SINGAPORE , Nov 9 — A domestic worker accused of stabbing her employer’s 70-year-old mother to death began standing trial for murder in the High Court on Tuesday (Nov 9).

Zin Mar Nwe, a Myanmar national, was thought to be 23 years old at the time of the incident in June 2018.

But investigations later revealed that she was actually 17 — corroborated by a bone-age test conducted by Tan Tock Seng Hospital — and her agent had told her to lie so that she could meet the minimum age of 23 to work as a maid in Singapore.

Zin Mar Nwe now faces a single charge of murder under Section 300(c) of the Penal Code which carries either life imprisonment or the death penalty.

The petite woman appeared in court on Tuesday dressed in white prison garb, having been in remand since June 25, 2018 when the alleged murder took place.

Prosecutors said she had confessed in statements given to police investigators that she killed the victim by stabbing her repeatedly.

Allegations of abuse

On May 10 that year, she started working for her employer and his family which included his wife and two teenage daughters.

Due to a gag order imposed by the courts to protect two trial witnesses, the identities of the employer and his family, along with the exact location of the flat in Chua Chu Kang cannot be published.

Zin Mar Nwe primarily took care of the household chores, laundry and cooking.

In their opening statement, Deputy Public Prosecutors (DPPs) Kumaraesan Gohulabalan and Sean Teh told the court that Zin Mar Nwe would wake up at about 5.30am and go to bed around 11pm.

She could call her relatives in Myanmar, and in her statements to the police, she said she had no complaints about the family or her working conditions. She was paid S$450 every month, part of which went towards her repayment of a loan to the maid agency.

Her employer’s mother-in-law arrived from India on May 26 that year and planned to stay with the family for a month.

The case’s investigation officer testified in court on Tuesday that Zin Mar Nwe claimed the older woman had physically abused her several times behind the family’s back.

These allegations included telling her to perform various tasks, scalding her with a heated pan, hitting her on her head or body using various pieces of crockery or her hands, and kicking her on the chest when she was cutting the older woman’s toenails.

The investigation officer added that Zin Mar Nwe said her employer’s daughter was occasionally in the unit but not in the same room when the abuse occurred.

However, a subsequent medical report did not show any injuries on Zin Mar Nwe that could have arisen from the alleged abuse.

Accused said victim told her: ‘tomorrow, you go agent’

On the day of the killing, the maid was alone with the employer’s mother after the rest of the family left the home at 11.30am.

Between then and about 12.15pm, Zin Mar Nwe claimed that the other woman became upset with her and told her loudly: "Tomorrow, you go agent.”

"When the accused heard this, she felt ‘angry’. She grabbed a knife with her right hand and stabbed the deceased repeatedly, until the deceased stopped moving. The accused observed that the deceased tried to push her back but was unable to do so,” the DPPs told the court.

The investigation officer further testified that Zin Mar Nwe had told him about her mind being in a blank when she held onto the knife and stabbed the victim, who was lying down on a sofa watching television in the living room.

The victim suffered 26 stab wounds in total.

Afterwards, Zin Mar Nwe ransacked the master bedroom and broke a cupboard lock to retrieve her belongings, but she could not find her passport.

She then washed the knife in the kitchen, left it there, changed into a dress and took some money and a transit card before leaving the flat.

She went to her maid agency nearby and asked for her passport but left when she realised staff at the agent were going to call her employers. She then took public transport to various places including Bukit Merah Central Hawker Centre where she went to eat.

She eventually returned to the maid agency in a taxi at about 5.30pm. Staff alerted police and she was arrested there.

The cabby subsequently found a plastic bag containing S$114 in cash. When he tried to return it to Zin Mar Nwe, she said it did not belong to her, but forensic analysis later found that the bag and notes were stained with her blood.

When she was examined by Dr Alias Ligo from the Institute of Mental Health in 2018 and earlier this year, she was found to have no mental illness that impaired her mental responsibility for her acts at the time.

However, Dr Tommy Tan, who is in private practice, stated in a report last year that she suffered from either mixed anxiety and depressive reaction, or adjustment disorder with mixed anxiety and depressed mood, which substantially impaired her mental responsibility.

This would give rise to a defence of diminished responsibility.

Dr Tan also opined that Zin Mar Nwe was in a dissociative state at the time of the offence.

In response, the prosecution argued that Dr Tan’s diagnosis was solely based on information given by Zin Mar Nwe, and that the accused’s agent’s observation of her that day also contradicted the finding of a dissociative state.

The trial before Justice Andre Maniam continues on Tuesday afternoon. — TODAY
