An elderly couple have been found dead in their bedroom after their heater was estimated to have reached 538C (1,000F).
Joan Littlejohn, 84, and Glennwood Fowler, 82, were found in their South Carolina home on Saturday evening, with police recording the temperature of the property sitting at around 49C (120F) even 20 minutes after they had opened the windows and doors to let colder air in.
The discovery came three days after the couple had complained that they were having trouble with their heating.
Police said the couple told their family on Wednesday that their heating system and water heater were not working, so family members visited and thought they had fixed the problem.
The family members contacted police three days later, having not heard from the couple since their visit.
A paramedic found the bodies in the bedroom after entering through an unlocked window, authorities said.
The paramedic couldn’t accurately measure the body temperatures of the couple, because of the device’s maximum measurement of 41.1C (106F).
