Does thresh die in the hunger games by cato or mutts?

Thresh doesn't die in the Hunger Games by either Cato or the mutts. He is killed by Clove, another tribute, in a desperate attempt to protect Rue, the girl tribute from District 11.

Here's the breakdown:

* Cato is ultimately the one who kills Rue, not Thresh.

* The mutts are not involved in Thresh's death. They are introduced later in the Games, after he is killed.

It's a pivotal moment in the story. Thresh's act of vengeance against Clove and his fierce protection of Rue is a powerful display of loyalty and compassion, even in the brutal context of the Hunger Games.
