Megan's Law is a US federal law, and informal name for subsequent state laws. How did these laws get their name?

Megan's Law is the name for a federal law, and informal name for subsequent state laws, in the United States requiring law enforcement authorities to make information available to the public regarding registered sex offenders. Laws were created in response to the murder of Megan Kanka in Hamilton Township, Mercer County, New Jersey by Jesse Timmendequas, a sex offender with two previous convictions of sex crimes against small children living across the street from Megan. Federal Megan's Law was enacted as a subsection of the Jacob Wetterling Crimes Against Children and Sexually Violent Offender Registration Act of 1994, which merely required sex offenders to register with local law enforcement. Since only few states required registration prior to Megan's death, the state level legislation to bring states in compliance —with both the registration requirement of Jacob Wetterling Act and community notification required by federal Megan's Law— were crafted simultaneously and are often referred as "Megan's Laws" of individual states. Thus, federal Megan's Law refers to community notification (making registry information public), whereas state level "Megan's Law" may refer to both sex offender registration and community notification.
