Q&A

  • What was the prosecution's main argument regarding Corey Richards' motive?

    Prosecutors alleged that Corey Richards was motivated by significant debt and a desire to collect on her husband's life insurance policy. Her affair with Robert Josh Grossman also played a role in establishing her motive.

  • How did investigators connect Henry Tenon to the murder of Jared Brightigan?

    Investigators connected Tenon through a tire found at the crime scene matching one on his truck, which was seen near the scene. A financial trail also linked him to Jared's ex-wife's husband, Mario Fernandez Saldana.

  • Why did Henry Tenon withdraw his guilty plea and refuse to cooperate with prosecutors?

    Tenon's new attorney filed a motion to withdraw his guilty plea, and the judge granted it. This means Tenon will no longer cooperate with prosecutors, significantly impacting the cases against Mario Fernandez Saldana and Shana Gardner.

  • What new evidence was revealed in the Rex Heurman case?

    A new court filing revealed that Heurman, using burner phones, contacted sex workers over 500 times between 2021 and 2023. The defense wants this evidence excluded, arguing it's irrelevant and prejudicial.

  • What was the verdict in the Dale Warner trial?

    The jury found Dale Warner guilty of second-degree murder and tampering with evidence. He was accused of killing his wife, D, and hiding her body in a fertilizer tank.

  • What was the outcome of the sex trafficking trial of the Alexander brothers?

    Orrin, Tal, and Alon Alexander were found guilty on all counts, including rape and sex trafficking. Eleven women testified against them, detailing how the brothers used their status to lure and exploit victims.

  • What is the central question explored in Josh Mankiewicz's podcast, "Trace of Suspicion"?

    The podcast explores the mysterious death of a marine and the subsequent murder charges against his widow. The central question posed is: "What constitutes justice?" as listeners are encouraged to form their own opinions.
