Twenty years ago, Anu Singh held two dinner parties to say goodbye to her friends. She divulged that she and boyfriend Giuseppe โJoeโ Cinque had a suicide pact โ except it turned out Joe knew nothing about it.
The twisted crime became notorious for its chilling cruelty, and last night, Anu spoke to Sunday Night in an attempt to explain herself.
โOne of the biggest things was, I was suffering from a very, very severe mental illness at the time. If I could have listened to people and sought the right sort of mental help, this wouldnโt have happened,โ she said.
On October 26, 1997, the young lawyer spiked her boyfriendโs coffee with Rohypnol before injecting him with a lethal dose of heroin. She called an ambulance 36 hours later and gave the ambulance the wrong address to delay their arrival.
On the program, she gave a chilling description of the moment she injected Joe with a fatal dose of heroin.
โIt was me straddling his body and the paramedics saying heโs gone and me not wanting to believe it at all.โ
Forensic psychiatrist Professor Paul Mullens, who assessed Singh for the court, supported her claims of her severe mental illness but made sure to clarify she knew the difference between right and wrong.
โThis was a grossly disordered woman with a mental illness. She was mad. Not totally mad, she knew what she was doing up to a point. She knew it was wrong up to a point, she could have controlled herself up to a point, but she wasnโt in a normal state of mind,โ said Mullens.

In the lead up to Joeโs death, Anu was battling a severe eating disorder and blamed Joe for her addiction to the weight-loss drug Ipecac.
โShe began telling people, friends, that she believed Mr Cinque had given her something which had poinsoned her and this is why she was now dying of this strange degenerative disorder, of which she thought she had,โ Mr Mullens explained.
โShe was depressed and disorderedโ
Detective Sgt Greg Ranse, who worked on the case, revealed that Anu had asked around for where to buy a gun and, when that proved too difficult, procured heroin instead.
Det. Ranse is sceptical of Singhโs โdiminished responsibilityโ charge. โShe has fooled everyone. Well, she hasnโt fooled everyone โ she certainly fooled the courts,โ he said.
โShe wants to see herself as the victim in this. Sheโs the victim. Sheโll always be the victim in her own mind, but in reality, itโs the Cinque family thatโs the victim in this.โ
The program also focuses on the complicity of the friends involved in the dinner parties.
โOne of the most awful aspects of the case. I mean, not just indifference, but looking at the evidence, one wonders if they werenโt almost pushing and provoking her. I mean itโs inexplicable,โ said Mr Mullens.
โThis will sit in the minds of people and the public of how a person could morally justify themselves,โ said Det. Ranse.

Now 44 years old, Anu told Sunday Night sheโs desperate to โturn back the clockโ.
โThere are many things people donโt understand,โ she says.
โItโs just awful being referred to as a killer, a murderer.โ
Anu spoke to Sunday Night on the condition they show her apology to Joeโs parents, Maria and Nino.
But his parents remain stupefied that despite confessing to the killing, Anu was only sentenced to ten years for manslaughter due to โdiminished responsibilityโ โ of which she only served four.
โI would ask her, why you really killed him,โ a visibly upset Maria says.
โDonโt tell me this bulls-t aboutโฆ you didnโt know what you are doing because I donโt believe you.
โI never, ever forgive her for as long as I live.
โShe better not come near me, I never ever forgive her,โ Maria continued.
โI call you the devil and you are the devil. Monster, you have destroyed my family. You have killed the most precious thing I have in my life. I donโt want to see your face anymore โ go away.โ
