Officials say 90-year-old Joseph Kuzmak had been in Lehigh Valley Hospital-Cedar Crest since he and his wife were found in their Weisenberg Township home Monday.
Lehigh County Coroner Scott Grim said Kuzmak died at 4:35 p.m. Wednesday at the hospital. Ninety-year-old Lillian Kuzmak had been pronounced dead at the house. Officials said the air conditioning wasn't turned on and it was about 100 degrees in the home.
Their son, James, told the paper that the couple had been married for 69 years.
Officials have said that the heat wave was a factor in the deaths of at least nine Pennsylvania residents.
