Better explanation:

Tiffi, because:
 * 1) It couldn't be Dino since the victim was dragged in, and a dinosaur's killer instinct would allow him to eat him up instantly without needing to actually drag him elsewhere.
 * 2) There is proof that Tiffi could be the murderer compared to Enderman. Tiffi said that she saw someone push the victim in, but the tests proved that he was dragged in, not pushed, and differentiating between pushing and dragging (or pulling) is quite obvious. Thus this proves that Tiffi is lying.
