Constance Welch

Constance Welch also known as "the woman in white" was a young mother who temporarily went insane after she discovered that her husband had been unfaithful to her, she drowned their two children in the bathtub but claimed that it was an accident. She comitted suicide by jumping off the bridge near her home. Ever since then, she has gone around killing unfaithful men after convincing them to take her home but then saying she can never go home. She is, in reality, afraid of entering the home because she couldn't face her children. Sam Winchester almost falls victim to her when she tries to seduce him, only to be pushed away. She attacks him angrily. "I've never been unfaithful," he screams. "You will be," she responds, suggesting that she went after any man she wanted to, not just the unfaithful ones. When she is finally forced to enter the home, her children are waiting and kill her spirit.
