She was a young woman who became the The Trinity Killer's first shown victim.
Lisa was ambushed in her bathroom by Arthur Mitchell. Both are then seen lying naked in the bathtub while she struggled. Arthur wrapped his legs around her and held her in a rear chokehold until she passed out, stating, "It's already over." He then cut her femoral artery, which roused her and she again tried to free herself. Arthur held up a mirror so he could watch her facial expressions as she slowly bleed to death.
- Arthur is later showed 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.
