The Monster He Wanted to Become

In this episode of Pushing Up Lilies, I’m covering the heartbreaking case of Rachel Castillo, a young mother whose disappearance in Southern California led investigators to a devastating discovery, and ultimately, the conviction of her estranged husband, Zarbab Ali. Rachel vanished during what should have been a routine custody exchange involving her children. But almost immediately, investigators began uncovering signs that something was terribly wrong. What followed was an intense investigation involving surveillance footage, blood evidence, digital tracking, and a search that ended with Rachel’s body being found buried in a remote area. As a forensic death investigator, I walk through how cases like this begin to unfold behind the scenes, how small pieces of evidence start forming a timeline, how investigators interpret behavioral patterns, and how critical those early investigative decisions become when someone suddenly disappears under suspicious circumstances. This episode contains discussion of domestic violence, homicide, and burial concealment.  Listener discretion is advised.
