For years, an elderly man stood as a regular fixture around his East Baltimore neighborhood for the way he would wander the streets in the summer, trying to stay outside his sweltering home until nightfall.

This man, who suffers from dementia, lived in a row house that shared side walls with its neighboring homes. With windows only in the front and back, there was little air flow, which trapped the heat inside. It’s not unusual for the upper floors in such homes to be several degrees hotter than the temperature outdoors.

During a nearly two-week heatwave that swept through the city in July 2019, Cynthia Brooks, executive director of the Bea Gaddy Family Center, a local non-profit that provides food and other services for the poor and homeless, noticed she hadn’t seen the man for a while. Finally, on one of the “code red” days – when the forecasted heat index is expected to be at 105F (40.56C) or higher – he stumbled out of his house, looking disoriented. No one knows how long he had been sitting inside, alone, without a fan or air conditioning.
