Fewer than twelve hours after her body was found and without any evidence, police decided a married couple from Denver had killed her.

In the summer of 1995, at the largest Boy Scout camp in Ohio, a night of sexual violence ended with one counselor dead and another hospitalized. The death was ruled "accidental."

He was always sure there must be more to the story of Mike Klingler's death, because Renner also knew firsthand that the 900-acre camp was not the safe getaway it was portrayed to be.
