As Wednesday, July 13, 1977 dawned hot and humid, New Yorkers prepared themselves for another sweltering day. It was the first day of a nine-day heat wave that would become the hottest in New York City history. The once-booming city had been suffering years of economic decline. It was on the verge of bankruptcy; both unemployment rates and crime rates were high; police and firefighters had been laid off; municipal services, including sanitation and after-school programs, had been cut; and a serial killer named Son of Sam was still on the loose, keeping everyone on edge.When a severe thunderstorm hit, the lights went out, and some eight million people plunged into darkness in New York City and surrounding areas. By the time the power was fully restored more than a day later, more than 1,600 businesses had been looted, more than 3,000 people had been arrested, and firefighters had battled more than 1,000 fires. The affected neighborhoods would never be the same.
