Neighbors said the family — which included six kids, two parents and a grandmother — moved into the home in the Cobblestone neighborhood about a year ago, according to KFOR. Mike Bernard, who lives nearby, said he watched firefighters put the toddlers in separate ambulances at the "disturbing" scene while they performed CPR, according to KFOR. He said he had met some members of the family prior to Thursday's incident, but not the twins.
