44: Damn Damning DNA That Will Destroy Rex Heuermann

In a recent episode of the acclaimed podcast "Hidden Killers", host Tony Brueski had a riveting conversation with Forensic Psychologist Kate Wallinga. The focal point of their discussion was the ongoing Rex Heuerman case, which has witnessed yet another twist. As per recent developments, Heuerman's DNA is set for another round of testing.

Last week, the case gained attention when the defense argued that there wasn't sufficient probable cause to mandate a DNA test. Their contention was quickly dismissed by a judge, stating, “The court finds contrary to the defendant's contentions. There is probable cause to believe that the defendant committed the crimes charged, and therefore a basis to compel for the buccal swab."

This buccal swab, a procedure where cells are collected from the inside of a person's cheek, is pivotal. The DNA obtained will be compared with the mitochondrial DNA sample that was retrieved from a strand of hair. This hair was found on some of the victims, specifically on the burlap sacks that were used to cover their heads. Another compelling piece of evidence was a pizza crust found outside of Heuerman's office, which eventually led to his arrest.

Brueski expressed astonishment at the defense's argument, considering the substantial evidence already available. He posed a significant question: "I was amazed that anybody could be making the argument if this doesn't reach the level of probable cause, considering everything they pulled out of his house and all the other pieces of evidence that seem to link him to these crimes. What possibly does?"

Wallinga, with her forensic expertise, provided a comprehensive explanation. "The police's job is to find you guilty. Like cops, that's what they do. Their job is to find ways that you are getting in trouble and hold you accountable," she began. She clarified the roles of the police and defense attorneys, stating that while police aim to find guilt, the defense's job is to ensure that every step taken by the police is legitimate and above board. The defense's duty is to hold the police accountable.

She further delved into the intricacies of DNA-related cases, shedding light on the nuances involved. "It's really common in DNA cases like this where they find the mitochondrial DNA in the trash, for instance, because trash becomes public property. And then after that, you have to get a search warrant for a cheek swab," Wallinga explained.

This suggests that while the process may seem straightforward to the public, the legal intricacies and procedures involved can be complex. Both the police and the defense have their specific roles and responsibilities, and ensuring that each party adheres to their duties is crucial for the integrity of the justice system.

As the Rex Heuerman case progresses, it becomes evident that DNA testing and its legal stipulations play an indispensable role. Both Brueski and Wallinga’s conversation underscores the importance of understanding the legal procedures, ensuring that justice is not only done but is also seen to be done. As new evidence unfolds and the legal debate continues, listeners and followers of the case await the next chapter in this intriguing saga.
