An autopsy is scheduled for Thursday, to determine the cause of death of a man in Milwaukee.
The Milwaukee Health Department suspects three residents may have died from heat-related causes. The city and state were submerged in hot, humid conditions much of the week.
Investigations are underway in all three deaths to confirm the causes.
The health department continues urging people to check on those who may be trapped in a hot home, and to be aware of symptoms of heat-related illness: dizziness, fainting, headache or nausea.
