PHOENIX (AZFamily) – After a record 645 heat-related deaths last year in Maricopa County, cities and agencies are coming together to reduce the numbers. ASU nursing students are partnering with the City of Phoenix to do their part to help people experiencing homelessness in the Arizona summer heat. Each week, a group of students spends time at Burton Barr Library, Phoenix’s 24/7 respite center, to help care for the people who use the facility.
