Melanie Smith who murdered five members of a family, including three young children, when she set fire to her neighbour's pushchair at a flat in Prestatyn has been jailed for at least 30 years.
The 43 year-old, started the devastating blaze because she was angry the pushchair had been left in a shared hallway.
Lee-Anna Shiers, 20, her four-year-old nephew, Bailey, and two-year-old niece, Skye, were trapped in their upstairs flat and died in the attack in October last year.
Firefighters managed to rescue Ms Shiers's 15-month-old son Charlie and his father Liam Timbrell, 23, but they died in hospital.
Smith, who lived in the flat below the victims in Maes y Groes was found guilty of five counts of murder by a jury at Mold Crown Court last Tuesday.
