A third child has died after being found in an Ohio home with high levels of carbon monoxide . Jakia Jones , 13 , died Sunday after a relative found her unresponsive at her western Ohio home . The teenager was at home with her cousins Dionanna Bishop , 14 , and Dejah Bishop , 13 , who died Friday after they were rushed to an emergency room , according to The Dayton Daily News . Death : Sisters Dionanna Bishop , left , 14 , and Dejah Bishop , 13 , died of possible carbon monoxide poisoning . But as the family come to terms with their tragic loss , Jones ' eight-year-old brother , Jahari Jones , remains on life support at Dayton Children 's Hospital . According to police , a furnace caused the leak of carbon monoxide , an odorless and colorless gas created when some fuels are burned . The children lived with their grandmother , Jean Bishop who was hospitalized with pneumonia Friday . A relative of the dead children reported to police that the kids had been sick for days . All of the children were thought to be home alone when they became ill . Firefighters who initially responded to the home were also treated and released at Upper Valley Medical Center for possible carbon monoxide exposure , said Assistant Fire Chief Matthew Simmons . However , James T. Ambrose , an attorney for Joseph and Kathy Caldwell , a couple who own the home said they were n't aware of furnace problems and did n't know children lived there . They have owned the property for about 20 years and had no indication the furnace may have had a problem . House : Emergency personnel carry a person out on a stretcher from the home in the 100 block of South Elm Street , Troy , Friday afternoon . 'Every time there was a problem in the home , whether it was a leaky faucet of whatever , they attended to it , ' Ambrose said . 'Whenever they were informed of anything , they addressed it appropriately and promptly . ' He added that the Caldwells were devastated over what happened . But police said there will be a thorough review of the case to determine whether any charges should be filed . Preliminary autopsy results on two of the deceased children — sisters Dionanna and Dejah - showed that they died of exposure to carbon monoxide , according to Miami County coroners . Meanwhile the children 's distraught uncle Leon Bishop Sr. , said he 'd spent all-night praying at Dayton Children 's Hospital before losing Jones . ' I 'm numb , ' he said . 'We 're all pulling for the kids in the hospital . We 're all praying . I 'm getting a lot of support from friends and family . ' Shane Carter , director of the Lincoln Community Center told The Dayton Daily News that the children participated in after-school tutoring and recreational programs at the center . He has now planned a candlelight vigil in their memory at 6 p.m. Sunday . Additionally , the center is establishing a fund at Wright-Patt Credit Union to help the family with funeral expenses . 'My hope and prayer is that we can just be able to get the support and the resources needed to send them off the proper way , ' Carter said .
