In this episode of Pretty Lies & Alibis, we break down Day 1 of the Kouri Richins evidentiary hearing and the key expert testimony battles unfolding ahead of her upcoming trial.

The defense sought to block three of the state’s expert witnesses, focusing heavily on the controversial “Pathway to Violence” model. Defense expert Dr. Fox testified that the model is not scientifically reliable, lacks peer-reviewed validation, has no known error rate, and cannot be used to predict individual acts of violence — arguing that its use amounts to profiling rather than science under Utah Rule of Evidence 702.

The state countered with testimony from Dr. Ammon, who described the model as one of several tools used retrospectively in targeted violence prevention. The judge ultimately issued a partial ruling, limiting how the model may be used at trial.

We also cover:
The judge’s decision allowing a handwriting expert to testify regarding alleged forgery

Why testimony from Dr. Sherry Veneno was ruled not currently relevant — but could be revisited

Why Day 2 of the hearing will not be livestreamed due to sealed evidence
