I know before u go nuts saying "wait she didnt die here!" well the movie is different from the book in some ways and the fact that the district 4 female tribute was allies w/ the careers never happened.
Katniss locked her eyes at her when she ran and picked up a backpack. She fled and went into the forest in safety. A few minutes after the bloodbath in the forest, Katniss hears her scream in the forest indicating her death from the hands of the careers.
Cato hit the District 4 female in the stomach with his baton, injuring her, and threw her into a supply crate, causing her to somersault. As in the pic.
