A terrible statistic: one in six women will be a victim of rape or attempted rape in her lifetime. But an even more shocking reality: A backlog in processing rape kits - crucial evidence in arresting violent predators - is delaying and sometimes denying justice for tens of thousands of American women. NOW travels to Los Angeles County to investigate why it has the largest known rape kit backlog in the country -- over 12,000 kits are sitting untested in police storage facilities. An internal audit found that more than 50 of these cases have exceeded the 10-year statute of limitations on rape. "The evidence that we're talking about represents human lives," Los Angeles Controller Laura Chick tells NOW. "Those are lives stacked up on the shelves waiting for justice." NOW talks with courageous rape survivors and law enforcement experts for insight and answers in this disturbing but important report. Are these women being victimized twice? Next on NOW.
