She was a young woman who became the first shown victim of The Trinity Killer.
Lisa is ambushed in her bathroom by Arthur Mitchell. Both are then seen lying naked in the bathtub while she struggles. Arthur wraps his legs around her and holds her in a rear chokehold until she passes out, stating, "It's already over." He then cuts her femoral artery, which wakes her and she again tries to free herself. Arthur holds up a mirror so he can watch her facial expressions as she bleeds to death.
- Arthur is later shown in another episode climbing into a bathtub with his current wife and holding her in the same way, although more gently. He does not kill her.
- According to Debra Morgan, Lisa had recently been promoted to Sous-chef.
