FBI Expert: Is Juliana Magalhães Credible? Plus Blood Evidence Expert Says Banfield Staged the Scene

She lied for over a year. She wrote letters from jail promising to "take the blame" for Brendan Banfield. She told his mother she would "give my life for his." She only flipped after Banfield was arrested, after she was hospitalized from stress, and after his family stopped paying her legal bills. Now Juliana Peres Magalhães is negotiating with Netflix while media producers fund her commissary. In a letter to her mother: "We do deserve something."

And she's the prosecution's entire case. The only person alive who was in that bedroom when Christine Banfield and Joseph Ryan were killed.

Former FBI Special Agent Robin Dreeke—who spent his career reading people and identifying deception as head of the Bureau's Counterintelligence Behavioral Analysis Program—analyzes Juliana's credibility. What does her behavior on the stand tell us? How do you evaluate someone who lied for a year and then flipped? Does the Netflix deal destroy her credibility—or is it irrelevant to whether she's telling the truth? And what does her relationship with Banfield reveal about the psychological dynamics at play?

The prosecution closed with their strongest forensic evidence. Blood stain pattern analyst Iris Dalley Graff testified that Joseph Ryan's body was moved after death and Christine's blood was deliberately placed on Ryan's hands and clothing to frame him. The transfer patterns were "finger-like in shape"—consistent with someone touching him with blood-covered hands. Blood droplets on his forearm suggested dripping from above.

Defense attorney John Carroll moved to dismiss, arguing prosecutors never called a single homicide detective and relied too heavily on a cooperating witness with credibility problems. Judge Penney Azcarate denied the motion. The defense now presents their case. Banfield has pleaded not guilty.
