Temperatures that topped 110 degrees are suspected of causing the deaths of two people in Yuma County.

Sheriff's spokesman Capt. Eben Bratcher says a bus driver spotted the body of a 69--year-old man in a field near U.S. Highway 95 on Monday morning. The transient is believed to have died of heat-related causes.

Deputies were later called to a home in a Foothills neighborhood east of Yuma after an 80-year-old woman was found dead in her apartment.

Bratcher tells the Yuma Sun that a friend went to check on the woman and found her dead. He says it was 105 degrees in the woman's apartment and the air conditioning was shut off.

Temperatures have topped 110 degrees across much of Arizona deserts for the past two weeks.
