This is the first picture from inside the house where four siblings died in a tragic house fire started during their mother's birthday party.

Reece Smith, 19, died trying to rescue his twin sisters Ella and Holly, four, and two-year-old brother Jordan from the flames at their home in Freckleton, Lancashire.

Mother fights tears today as she makes emotional appeal for help catching her children's killer

The fire started inside the wardrobe in the twins' upstairs attic bedroom. It contained the youngsters clothes and toys.

This is the first glimpse inside the charred remains.

Police say the fire was lit deliberately and have launched a murder hunt. Detectives believe someone who was at the party holds the key to solving the case.

Another of her sons, 16-year-old Andrew Smith, had followed his brother into the burning house but was beaten back by the thick smoke pouring from his sisters' room. 

Lancashire Fire Service confirmed that smoke alarms were fitted but were not working when the fire started.

The family allowed the Fire Service to reveal the information in the hope other families would test their smoke alarms to prevent similar tragedies

Ms Smith fought back the tears today as she made a desperate appeal for help to catch the killer of her four children.

Alongside Reece's father, Martin Goulding, she sat below a giant montage picture of them as their Lancashire Police liaison officer read out a statement on their behalf.

Obviously distressed, Ms Smith appeared to be holding back tears as Detective Constable Ian McVittie told a press conference in Blackpool they 'can't understand why anyone would do such a thing and how they can sleep at night with the guilt'..

The statement said: 'Our whole family has been devastated by the fire that took away four of our treasured children.

'Reece was our 19-year-old son, who wanted to be an engineer working on airplanes and was a huge Blackpool fan but overall was a loving son and brother

'The twins, Holly and Ella, were only four years old and were like chalk and cheese and had their own little characters and personalities.

'They had just started enjoying school life making new friends in a big, new world and were due to celebrate their fifth birthday later this month.

'Jordan was the baby of the family. He was only two years old. He made us laugh so much and was always bumping into things so we nicknamed him "Banger".

'All four of them had so much more life to live.'

Detective Superintendent Dermott Horrigan, from Lancashire Police, yesterday appealed to the public for information to help catch the killer

In a statement he said: 'This is a murder investigation into the deaths of four people; a teenage man, his twin sisters and baby brother.

'We have a major investigation team working on a number of lines of inquiry to establish exactly what happened that night.

'It is important that people know that we do not believe that this was an accident.
