When murderers stalk the streets of a city, the climate of fear means no one wants to go out alone, especially at night. Infamous Murders examines three modern day serial killers who found their victims - usually lone females - on the streets of British and American cities.

The Yorkshire Ripper earned his nickname from his frenzied attacks on prostitutes and young girls in Leeds in Northern England in the 1970s and 1980s.

As the death toll mounted, more than 300 police officers were employed on the greatest manhunt ever conducted in the UK. Finally the police were led to Peter Sutcliffe, a 34-year-old truck driver, who claimed he was ordered by God to carry out the killings. Sutcliffe was sentenced to life imprisonment.

The prostitutes who worked the streets of New York in the early 1990s were subjected to a killer who confessed to killing seventeen women over a four-year period.

Joel Rifkin was a loner, who strangled his victims and dismembered some of the bodies before discarding the pieces in the Manhattan waterways. He was jailed for life after being found guilty of murdering ten prostitutes.

Several years earlier, the New York streets were the hunting ground for another prostitute-killer. Arthur Shawcross had murdered a child many years earlier, and after being driven out of a couple of small towns he settled in New York, where he could be lost in the throng of the busy city streets.

Shawcross picked up prostitutes and drove them out into the surrounding countryside, where he killed them. He then mutilated and hid the corpses, and even claimed to have eaten some of the body parts. But the Rochester Police caught up with him, and he was sentenced to 250 years in jail, without any possibility of parole.
