She might have been lured into a trap by a dark wizard who was after the Potter family. The dark wizard could have used her as a bait to get to James or his parents.

This would add a sense of helplessness to the situation as everyone around her tried their best but still couldn't save her. It could also be that she got lost in a dangerous magical place like the Forbidden Forest and couldn't find her way out, ultimately meeting her end there.
