24-year-old Andy Cash was charged with the three murders and was remanded in custody.
A man accused of murdering his two sisters and brother in Tallaght in Dublin has been further remanded in custody.
Andy Cash of Rossfield Avenue was charged with the three murders last September.
In the early hours of September 4th last year, 18 year old Lisa Cash, and her eight-year-old twin brother and sister, Christy and Chelsea Cawley, died after they were attacked and stabbed at their family home in Rossfield Avenue, in the Brookfield area of Tallaght.
24-year-old Andy Cash was charged with the three murders and was remanded in custody.
The DPP has directed trial on indictment in the Central Criminal Court, but, the State must complete a book of evidence and serve it on him before being granted a trial order.
He appeared again at Cloverhill District Court today.
Judge John Brennan agreed to grant a three-week adjournment until March 24 for a book of evidence to be served on the accused.
The District Court cannot grant bail in a murder case which requires a High Court application.
