One snake two kid in same bed TOGETHER. Yep could be what happened. Posters are assuming kids were awake and apart in the room.
See #63. It appears the snake was in the apartment.
But, there’s an autopsy. I can’t think of why 2 friends visiting a kid would be the target of some evil scheme to off them in their sleep, but it’s not an impossible scenario.
On the other hand, there is a snake, it does constrict, they do appear to have been killed in a manner consistent with a snake, the snake was captured in the apartment, the police don’t seem to be expressing any doubt, and it was on the prowl in an unknown environment.
