Urantsetseg Tserendorj died after she was stabbed in a 40-second incident in the IFSC.
The boy, who cannot be named because he is a minor, appeared again at the Dublin Children’s Court. Earlier that court ruled that other alleged offences could be included in the murder trial after the State argued they demonstrated a pattern.
Urantsetseg Tserendorj, 48, originally from Mongolia but who lived in Dublin with her family for a number of years, was rushed to the Mater Hospital following an attack on Jan. 20 last.
The incident happened at 9.30pm near the CHQ building at Custom House Quay as the office cleaner walked home from work.
She remained in a critical condition for two weeks before she passed away with her husband Ulambayar at her bedside.
Judge Paul Kelly further remanded the teen custody to appear again on July 21 next.
He was aged 14 at the time of the incident and was originally charged with assault causing harm, attempted robbery and unlawful possession of a knife as a weapon.
However, last month the case was upgraded. The assault and knife possession charges were withdrawn on direction of the Director of Public Prosecutions (DPP).
They were replaced with charges of murder of Mrs Tserendorj at the walkway between St George’s Dock and Custom House Quay, and production of a knife while committing murder.
The teen was also charged with other offences on the same date as the murder, and one offence two days earlier: a robbery of a woman close to the IFSC, a threat to kill or cause serious harm to a shopkeeper on O’Connell Street, and production of a knife while attempting robbery of a third woman at Amiens Street in Dublin 1.
Detective Sergeant Brendan Casey told the court the incident involving the deceased, Urantsetseg Tserendorj, lasted 40 seconds.
She had left work in the IFSC and was walking home.
It was alleged the boy threw his bike in front of her and demanded money. It was claimed the teen “produced a knife and inflicted a single stab would under her ear”.
It was alleged that following a brief verbal interaction, the teen left while Ms Tserendorj phoned her husband. They met at Amiens Street and an ambulance was called.
The teen has not yet indicated how he will plead.
A book of evidence has to be served on him by the State before an order is made sending him forward for trial to the Central Criminal Court.
