In this episode, we examine the case of Taylor Parker and the murder of Reagan Simmons-Hancock through a lens that goes beyond the crime itself and into the psychology of the woman who committed it, the brain that built toward it, and the ten-month fiction she sustained so completely that an entire community believed her.

Rather than focusing solely on what happened inside that house in New Boston, Texas, this episode asks the harder questions: what does lying actually do to a brain over a decade, what happens neurologically when a person deceives not just everyone around them but their own reality-testing systems, and when a defense team put her brain scans on a courtroom screen and argued the organ itself was broken — were they right?

Drawing on research in forensic psychology, the neuroscience of deception, attachment and developmental science, and the literature on factitious behavior and fetal abduction, we explore:

What pseudologia fantastica actually is, how it differs from ordinary deception, and why a lifetime of manufactured illness is a pattern rather than a series of isolated lies.
What the research on the brain's adaptation to dishonesty reveals about escalation — how the amygdala's alarm response weakens with every self-serving lie, and why a conscience is not shattered but slowly turned down.
How childhood instability, unreliable attention, and a permanent loss she never consented to shaped a brain that learned to manufacture crisis rather than grieve it.
Why the confabulation defense collapsed under scrutiny, what frontal lobe dysfunction actually predicts, and why a brain that plans for ten months is not a brain that has lost its brakes.

With a background in public health and behavioral science (graduate training at Johns Hopkins), The Murder Mindset prioritizes education, neuroscience, and systemic analysis over sensationalism, examining not just what happened, but what built the brain that made it possible.

This episode also examines the systemic failure at the center of this case: the physician who knew, with medical certainty, that this pregnancy was impossible — and the privacy law that prevented him from warning anyone. Reagan's family is currently advocating for federal legislation to change it.

Reagan Simmons-Hancock was twenty-one years old. She was a daughter, a sister, a wife, and a mother. She is not the backdrop to someone else's psychology, and this episode belongs to her.
