SENTENCE
1 HIS HONOUR: On 10 September 2009 the offender was convicted of two counts of manslaughter, pursuant to s 23A of the Crimes Act 1900, i.e. in respect of each of the deceased, the offender made out a defence of substantial impairment by abnormality of the mind. The deceased were her children, Joshua (5) and Jade (3). The verdict was arrived at after a three-day trial before myself as the tribunal of fact (Regina v Nguyen [2009] NSWSC 918). These remarks on sentence should be read with that judgment.
2 The issue before the Court was whether the offender had established that she was suffering from a mental illness as that is understood in s 38 of the Mental Health (Forensic Provisions) Act 1990 in respect of each count (for which the offender was contending) or whether she had made out a defence of substantial impairment by abnormality of the mind under s 23A of the Crimes Act (for which the Crown was contending).
3 It was accepted on behalf of the offender that because the matter proceeded to trial, she was not entitled to a discount for a plea of guilty. Nevertheless, it should be noted that considerable agreement had been reached between the offender and the Crown, which significantly narrowed the issues to be decided. This enabled the matter to be completed expeditiously with a commensurate saving of time and resources.
4 I do not propose to set out the factual background in great detail. This has already been done in the earlier judgment.
5 The offender was born in June 1978 and is of Vietnamese origin. Her early years appear to have been unexceptional and she was part of a loving and supportive family. She and her two sisters were reasonably close.
6 She met her husband in 1998 and married later that year. Because her parents did not approve of her husband, a formal wedding did not take place until 2001. At the time the offender met her husband she was studying at the University of Western Sydney. After the marriage, she ceased those studies and commenced fulltime employment.
7 The offender's first child, Joshua, was born in March 2003. Joshua was a difficult baby and required a lot of attention. The offender felt that she received little support from her husband in relation to Joshua. Her second child, Jade, was born in 2005. Once again the offender felt that her husband did not provide much support for her after Jade was born.
8 After the birth of Jade, the offender remained at home looking after both children while her husband went to work. The offender said that she was happy being a mother but at times felt that she was not coping because of the demands of looking after the two children and because she was receiving little assistance from her husband. When she told her husband about her difficulty, he said that she complained too much.
9 By 2007 the relationship between the offender and her husband had deteriorated. He used to sleep in a separate bed and used to go out on his own at night and would not tell the offender where he was going. In January/February 2008 the offender's husband began to go out at night more frequently and the offender suspected that he was seeing another woman.
10 It was at about this time that the offender found it more difficult to cope. She was having difficulty sleeping, she lacked energy and she had little appetite. She lost weight. She used to cry frequently. She had to force herself to do things. Nevertheless, she was able to look after the children and attend to her housework.
11 During the first half of February 2008 a number of events occurred which confirmed for the offender that her husband was seeing another woman. On the weekend before the death of the children, the offender obtained a voice-activated tape recorder and placed it in her husband's car. When she retrieved the tape recorder from the car, the offender believed she could hear her husband talking and laughing with another woman.
12 The offender became upset and on the evening of Sunday, 17 February confronted her husband who was lying on his bed. She accused him of being unfaithful to her. She was so upset that she broke some of their wedding photographs. Her husband responded by telling her that their relationship was over and that he was going to see her parents and tell them.
13 The other events of that Sunday night are difficult to determine since the offender gave slightly different versions to the psychiatrists who examined her. What is clear, however, is that at some point there was a physical confrontation between the offender and her husband in the course of which she pushed him and he slapped her with some considerable force. A childcare worker observed a cut on the offender's cheek the following morning.
14 The offender did not sleep that night. She felt that her husband had abandoned her. She did not know what to do or how to get out of the problem.
15 On Monday, 18 February the offender took Jade to day care and Joshua to school. During the afternoon she contacted her brother-in-law and asked him to help her follow her husband that evening. She wanted to confront the woman and her husband together. Her brother-in-law agreed to help her. On the way home, she stopped at the supermarket and bought some rat poison.
