Pills in juice: Mother told psychiatrist chilling account of killing children

She mashed up the sleeping pills in fruit juice and offered it to her children, who drank without protest.

As the drowsiness set in for Minu Jo, 6, and Yuna Jo, 8, they 鈥渢oddled off鈥 to the bedrooms of their Papatoetoe, South Auckland, home.

Hakyung 鈥淛asmine鈥 Lee, 45, then took what she thought would be her own fatal dose of the same drug, but she woke up about 24 hours later still alive.

The bleak account of her children鈥檚 deaths was recently revealed for the first time to psychiatrist Yvette Kelly, who entered the witness box in the High Court at Auckland today as the defence鈥檚 only witness in Lee鈥檚 double-murder trial.

The account came after years of Lee denying all responsibility for her children鈥檚 June 2018 deaths. It was a slow revelation and at times like getting blood from a stone, Kelly said with a laugh.

鈥淚 don鈥檛 think when she saw me she was planning to tell me the story,鈥 Kelly later explained. 鈥淚t was a slow, difficult thing. I suspect it was really her admitting to herself at the time what had happened.鈥

Lee - who then hid the children鈥檚 bodies in suitcases, changed her identity and moved to South Korea - has pleaded not guilty by reason of insanity.

In such cases, the onus is on the defence rather than prosecutors to prove a defendant was so mentally unwell at the time of the killing that he or she didn鈥檛 know what they were doing was morally wrong. Lee meets that criteria, lawyer Lorraine Smith told the jury this morning.

The defence-called psychiatrist then expanded on the idea.

鈥淗er thoughts were such at the time that she thought the act was the right thing to do by her children,鈥 Kelly explained.

Lee told Kelly that killing her children happened spontaneously, even though she had been having suicidal thoughts for over a year as her husband was diagnosed and then died from cancer.

鈥淪he just decided this was the time she wanted to die and the children should come with her for her well-being,鈥 Kelly recalled being told. 鈥淪he described the deaths of the children as secondary to her own death.

鈥淭heir death was not the goal. Ms Lee described her own death as the goal.鈥

Upon waking up the next day, Lee told the psychiatrist, she went to check on her children and realised they were non-responsive. The health professional asked her why she didn鈥檛 call for help.

鈥淎t that point, she didn鈥檛 want them to be revived,鈥 Kelly recounted. 鈥淪he just wanted to die herself.鈥

Lee told the psychiatrist she tried to overdose a second time with the leftover pills but woke up again the next day. It鈥檚 not unusual, Kelly emphasised, for people to often fail at suicide when dealing with pill dosages.

The defendant reported that she then tried to hang herself with a phone charger cord but the knots wouldn鈥檛 hold and she considered getting into a one-vehicle car crash.

鈥淲hy didn鈥檛 you do it?鈥 the psychiatrist recalled asking her.

鈥淚 wasn鈥檛 convinced that it would kill me,鈥 the defendant allegedly responded.

The psychiatrist added: 鈥淚 think at that point she was starting to get a little concerned about the repercussions of her children鈥檚 deaths.鈥

Lee said she considered turning herself in but was afraid of going to prison.

As for why she put her children鈥檚 bodies in suitcases then abandoned them in storage, Lee said she didn鈥檛 have a plan or know what to do.

鈥淪he wanted to bury the children but she didn鈥檛 know how she could achieve that,鈥 Kelly told jurors. 鈥淪he鈥檚 now relieved that the children have been buried with her husband rather than in the storage facility.鈥

Lee said she changed her name only because 鈥渟he wanted to erase everything about herself ... due to her own self-loathing鈥.

After several suicide failures, Kelly said, it appeared Lee decided to 鈥渢ake a break鈥 and try again once in Korea. But while there were other attempts over the four years before she was extradited back to New Zealand, they also failed, the psychiatrist was told.

Asked in retrospect if she regretted what occurred, Lee said she wishes it had been her who died and not the children. But she couldn鈥檛 come up with 鈥渁n alternative story as to what she could have done鈥, the expert witness said.

鈥淪he says she now sees that killing the children was the wrong thing to do ... but at the time she felt it was the right thing to do,鈥 Kelly said.

Kelly diagnosed the defendant as having a major depressive disorder that led to not being able to tell her actions were morally wrong. She stressed that people can understand things are legally wrong but still believe they are doing the right thing.

Crown solicitor Natalie Walker began to cross-examine the psychiatrist just before the jury鈥檚 lunch break. That cross-examination is expected to continue this afteternoon.
