In Aliens vs. Predator: Requiem (terrible, terrible movie):
One police officer discovers the Predator in the woods whilst continuing the search for a missing father and son. The Predator kills him, and he is later found hanging from a tree, skinned.
Aside from the apparent desire of the screenwriter to include a copy (sorry, homage. No, wait, it is just copying) of every memorable scene from both franchises, why did this happen?
The Predator didn’t hunt this character. It killed him while he was running away, presumably in an attempt to avoid attracting attention. Why skin him?
