Winnie Tyler was Jacob Tyler's wife. He abandoned her in June 1983, even though he knew she was pregnant.
She gave birth to twins. Needing money, she decided to sell one of them to the Jerichos. Her daughter Bev secretly followed her and saw the transaction, which took place on Christmas Eve 1983. However, Winnie was so ashamed of what she had done that she never spent the money, staying in the Quadrant and raising Bev and the twin she kept, Gabriel.
In 1993, Eva Jericho brought the sickly Steven to Winnie, asking her to exchange the "damaged goods" for a healthy son. The proximity of his twin caused Gabriel to draw the remaining life from Steven, killing him. This vampiric event activated the N-Form that had been searching for what it thought was a vampire infestation on Earth. After finding them, it merged with Eva and Gabriel. It then activated the engrams in the cocaine it had been distributing, some of which Winnie had used, killing her and all the others who had used it. (TV: Damaged Goods)
