and didn't hear any noise, then part 2 of the crime took place (the girls). That's with the assumption mom was the intended or just the available target.
Very hard to touch on all the things on this case because as I wrote in the beginning, way to many directions this can go in.
Could have been someone random just being a nutjob, someone specifically looking for the mom, looking for only the daughter, someone from one of the parties etc.
So hard because it was totally random, or totally planned in this case. That leaves so many options. Some details we read into even though they could mean nothing.
I didn't even touch on the kids cleaning up or anything else and I could go on for days in regards to possibilities.
Apologies for the length of the post
