On the night of July 13, 1977, a citywide power failure plunged New York’s ten million residents into darkness. Chaos ensued. There was looting in every borough, with hundreds of fires set and thousands of arrests — but just one murder. The victim was 17-year-old Brooklyn native Dominick Ciscone.

Over 40 years later, the Ciscone case is still unsolved, despite multiple witnesses, decades of police attention, and even some anonymous tips. Because that murder might not have been part of the Blackout’s chaos at all — it might have been planned, not by someone who anticipated the power going out, but by someone who saw an opportunity to kill in the dark.
