zhan tingting's guess wasn't wrong. the two victims died from having their necks crushed. according to the simulation of the scene, the two victims should have been hung up from the spot after their necks were wrapped by vines. then, after their necks were crushed, they were thrown down by the vines, causing multiple comminuted fractures in their bodies.
in addition, the hand gestures of the two victims at the last moment were completely out of the murderer's bad taste.
normal people would never be able to kill someone with such soft and fragile vines, unless the other party was an ability user.
however, among the paranormals in bai town, only two or three of them had plant-type abilities. three of them had alibis after the case, and the remaining one was a kid in kindergarten. none of them could be the murderer.
in the end, green devil was the only murderer left.
