August, 2013. A grisly discovery is made in the desert outskirts of Phoenix. The partial remains of a young woman are found, unearthed by a monsoon. Days turn to weeks, weeks to months…months to years. And still her case remains unsolved. Her name? Adrienne Salinas.

In this 6-episode docu-series, award-winning investigative reporter, Morgan Loew, takes a new look at her murder, following a trail of information that twists and turns from Phoenix to New Mexico to Washington. Where will it all lead and will Adrienne’s story remain…Unresolved?

Two women. Two crimes. One night.

Is the murder of a young woman, whose body is found in a Tempe street, connected to the disappearance of college student, Adrienne Salinas?

Morgan Loew investigates both cases, just three miles apart, and finds the answer that puts him on an even darker path.

After 19-year-old, Adrienne Salinas, seemingly vanishes from a Tempe street, two months pass and still no leads as to her whereabouts. But on the outskirts of Phoenix, a desert secret reveals itself to police.

Investigative reporter, Morgan Loew, delves deeper into Adrienne’s disappearance after torrential rains unearth the gruesome discovery, and it takes him back to a night when almost everyone is called into question.

As the mystery deepens into the disappearance and death of 19-year-old, Adrienne Salinas, police begin to sort through a growing list of potential persons-of-interest. From a boyfriend to partygoers to a cab driver, detectives realize Adrienne’s vanishing could lead down several winding paths, each darker than the next.

A crime reporter remembers a pair of gruesome murders that took place decades ago. The man charged in the case has an affinity for zombies. And police believe there could be more victims. Could the so-called Zombie Hunter have come across Adrienne Salinas before she vanished?

The search for answers in Adrienne Salinas’s death leads to the Pacific Northwest, where the accused serial killer known as the Zombie Hunter lived in the late 1990s and early 2000s. He’s been linked to attacks against young women in the town of Everett, Washington. Those attacks bear some similarities to the Phoenix Canal Murders. They also share something in common with Salinas’s case.

Investigators follow a new lead to a jail in southern Arizona. And their efforts to isolate cell phone signals at the scene of Adrienne’s disappearance and the location where her remains were found hit a dead end. Adrienne’s family and friends make a plea for anyone with information about the case to come forward.