16 That evening her husband returned from work at 6pm and took a shower. While he was in the shower, the offender took her children and met with her brother-in-law who was waiting outside. When her husband drove off, they followed. After about ten minutes they lost sight of his vehicle. After unsuccessfully searching for the vehicle for some time, they returned home.
17 Because the offender did not give evidence, the only evidence which the Court has about her state of mind at this time comes from the histories which she gave to psychiatrists who examined her and from three letters which she left. The histories given to the psychiatrists are generally consistent, although they do differ as to detail and as to the precise sequence of events.
18 On the morning of Tuesday, 19 February the offender spoke to her husband again and told him that she did not want to end the relationship. He replied that he was sorry for the children but had to leave as he said he did not want her any more. The offender asked him how long the affair had been going on to which he replied that she did not need to know. When the offender asked him if he still loved her, he did not answer and walked out of the room and left for work.
19 The offender said that her husband was a very determined man and after that conversation she was certain that he had made up his mind to leave. After he went to work that day she thought, "I don't want this life" and said that she decided to commit suicide.
20 Sometime later that morning she decided that she had to kill her children as well. She divided the rat poison she had purchased the day before into three and mixed it up in a blender with sugar and water. She thought that this might make it easier for the children to swallow. The following description of what then happened was recorded by Dr Allnutt in his report of 17 August 2009:
"She gave Joshua the poison and told him "it is just a little bit of hurt and we are out of this world, mummy will be there"; Joshua refused to take it, she put him down to sleep.
Jade woke up and she put a pillow on Jade's face, she was not sure how long for, all she was thinking was "just die", "it is too painful to live"; Jade stopped breathing; she stated "I told her I'd be there for her"; she put Jade back to bed.
Joshua woke up, she covered his nose with her hand and he stopped breathing; she told him "just a little bit of hurt and it be over".
She put both of them in the bed and took the poison herself and then laid down beside them;"
21 The precise cause of the children's death could not be ascertained as a result of the post mortem. It was accepted that the most likely cause in each case was asphyxiation (i.e. suffocation).
22 When the poison she had consumed did not appear to be working, the offender took a blade and cut her wrists and waited but nothing happened. She cut herself again and still nothing happened. She then tried to hang herself by putting a loop of rope around a door bar. When she placed her weight on the door bar, it broke. She then consumed all the tablets she could find in the house and lay between the children. She started vomiting. She went back to lie between her children and could not recall what happened thereafter.
23 The offender's husband arrived from work at about 6.15pm. He noticed a trail of blood droplets on the kitchen floor leading to the master bedroom. Inside the master bedroom he saw the offender lying on the bed motionless with the children on either side of her. All three were partially covered by a doona.
24 When ambulance officers arrived, they were unable to revive the children. The offender was observed to be conscious but not responsive. She was observed to have lacerations to both wrists and both inner elbows. She was taken to Liverpool Hospital and has remained in custody at Silverwater Women's Prison under psychiatric supervision since that date. She has been diagnosed as suffering from a severe depression. In approximately May 2009 the other inmates learned of what she had done and as a result of threats, she was placed in protective custody where she has continued to date.
25 Three handwritten letters were located in a top drawer of a bedside table by the side of the bed in the master bedroom. One letter was written in English as follows:
"19/2/08
To whom it may concern
I Nguyen, Thi Truong. I am going and taking my kids with me. However, all my life is a drama. My husband created it and now he made me miserable.
If I and my kids are going the only thing I want from his share from being a wife for many years - is every cost of my funeral and my kids. This is my only wish.
However I want my parents and family in charge of the funeral.
Thankyou. I only want to go peacefully.
Thankyou again.
Thi Truong Nguyen."
26 The second letter written in Vietnamese was as follows:
"Dad and mum
This is the result of me not listening to you, I don't want to die and leave my children lonely in this life but the reality is I do not want to bring them into this life and then have to take their lives away by my own hands, but dear parents I cannot live in this life. If I continue living perhaps until certain days I can not control myself and I have to pour everything to my two children and they are the ones who have to suffer. Please forgive me. Don't be sad because of me lets treat this as a way to release me and my children. I know mum has suffered a lot. I'm sorry mummy, don't think this is a big loss because I am a stubborn daughter. Just think this a life path.
