idaho murders

another murder case that happened Sunday. 4 Idaho College kids were stabbed to death wtf. how awful and senseless this is... and right by Thanksgiving too. I feel so bad for the families. apparently there were 2 other room mates in the house where the other 4 were killed. the 2 room mates weren't harmed at all. that's weird, like how does someone kill 4 people in a house and you not hear anything??? they said there wasn't a break in either and that this was a targeted situation. Twitch recording shows 2 of the girls ordering food from a food truck late at night around other college kids and this one guy people are talking about also visible in the twitch stream. 

I watched the twitch stream recording a couple of times and yea it definitely seems odd. so the stream shows the 2 girls walking in frame at the same time as this brown jacket/hoodie guy and the guy is seen standing far back from them while the girls go up and order their food. then they move over the other side of the food truck window to wait on their order and the brown jacket/hoodie guy walks over close to them. then he starts talking to this other  big guy... from my perspective it seems the girls do not know the man at all. they never talk to him. but the guy points toward them and the big guy started talking and pointing a bit and they keep chatting. at one point one of the girls seems to kinda talk to the big guy but not the brown jacket/hoodie guy... then the girls get their food, walk off and the big guy points at the girls in a "hey they're leaving..." way and the brown jacket/hoodie guy makes a gesture like "wtf?" and then follows after them. he puts his hand up like he says something and takes off in the other direction. super weird considering they don't acknowledge him at all and then he takes off when they do, after following them over to the food truck 2nd window. what  the  fuck.

obviously this guy could be innocent but that was weird. then the 2 room mates that were unharmed is weird too considering they were in the house when these other FOUR were stabbed. 4? how do you kill 4 people? and not alerting anyone in the house. idk it's weird as fuck and I hope they can solve this fast. I pray for the families cuz fuck. I couldn't imagine they're away at college and they get a phone call their children were murdered. fucked up. why are people like this? :(
