A "drunk and jealous" woman who repeatedly threatened a neighbour killed a family-of-five in a devastating fire following a row about a pram in a communal area, a court has heard.
It was claimed that Melanie Smith, 42, was drinking heavily on the day leading up to the fire and was heard shouting through the letterbox "I'm going to burn your house down".
Smith and neighbour Lee-Anna Shiers argued for up to two months before the blaze, the court was told.
But the row is said to have intensified over a pram which was left in a walkway outside their flat. Smith is accused of killing the family of five by setting the pram alight.
Ms Shiers, 20, her four-year-old nephew Bailey and two-year-old niece Skye died in the blaze at their home in North Wales on October 19 last year.
Firefighters managed to rescue Ms Shiers' 15-month-old son Charlie and his father, Liam Timbrell, 23, from their first-floor flat but they both died in hospital.
Smith, 42, who lived in the flat below the victims in Maes y Groes, Prestatyn, has gone on trial at Mold Crown Court accused of murdering them.
The court was played a harrowing 999 call in which Mr Timbrell shouted: "Oh my god, oh my god, we're going to die."
The jury was told that Mr Timbrell later told rescuing paramedics that "it was arson" and "it was Mel from downstairs".
Smith denies the five murder charges and also one count of making a threat to destroy or damage property.
