Philadelphia records its first heat-related death of summer

Philadelphia has recorded its first heat-related death of the summer.

The Philadelphia Inquirer reports that a 57-year-old man died in his northwest Philadelphia home.

City Health Department spokesman Jeff Moran says the man had a box fan running in an open window. He says the house had air conditioning but it was not turned on.

Moran says the man's cause of death was chronic obstructive lung disease, with heat exposure as a contributing factor.

The heat index, which factors in humidity, hit 106 degrees in Philadelphia on Thursday.
