NEW YORK (AP) The New York City medical examiner's office says nine people have died of heat exposure during July's punishing heat wave.

The medical examiner's office had confirmed eight deaths but said Wednesday an 84-year-old Brooklyn man died of hyperthermia on Sunday.

In all, four people in Brooklyn, two people in Staten Island and one person each in the Bronx, Manhattan and Queens have died from hyperthermia this summer.

The medical examiner's office has said at least eight of the victims had underlying medical conditions. Their names were not released.

On Friday, a 67-year-old Queens man died and two Brooklyn women, a 61-year-old and an 82-year-old, died on Saturday. On July 8, a 57-year-old Staten Island man died when the temperature reached 89 degrees.
