Eighty-two-year-old identical twin sisters were found dead in their San Antonio, Texas home after the city sweltered through days of 100-degree heat.

The bodies of Florence and Emma Jernigan were found Thursday in the home where they had lived all their lives. Police say the single window air conditioner in the home was off.

Authorities said no one had heard from the women for several days. A neighbor called police after noticing a foul odor. The cause of death was pending but was believed to be heat-related.

The city set or tied heat records four times in the last week of June, topping out at 104 degrees on June 29.

Neighbors say the women never married and lived frugally on a fixed income. They said the two would ignore friends' pleas to turn on the air conditioner or a fan.
