Starting in January of 1984, innocent people in the city of Aurora, Colorado were brutally attacked by a man whose weapon of choice was a hammer. Of the eight victims, incredibly, four survived.

Lives and families were torn apart forever and for decades this case would go cold. That is until 2010 when DNA was discovered and would point to someone that was already in prison for similar crimes. But is the evidence enough to officially charge him and bring justice to the victims in Aurora? 30 years later, this mystery is still unsolved.
