For more than a decade and a half, Eileen and Keen Umbehr have focused their efforts on the case of Dana Chandler, who was convicted of a double murder. The couple, described as true-crime enthusiasts, embarked on what has been characterized as an obsessive mission to prove Chandler’s innocence. Their journey, which involved years of independent research and advocacy, has now been documented in a three-part HBO series.

The Umbehrs’ involvement began after they became interested in the details of the prosecution against Chandler. Over the course of 15 years, they sought to uncover evidence they believed was overlooked or mishandled during the legal proceedings. The case, which centers on the double homicide, remains a point of intense focus for the couple, who have treated the investigation as an all-consuming project.

While the documentary highlights the couple's dedication, it also explores the complexities that arose as they delved deeper into the legal system. The Umbehrs’ efforts represent a growing trend of private citizens taking on the roles of amateur investigators in high-profile criminal cases. The HBO series examines both the couple’s personal commitment to the cause and the broader implications of their attempt to overturn a murder conviction. As of now, the couple continues to advocate for their perspective on the case, maintaining that the original prosecution was flawed.
