The recent heat wave has claimed a second victim.
Lillian Kuzmak, 90, of 2203 Apple Road in Weisenberg Township, was pronounced dead in her home on Monday morning.
The Lehigh County coroner says she died of hyperthermia due to excessive heat. Kuzmak's death has been ruled an accident.
Her home has air conditioning but it was not turned on.
"The ambient air temperature in the household was approximately 100 degrees," according to a press release from the coroner's office.
On Sunday, the coroner released information about an elderly Allentown man who died of heat stroke.
This week's weather is expected to be more seasonal with highs in the low 80s and lows in the 60s.
