Authorities say a woman set a fire that injured herself and two children earlier this year in Webster.According to the New Hampshire State Fire Marshal's office, Mary Corliss said the fire was started by a dog who knocked over a candle, but they said the evidence doesn't support that.Investigators said the fire on Deer Meadow Road in February started in a second-floor bedroom.According to the affidavit, one of Corliss's children told an EMT, "When the bad guys broke in, my mom set the fire to protect us."As for the claim by Corliss that the fire started when a dog knocked over a candle, investigators said the dogs were downstairs and blocked from getting to the second floor.They also believe that Corliss tried to blockade herself and the children in, noting a headboard leaning across the top of the stairs.After everyone was rescued, when Corliss was being taken to an ambulance, she allegedly struck the officer carrying her, saying, "I've taken Wormwood," "My body is poisoned" and" "You'll die if you eat me."Corliss and her two children were taken to the hospital and treated for smoke inhalation. One child was also treated for burns.During the investigation, investigators said they recovered a lighter beneath the window where Corliss was located.The affidavit also said that Corliss admitted to having used turpentine to ward off COVID-19, and when questioned about the possibility that it might have poisoned her, causing her to believe things that weren't real, she admitted that was possible.Corliss pleaded not guilty to the five charges against her, which include arson, two counts of reckless conduct and two counts of endangering the welfare of a child.Corliss is currently free on bail but has been ordered to stay away from her children.
