Major Story Arcs
Donna Gugina worked as an attorney in Gotham City, focussing on victims of child molestation. She had built up quite the reputation in her field, causing some to label her a crusader. In All Star Batman & Robin #8 she had a one-night stand with a man who revealed himself to be the Joker, and it was hinted that he had drugged her at an earlier moment.
She eventually confronted the Joker, asking him how he knew so much about her. He then attacked her and choked her to death with his necktie. He revealed he had picked her as a victim because ‘many good people’ would miss her.
The Joker later ordered Bruno to dispose of Donna’s corpse.
