Context paragraphs:
Edgecombe County serial killer: The Edgecombe County serial killer, also known as the Seven Bridges Killer, is an as yet unidentified serial killer in the surroundings of Edgecombe and Halifax counties in North Carolina, United States.  There are ten suspected victims, all African-American women, and the remains of eight have been recovered.  It is suspected that Antwan Maurice, a registered sex offender who was charged with a murder fitting a similar profile, was responsible for the Edgecombe deaths.  All of the victims had a history of drugs and/or prostitution.

Sex offender: A sex offender (sexual offender, sex abuser, or sexual abuser) is a person who has committed a sex crime.  What constitutes a sex crime differs by culture and legal jurisdiction.  Most jurisdictions compile their laws into sections, such as traffic, assault, and sexual.  The majority of convicted sex offenders have convictions for crimes of a sexual nature; however, some sex offenders have simply violated a law contained in a sexual category.  Some of the crimes which usually result in a mandatory sex-offender classification are: a second prostitution conviction, sending or receiving obscene content in the form of SMS text messages (sexting), and relationship between young adults and teenagers resulting in corruption of a minor (if the age between them is greater than 1,060 days).  If any sexual contact was made by the adult to the minor, then child molestation has occurred.  Other serious offenses are sexual assault, statutory rape, bestiality, child sexual abuse, female genital mutilation, incest, rape, and sexual imposition.  However, particularly sex offender registration laws in the United States, may also classify less serious offenses as sexual offenses requiring sex offender registration.  In some states public urination, having sex on a beach, or unlawful imprisonment of a minor also constitute sexual offenses requiring registration.

Julia Tuttle Causeway sex offender colony: The Julia Tuttle Causeway sex offender colony (also called "Bookville" by former residents) was an encampment of banished, registered sex offenders who were living beneath the Julia Tuttle Causeway—a highway in Miami, Florida, USA—from 2006 to April 2010.  The colony was created by a lobbyist named Ron Book, who wrote ordinances in several different Miami-Dade County cities to restrict convicted sex offenders from living within 2500 ft of schools, parks, bus stops, or homeless shelters.  Since Book was also head of the Miami Homeless Trust, he was also in charge of finding housing for the released sexual offenders.  Under these ordinances, the only areas where sex offenders could legally reside within Miami-Dade County were the Miami Airport and the Florida Everglades.  Miami-Dade laws are significantly stricter than State of Florida laws on residency restrictions for sex offenders.  Florida State Law required that no sex offender could live within 2,000 ft from "where children gather".  Under that requirement, housing was possible; however, because of Book's lobbying, the Dade County Commission increased that number to 2,500 ft, thereby banishing hundreds of local citizens who then began gathering under the Julia Tuttle Causeway.

Megan's Law: 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.  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".

Sex offender registry: A sex offender registry is a system in various countries designed to allow government authorities to keep track of and activities of sex offenders including those who have completed their criminal sentences.  In some jurisdictions, where sex offender registration gan, registration is accompanied by residential address notification requirements.  In many jurisdictions, registered sex offenders are subject to additional restrictions, including on housing.  Those on parole or probation may be subject to restrictions that do not apply to other parolees or probationers.  Sometimes, these include (or have been proposed to include) restrictions on being in the presence of underage persons (under the age of majority), living in proximity to a school or day care center, owning toys or items targeted towards children, or using the Internet.  Sex offender registries exist in many English-speaking countries, including Australia, Canada, New Zealand, the United States, Trinidad and Tobago, Jamaica, South Africa, the United Kingdom, and the Republic of Ireland.  Sex offender registration does not exist outside of the English-speaking world, however.  The United States is the only country with a registry that is publicly accessible; all other countries in the English-speaking world have sex offender registries only accessible by law enforcement.