Signed daughter of dad and mum
Younger sister of my sister
Older sister of my younger brother and sister
Please bury my children and myself close to each other, do not cremate."
27 A third letter, also written in Vietnamese was as follows:
"Darling
You have taken me into this life today and you yourself have taken away my life. I only wish to have a lover who truly loves me, think of me and concern about me, understand me a little bit. But eventually it has never been fulfilled. Probably it's my destiny, being husband and wife for a number of years [you have been so cruel to me] [you have treated me badly while I have sacrificed all just for you]. Whatever I have done was for you because of that, how frustrated I have been suffered! Probably, I might not control myself one day. This is the result of what is happening today because of your coolness to me. If you didn't love me why did you live with me. I don't want to take away my children's lives and I also don't want them to live lonely by themselves. Do you know that they have been sad and cried do you know why, because they are not close to their father who used to love them. Life without love (unable to be translated) I have to go away because I don't want to witness the situation in which my husband betrayed me for living with another person. I take away my own life so I don't want to witness the situation in which my children live lonely by themselves and the situation which my husband who is in love with another person. I have been given two wonderful children by God. I don't want to take away their lives because I am the one who have brought them into this life. However what is this life. Living without love, to me life is just only selfishness and betrayal. Let my children and myself leave in peace. This is the last words of a person who in fact is a wife but not a wife.
Truong."
28 In March and June 2008 the offender saw a psychiatrist, Dr Nielssen. When he asked her why she had killed her children, she said:
"She did not believe her husband loved the children and that she did not want to leave them behind without her. … She denied killing the children as a way of expressing her anger towards her husband and said that she did not believe he loved the children as much as she did."
29 Dr Wilcox, psychiatrist, saw the offender on 23 February 2009. In relation to why she killed the children, she told Dr Wilcox:
"At the time she believed that her husband did not love the children because he had chosen the other woman. I observed that at this stage interview she became quite visibly upset and teary. She said that she had thought of leaving her husband and taking the children but then the children would be without their father.
…
She decided that when she died that she would also have to take the children's lives because she could not leave her children without a father. Her whole focus was on the fact that he was leaving. She told me that she felt scared that if she left her husband and had to look after the children on her own she would not be able to control her anger and could possibly harm her children and they would suffer and she decided that if she took their life she would stop them from ever having to suffer. She seemed to be unable to comprehend that her children would have still had a father …
She denied that her actions were in any way driven by a desire to punish her husband. She again told me that she believed that she could not live without him however she could not explain why she felt she could not live without him."
30 Dr Allnutt, psychiatrist, saw the offender on 22 and 29 July 2009 and recorded the following history:
"She began to think about killing herself and the children; she did not want her children to live without a father; she realised that she and her husband would have to separate; she said that she had seen many families break up and it was the children who had suffered; at the time she believed the children were dependent on her; if her husband went with another lady then they would not have a father; she said at the time she would not accept his going to another woman; she could not accept a husband who had betrayed her; at the time she felt that life was worthless in general because the person she trusted had betrayed her; she thought her husband did not want them (she and her children) because when she had asked him whether or not they could stay together for the sake of the children he had said no.
…
The times she gave the children the poison she was thinking "I didn't want them to suffer, this world was lies and betrayal". "I couldn't think anything more".
…
She had in the past had the experience of other families separating with ongoing conflicts between the parents; she said she did not want her children to experience that; she also thought that one day she might "get crazy" and "put anger" on the children and in this sense "they might suffer"; she thought she needed to get out of this world, she thought the only way to do this was to die; she wanted to kill her children because she did not want them to suffer; she thought at the time "life is very cruel", she thought even though she had tried her best to be a good person and a wife, all she got was betrayal and lies; at the time she thought killing herself and the children as a way to escape from "a cruel life"; at the time she believed her children were going to have a "cruel life" because of "what I've been experienced", she said that the minute her husband said "sorry for the children" and he had to get out "it makes me feel pain for the children and their loneliness"; she thought he would abandon the children because of what he had said; a few days prior he had been yelling at the children because he was going to be late which meant to her at the time that the children were not his first priority".
