The murder of Alexandra Nicole "Ally" Zapp occurred in the women's room of a Burger King rest stop in Bridgewater, Massachusetts on July 18, 2002. Section 121 of the Adam Walsh Child Protection and Safety Act (P.L. 109-248) is named the "Megan Nicole Kanka and Alexandra Nicole Zapp Community Notification Program" after her and another victim. Massachusetts' Sexually Dangerous Persons Law is informally called the "Ally Zapp" Law.

Also key to the prosecution's case was a statement Leahy made to police, in which he confessed that he intentionally stabbed the young woman. After initially conceding that he had only stabbed Zapp twice in the arm, he admitted to stabbing her in the chest when he was confronted with autopsy results. Leahy's criminal history dates back to 1981, with a history of sexual offenses beginning in 1984. Some of his victims were as young as 13 years old. With a mountain of evidence facing his client, defense lawyer Frank Spillane did not make a case to get his client acquitted of all charges, but instead concentrated his efforts on proving Zapp's death was not an intentional act of murder. Spillane argued that his client's actions were in response to
