SERIAL KILLERS AND MURDERERS
Over several decades, three serial killers have raped and murdered gay men in the UK: Dennis Nilsen (1978-1983), Colin Ireland (1993), and Stephen Port (2012- 2015). While David Copeland (1999) does not fit the criteria of a serial killer, he was responsible for the 1999 London nail bombings which included the Admiral Duncan pub in Soho, London where three people were killed and a total of seventy-nine were injured, many of them seriously.
Outside the UK, Canada recently sentenced Bruce McArthur accused of killing and dismembering eight men between 2010 and 2017. In the USA, Jeffrey Dahmer murdered 17 males between 1978 and 1991. Dahmer was captured in 1991 and sentenced to 16 life terms. He was killed by fellow prison inmate Christopher Scarver in 1994.
A serial killer is typically a person who murders three or more people, usually in service of abnormal psychological gratification, with the murders taking place over more than a month and including a significant period of time between them. Different authorities apply different criteria when designating serial killers and, wgile most set a threshold of three murders, others extend it to four or lessen it to two.
For example, the Federal Bureau of Investigation (FBI) defines serial killing as "a series of two or more murders, committed as separate events, usually, but not always, by one offender acting alone".
