PHOTO: A portable fire pit led to a house fire in Madison on Sunday morning. The Madison Fire Department said dispatchers received a call at 8:23 a.m. for reports of a structure fire at 625 Emerson St. near John Nolen Drive. Firefighters arrived about two minutes later. Firefighters said the family left their portable fire pit on overnight in the back deck outside. The manufactured fire pit was made of metal and had a screen. Officials said the cause of the fire was likely from an ember that landed on the side of the house. Authorities said a neighbor noticed that the back of the house caught fire and called 911 after alerting the homeowners. The family was still sleeping, as there was no smoke inside the house.
