Banfield Trial: FBI Trust Expert Robin Dreeke Analyzes The Brendan-Juliana Relationship | Who Controlled Whom?

True Crime Today brings you exclusive analysis of the relationship at the heart of the Brendan Banfield murder trial. Retired FBI Special Agent Robin Dreeke — former head of the FBI's Counterintelligence Behavioral Analysis Program and author of books on trust and manipulation — examines who was really in control between Brendan and Juliana Peres Magalhaes.

The prosecution says Brendan manipulated a young au pair into participating in double murder. They claim he expressed his desire to "be rid of" his wife, told Juliana it was "too late to back out," and handed her a gun the morning of the killings. But Juliana isn't a passive victim in this story. She allegedly helped plan and execute the murders, then spent a year telling police the same story Brendan did — before flipping to get a plea deal that sends her home to Brazil.

From jail, Juliana wrote to her mother that she was "heartbroken for doing this to Brendan" and that she loved him. But she wanted to come home.

Dreeke analyzes what that letter reveals about her psychology and her relationship with Brendan. He examines the behavioral markers that separate someone who was genuinely coerced from someone who willingly participated. He explains what causes someone to maintain a lie for a year and what causes them to flip.

The affair started six months before the killings. Juliana was living in the home, caring for Christine's daughter. Dreeke breaks down what that arrangement reveals about power dynamics — and what it takes for two people to form the kind of criminal partnership prosecutors allege.
