Beyond Reasonable Doubt - Season 1 (2017)

The hunt for the so-called Green River Killer, who murdered over 50 women, is the focus. Catching him took an advance in forensic microscopy to indisputably link minute paint particles from the victims' clothes to the killer.

The body of a murdered woman is found in a barrel along with an address book that has been soaked for over 30 years. Spectral imaging is used to recover the information from the address book, which gives the police the break they need.

In 2002, armed with DNA and a license plate from a particularly violent rape case in California, a detective thinks he has an easy case to crack. But neither provides a match. The case goes cold until the groundbreaking Combined DNA Index System finds a hit 5 years.
