Summary
The prosecution's case against Kouri Richins just hit a wall it built itself. On Day 5, Robert Crozier — the alleged original fentanyl source — testified under three immunity deals that he sold Carmen Lauber oxycodone, not fentanyl, and had no fentanyl connection in early 2022. He pointed out errors in his own affidavit, called the language inaccurate, and said his jail interview with detectives felt like them telling him what he'd done rather than asking.
This came hours after Carmen Lauber's second day of cross-examination, where defense attorney Wendy Lewis systematically dismantled her credibility. Lauber admitted her story shifted from three drug purchases to four, that detectives explained events to her during interviews, and that Kouri Richins never asked her for fentanyl. She confirmed Kouri asked for "Michael Jackson stuff" — propofol — an entirely different substance.
Anna Isbell testified she overheard Kouri mention the "Michael Jackson drug" and assumed it was a muscle relaxer. The defense revealed texts showing a detective threatened Isbell with a warrant and a catch pole for her dog to force cooperation. Additional testimony covered cell phone data extraction from four devices and an undercover narcotics officer whose testimony required a camera blackout.
Judge Mrazik denied a mistrial motion filed during the week and sent jurors home after five days that gave the prosecution the science but handed the defense serious ammunition on the question of how fentanyl allegedly reached Kouri Richins. All individuals discussed are presumed innocent until proven guilty.

| 1:12.7 | him to say. Instead, he looked at that jury and told them he never sold fentanyl to Carmen |
