Snipped.
I believed the witnesses saw him in the hallway though that's a good point - if it was in his room they could tell more about whether was open or not if they noticed that.
I believe it's been speculated that someone, either the killer or a LE agent with imperfect knowledge of Jewish customs may have opened the window as part of an attempt at death rites, or that the killer opened it to throw out something he'd forgotten or just to throw off anyone who found the crime scene.
I wonder if there were blinds in his room however, even if the light was on all night, it could have been harder to tell he was alone if they were down. Also if the light was on, the murderer must have switched it off afterwards OR whoever found the body. In the latter case I think it would have been mentioned but there's already so much lack of available info on this case, maybe someone mentioned it being on in the morning.
That's a good theory... maybe just the students being outside, etc. and discussing it. As I've said before I think that someone overhearing or being innocently told the general info that Chaim had his own room on the third floor could have done it, they wouldn't have all the details on the dorm or not know them by heart, but would know that Chaim was one of the two only students who had their own rooms.
As to the broken lock, in the other thread someone said the staff didn't know about the lock. Assuming it's true, for the kids to wonder then they knew but didn't know the staff didn't know - which sounds odd, I think they would have told the staff since it seems the sort of environment where kids wouldn't be inclined to lie about it or hide it from them at all, especially with Halloween coming up and worrying them to the point of wondering where the designated cop was.
I think nobody knew about the lock if the staff didn't know. I think that the staff being unaware makes sense - I doubt they would have allowed the lock to remain broken, especially on a night they anticipated could be a problem. Which is why I wonder about what exactly was wrong with the lock and if the killer could have been the one to break it.
Good point about the temple.
As to the kids walking to the temple, I don't know but I assume the school would have its own, kind of how like Catholic boarding schools often have their own church in the premises. It seems like if it was allowed, then it would have a temple on campus, as it would have been easier - going anywhere with a group of teenagers and trying to get them to walk quickly and not get distracted or lag behind sounds tough.
I also think everyone in the community was aware of the school already, seeing the kids walk to a nearby temple would have only added to it, but not strictly necessary for an anti-semitic murder.
The murder weapon wasn't found so I think the media as well as LE can only make educated guesses based on the type of wounds.
The rest of your comment makes sense and I don't have anything to add to it so snipped it. However, the thread linked on pg. 1 is very helpful and two people chime in about Yeshiva life. One of them is unrelated to this case and the other one says he was a classmate of Chaim's. According to both of them, life in a school of this type would be quite sheltered. Going from the info on there I don't think the kids would have been allowed out of campus on their own. I know this is true in a lot of other boarding schools, some let kids (depending on their age, usually) go out after class if they respect a curfew while others don't let kids out of campus without a specific special request. I doubt they would have been taken off-campus for fun, I can more easily see in-school events like get-togethers and playing games in a common room, like a family's evening in. :twocents: If they met the murderer off-campus I think a field trip would be more likely.
However I don't think a supervising teacher would let the kids speak to strangers outside of campus.

Someone talked about eggs being thrown at students, that sounds really bad... I wonder, what was the police's reaction to it? Why didn't a cop guard the building that night - even if it wasn't directly connected to the murder, the individual cop could be anti-semitic OR it could show that the non-Jewish community in the area didn't care much about keeping these kids safe.
If it was within the local town, I think someone knows more than they're saying. I find it hard to believe that an anti-semitic murderer among other anti-semitic people wouldn't brag.
All my :twocents:, :moo:, and if I posts were snipped just for space reasons.
