A house fire that took place in Brooklyn on Tuesday killed a woman, her daughter, and another child and left another child severely injured, according to the police. It appears that the fire was fueled by the ingredients of a vaping product that the children’s father was making in their apartment to sell. The cause of the fire is still under investigation, but investigators found a substance used to make vaping products, which the father had been using to make items for sale. The father suffered burns to his hands, but he is expected to survive. The family had lived in the home for at least four years, and the cause of the tragic event is believed to have been a homemade product made using a flammable substance. This is one of several deadly fires that have occurred in New York City over the last few days. The authorities are urging people to use caution when handling flammable materials in order to avoid unnecessary tragedies.
