Question: My Friend Dahmer is a film about an American serial killer and sex offender who committed the rape, murder, and dismemberment of seventeen men and boys, and was known as what?
Context: Jeffrey Lionel Dahmer (May 21, 1960 – November 28, 1994), also known as the Milwaukee Cannibal, was an American serial killer and sex offender, who committed the rape, murder, and dismemberment of seventeen men and boys between 1978 and 1991.  Many of his later murders involved necrophilia, cannibalism, and the permanent preservation of body parts—typically all or part of the skeletal structure. William George Bonin (January 8, 1947 – February 23, 1996) was an American serial killer and twice-paroled sex offender, also known as the Freeway Killer, who committed the rape, torture and murder of a minimum of 21 boys and young men in a series of killings in 1979 and 1980 in southern California.  Bonin is also suspected of committing a further fifteen murders. 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.

Meirhofer (June 8, 1949 – September 29, 1974) was an American serial killer who committed four murders in rural Montana between 1967 and 1974 — three of them children.  At the time, the Federal Bureau of Investigation was developing a new method of tracking killers called offender profiling, and Meirhofer was the first serial killer to be investigated using the technique.  Offender profiling is a method used to learn clues about the characteristics of an unknown killer from evidence at the scene of the crime and establish their behavioural patterns before they reach the height of their criminality. 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. God's Spy is a 2007 bestselling thriller novel by Juan Gómez-Jurado originally published in Spain.
