Did Judas die from hanging or from falling?

It's rather easy to reconcile these, here are a couple of possibilities:

First, Judas tried to kill himself by hanging himself. And this is not always a successful way. Maybe he tried, and failed (as have many others who have tried to commit suicide by hanging). Then after some time, he threw himself off a cliff and fell upon some jagged rocks. Keep in mind that it is not uncommon for people who commit sucide to have tried it before.
Judas could have tied a rope to a tree branch that extended over a cliff (after all, you have to get some space between your feet and the ground to hang yourself). In this situation, the rope/branch could have broke before or after death, and Judas plummeted to the ground and landed on some jagged rocks.
