So, we have a Friday night Halloween and a Saturday morning November 1st (which, as I understand it, Chaim was discovered November 1st.. very early, still dark.. is this correct?)
We need a general idea what the heck Chaim's dorm might have looked like.. was there another way to get out of Chaim's room besides the brightly lit hallway? If so, then the murderer may have used that. If he was forced to go out via the hallway then we need to know about the hallway. Was the hallway floor tile or carpet, light or dark floor? If the floor was dark then the murderer might have been able to go down it and even if some blood dripped, it would not be as easy to notice. Once he got outside, someone might mistake his appearance for a Halloween costume. Especially since he does not seem to have been noticed near the dorm. Were there trees or bushes or anything else around the dorm that a murderer might use to conceal himself?
I feel like we would have heard about blood being found outside the room. Also, from what I understand they shut down that section of the dorm for a while after the murder. I'm sure they scoured every inch for any sort of drop of blood.
How the killer got out of there without spilling a drop of blood outside the dorm room is one of the mysteries of this case. My theory is that he stayed in the room long enough that the blood indirectly dried up, thus no longer dripping anywhere.
Also, the neighborhood.. were there many Jewish people (as in percentagewise)? Was it likely if someone came into the neighborhood and committed a murder that the victim would be Jewish?
If so, then this could explain a person who hated Jewish people. He would not need to know very much about any particular victim, he would be able to find a victim easily just by going to the neighborhood. I still say if it is such a person, then nothing in Chaim's room relates to a death ritual other than the candle that was placed by a rabbi after Chaim was discovered. Such a person would know very little about any particular Jewish belief or custom. And if he did know, would disregard it. (Moo)
I don't know if there is such thing as targeting a random house in an entire neighborhood to commit a hate crime. What if the person you kill isn't Jewish? Wouldn't the doubt sort of ruin it for someone looking for that emotional release?
If you look at the Google Map you'll notice that this isn't just a "random house in the neighborhood". It looks different and is taller than the other houses. I feel like that specific building was targeted. My opinion is that the student who was killed was random, and was targeted solely because he slept alone.
If another student, he did not necessarily have to be from that dorm. He could be from another dorm and just know the code to get into Chaim's dorm. it was said in the article that Chaim had a sharp tongue sometimes, maybe someone got overly upset over something he said. If there were students there getting molested, then some students would be really on edge from the stress from it. What if nothing was happening to Chaim and he knew nothing? It would be easy to make a remark that meant nothing particularly bad to him, but to a kid who was traumatized it might sound like Chaim was being cruel. (Not blaming Chaim here, but the evil child molester that some articles say was present at this school during this time period.) MOOO/speculation
This bring us back to how secure was Chaim's dorm? Was the code known by people who did not live in it? Students in other dorms? Alumni? Could a person watching have learned the code by watching students going into the dorm? (This would be stranger murderer lurking around somewhere if there was such a place he could lurk.)
Here's my thoughts on this. If one of those kids was a ticking time bomb and went ahead and committed this murder and got away with it, I'd imagine that kid grew into someone who has quite the arrest record. Do we have anyone like that?
Also, if this was someone from inside the dorm that did this: where did they put their bloody clothes? Take a knife and start stabbing a watermelon as hard as you can, let me know if anything at least gets on your sleeve.
Thus, I'll make the assumption that the dorms of the other students were searched and their clothes checked. Meaning the student would need to leave the building, probably walk a couple streets down to the boardwalk, dump the clothes, walk back to the dorm, then sneak back into the dorm room without waking up his roommate. Then deal with police interrogation, lie detectors, and suspicion from students and family for the next 25 years without raising alarm.
Using all those assumptions, I would make the statement that it is FAR easier to simply sneak in, commit the murder, and sneak out, than it would be for the murder to be committed by someone residing in the dorm.
