Melissa Kingston-Lee with her dog Bruce and mother Rebekah Kingston-Lee outside her house that was burnt down after an alleged arson attack at Christie Downs. Picture: Calum Robertson "The heat was was so intense it shattered the glass in the living room window and the curtains went up," she said. It was so scary. If it wasn't for the smoke alarms I would have lost my kids .... it happened so quick. The four children, aged 6, 7, 8 and 10, escaped without injury along with a 17 month-old baby and Ms Kingston-Lee's partner who were asleep in the bedroom. Picture: Sam Kelton "The kids are safe but I don't think they know what has happened," she said. We've lost everything. Our cat Missy was inside and the firemen told us this morning that she didn't make it out. It doesn't make sense - I don't now why someone would do this. I could have lost my kids - I hope they catch whoever did this and the person realises what they've done. The family are hopeful neighboring CCTV cameras will hold the key in identifying the arsonists responsible for the blaze. "Police were looking at it last night and I hope it helps them find who did this," Ms Kingston-Lee said. Arriving at her nearby mother's house - shortly after 3am - Rebecca Kingston-Lee said it was horrible to see her daughter on her doorstep saying she had lost everything. "It's terrible news to wake up to," she said. I can't believe this has happened. We're just so lucky the kids made it out. Ms Kingston-Lee and her partner did not have insurance and damage is estimated at $150,000.
