Sheridan eventually finds herself pregnant and unsure as to whether or not Antonio or Luis has fathered her child. When Beth hears of Sheridan's pregnancy, she drugs Luis and makes him believe that he's slept with her, later claiming that she's become pregnant as a result. Afraid that the baby will unite Sheridan and Luis, Beth kidnaps Sheridan and holds her captive in a pit in her basement until Sheridan gives birth to a son on September 9, 2003. Beth then dumps Sheridan in the harbor and fakes the baby's death so that she can pass the child off as her own. The ruse works, and Luis believes that the boy, whom Beth names Martin Lopez-Fitzgerald, is theirs.
