Just after 2:30 am on December 15th 2000, a man named Steve Johnson and his girlfriend Kim, were at their home in Wichita Kansas when they heard a pounding at their front door. What they found when they opened the door would change their lives forever.. A young woman, nude and bloodied, telling them she and her friends had been shot and begging for them to call 911. This was the final event of a horrific crime spree that spanned over 9 days.
