What happens to coyotito in Chapter 1 of the pearl?

coyotito dies, yet the reason how is unclear. Most people think it was a tracker, who shot the gun towards the cave to silence the 'baby coyote' whining in the cave. Yet no one reads in between the lines. When one of the trackers tries to get away from kino, he starts climbing up the cave, Kino shoots at him, misses, then kills the tracker. So Kino could have just as well killed his son. Your welcome.
