Anu Singh

Dr. Anu Singh (born 3 September 1972) is an Australian of Indian descent. In 1999 she was convicted of the 1997 manslaughter of her then boyfriend Joe Cinque by lacing his coffee with rohypnol then injected him with heroin. Subsequent to her release, Singh has undertaken criminology research. Her story has been portrayed in literature and in film.

Death of Joe Cinque

In 1997 Singh and Cinque were living together in Canberra while she was a law student at the Australian National University. During the 1998 trial, a friend of Singh testified that Singh had been obsessed with her body since 1991 and had briefly taken Ipecac after Cinque mentioned it, something she was later angry with him for. In May 1997 she told a friend that she wanted to kill a number of people, including Cinque and her doctors.

Singh's close friend Madhavi Rao invited acquaintances to two dinner parties in October 1997 and told them that a terrible crime would be committed. Witness Sanjeeva Tennekoon reported that the first dinner party on 24 October was normal and that Singh and Cinque appeared loving. However, another witness told the court that Rao had told her afterwards that Singh had tried to kill Cinque that evening but did not deliver a sufficient dose, and that the witness had threatened to go to the police. The day after the first dinner party, Singh and Rao went to a friend, Len Mancini, and told him they had given Cinque drugs the previous evening.
