When 30-year-old Alyssa Romine-Olson was found dead at the Riparian Preserve at Water Ranch in Gilbert, Arizona, investigators publicly suggested there was no threat to the community. But behind the scenes, the case file tells a very different story.

In Part 2 of this Crime Junkie investigation, Ashley Flowers and Brit Prawat examine overlooked leads, previously unreported investigative details, and the people police either never fully investigated, or stopped investigating altogether. Because the deeper this case goes, the harder it becomes to believe the original narrative. In this episode, you’ll hear about Alyssa’s connection to The Last Reformation, a controversial religious movement that investigators never publicly explored, the unidentified phone number that contacted Alyssa in the days before her death, the mysterious man seen both at the Riparian Preserve and outside Alyssa’s parents’ home, the registered sex offender whose statements, behavior, and belongings raised serious questions, the evidence that was collected but never fully examined, and why Alyssa’s family believes critical leads were overlooked from the very beginning.

This investigation also explores previously unreleased details from the Gilbert Police case file, the evidence that was destroyed before it could be fully tested, questions surrounding forensic testing, unidentified DNA, and missing personal belongings, the FBI review referenced in the investigative file, and why Alyssa’s family says they still don’t know what investigators truly believe happened. More than ten years later, Alyssa Romine-Olson’s death remains officially undetermined. But after reviewing the investigative records and speaking with Alyssa’s family, Ashley and Brit believe there are still significant questions that deserve answers.
