Who won the Hunger Games in the 2nd Quarter Quell?

The victor was Haymitch Abernathy.

Haymitch Abernathy was the victor of the 2nd Quarter Quell. He used a force field as a weapon against the Capitol and in return for punishment, President Snow killed his family. Haymitch used the force field to kill the female tribute from District 1. She threw her ax and was trying to staunch the flow of the blood from her empty eye socket, in which Haymitch somehow plucked it out. She threw her ax and it fell into the force field. Then it came back up and buried itself in her head. The trumpets blow, they remove the girl from District 1's body and announce Haymitch's victory.
