A Carson City woman was arrested after a house fire that left one of her children dead and the other in critical condition. 23-year-old Samantha Paulino told investigators she had left her daughter and son, a three year old and a two year old, home alone. She says it was to register for college classes. A fire was reported at the Shoshone Street home just after noon Tuesday. Washoe Tribal Police were the first to arrive. They had trouble getting into the home right away because there was already heavy fire and smoke. The children were taken to the hospital, where the girl was pronounced dead. The boy is expected to survive. Paulino now faces charges of child abuse causing great bodily harm and open murder. The children’s father was working out of town at the time of the fire.
