No details of the double murder were given at the hearing A 27-year-old lodger has admitted murdering a Polish woman and her 11-year-old son at their home in Flintshire.
Monika Wasko, 29, and her son Patryk died after a stabbing at their house in Cae Hir, Flint where Krystian Krysztof Rozek had been staying.
Rozek denied the attempted murder of Mrs Wasko’s husband Rafael and the charge will lie on file.
His sentencing was adjourned to a date to be fixed in the future.
Caernarfon Crown Court was told that paperwork for the case was incomplete.
Rozek was accompanied by a female interpreter in court.
Judge Merfyn Hughes QC told him: “Within the next few days you will be informed of the date upon which you will be sentenced.
“You understand of course that the only sentence which the court can impose upon you is life imprisonment.”
Rozek will be sentenced for the double murder at Caernarfon Crown Court on 18 October.
Mr Wasko, 33, has since returned to Poland. Simon Mills, prosecuting, said he did not intend to return to Britain unless absolutely necessary.
The charge of attempted murder was ordered to lie on file.
Full details of the stabbing tragedy which unfolded at the house on Sunday 11 July were not given in court.
Police and paramedics were called to the Waskos’ home in Flint at 0130 BST.
Mrs Wasko, a council cleaner, died at the scene. Her son died in Alder Hey Hospital in Liverpool three days later.
Members of St Mary’s Roman Catholic Church in Flint joined local members of the Polish community to launch a fundraising appeal so that the pair could be returned to their homeland for burial.
The collection was organised by the parent teacher association at St Mary’s RC Primary School in Flint where Patryk was a pupil.
