How can international cooperation help strengthen forensic science in the Philippines—and ensure that its benefits endure long after training programs conclude?

In this episode of The Forensic Lens Podcast, I reflect on my participation in the Justice Through Science (JTS) Project in Baguio City, an initiative funded by the U.S. Department of State that brought together professionals from across the Philippine justice system for specialized forensic education and training.

Drawing from the JTS experience and international examples of forensic capacity-building, I examine why sustainable progress requires more than workshops and technical assistance. The Philippines needs advanced disciplinary expertise, locally validated forensic methods, stronger research infrastructure, and sustained collaboration among universities, laboratories, law enforcement, and the judiciary.

The ultimate measure of international cooperation is not simply how many professionals are trained, but whether local institutions develop the scientific knowledge, expertise, and independence to sustain and advance forensic science on their own.

Would your beloved cat or dog eat you if you died alone at home? Forensic science suggests that even our most affectionate companions may eventually become scavengers.

In this episode of The Forensic Lens Podcast, I explore how animal scavenging alters human remains after death. Drawing from documented cases and a recent Greek forensic anthropology study, I examine how scavengers consume soft tissues, scatter bones, and leave marks that can be mistaken for trauma. These postmortem changes can complicate death investigations, making it essential to distinguish what caused death from what happened afterward.

Death does not end biological activity. Sometimes, what appears to be evidence of violence is simply evidence that nature continued its work.

Can refrigeration stop decomposition? Not quite.

In this episode of The Forensic Lens Podcast, I examine what happens when a body is placed in cold storage—and why refrigeration can complicate rather than simplify estimates of time since death. Using a recent decomposition study and the case of a woman found inside a refrigerator in Rodriguez, Rizal, I explore how microbial activity, insect development, body temperature, airflow, and prior decomposition can continue to shape the postmortem record even in the cold.

The episode also explains why forensic scientists cannot simply subtract the number of days a body spent refrigerated from the postmortem interval. Refrigeration becomes part of the body’s history, altering some biological clocks while leaving others partly active.

Cold can slow decomposition. It can distort the timeline. But it does not freeze death in place.

What if a crime scene could be sampled not only from the objects inside it, but from the air itself?

In this episode of The Forensic Lens Podcast, I examine a new study on airborne environmental DNA, or eDNA, and its potential use in short-duration crime scenes. Researchers staged fifteen-minute residential burglaries and then tested whether intruders could still be detected genetically after they had left. In some cases, air sampling identified the intruder more successfully than swabbing surfaces they had deliberately touched.

The findings are promising, but they also reveal the interpretive challenges of environmental DNA. Air can contain complex mixtures from residents, visitors, researchers, and older biological material resuspended by movement. Dust, surfaces, and air may therefore tell different stories about occupancy, contact, and recent presence.

Airborne eDNA is not yet ready for routine casework, but it expands a familiar forensic principle. Locard taught us that every contact leaves a trace. Perhaps, increasingly, every presence does too.

How much of a person’s life can survive in a single tooth?

In this episode of The Forensic Lens Podcast, I examine a 2026 study showing how one mandibular premolar can preserve multiple kinds of forensic information. Through radiocarbon analysis, amino-acid racemization, stable isotopes, DNA profiling, and toxicology, a tooth can help estimate birth period and age at death, reveal aspects of childhood diet and geographic background, support genetic identification, and preserve traces of drugs or medications.

The episode also explores a deeper forensic problem: evidence is finite. Many of these techniques are destructive, forcing investigators to decide how much of an irreplaceable specimen should be consumed, which tests should be prioritized, and what should be preserved for future analysis. The real advance is not simply extracting more information—it is learning how to recover multiple independent lines of evidence from less material.

A tooth cannot tell an entire life story. But when the body is badly decomposed, burned, fragmented, or skeletonized, it can remain a remarkably durable biological archive.

Serial killers remain fixtures of popular culture, but the historical numbers tell a different story. In the United States, known serial murder peaked in the late twentieth century and has declined substantially since. So what changed?

In this episode of The Forensic Lens Podcast, I examine the changing ecology of serial murder—from demographic shifts, childhood adversity, lead exposure, mobility, and vulnerable victims to the investigative limitations that once allowed offenders to remain invisible across jurisdictions. I then explore how DNA profiling, investigative genetic genealogy, CCTV, mobile-phone records, digital footprints, and better information sharing have tightened the forensic net around repeat offenders.

But extreme violence has not disappeared. As serial murder became harder to sustain undetected, public mass violence has become increasingly visible in different settings around the world. These are distinct forms of homicide, not interchangeable categories—but their changing prominence raises a larger question: how do social environments, technology, opportunity, and detection shape the forms extreme violence takes?

What happens when a forensic examination does not merely reveal evidence, but may help create it?

In this episode of The Forensic Lens Podcast, I examine the case of Jimmie “Chris” Duncan, who spent 27 years on death row after bite-mark evidence was used to link him to the death of a child. Years later, video footage showed forensic dentist Michael West pressing and scraping a dental mold against the victim’s skin during the postmortem examination—raising the possibility that the procedure altered existing injuries or produced the very marks later presented in court.

The episode explores the crucial difference between developing evidence and inventing it, the weak scientific foundations of bite-mark identification, and the wrongful convictions of Keith Allen Harward and Robert Lee Stinson. Forensic experts are entrusted with extraordinary authority, but that authority must rest on validated methods, transparent documentation, and evidence that existed before the examiner touched it.

When forensic evidence is altered, manufactured, or interpreted through unreliable methods, the consequences do not end with a flawed report. They can take away decades of an innocent person’s life.

What makes evidence trustworthy is not the reputation of the institution presenting it, but whether its source, handling, corrections, and interpretation can be independently examined.

In this episode of The Forensic Lens Podcast, I explore evidence integrity through documentary errors, photocopied records, marked exhibits, and official conclusions. A typo does not automatically invalidate evidence, but neither can every irregularity be casually dismissed. The important question is whether the error affects identity, provenance, custody, chronology, or the ability to reconstruct what happened.

The episode also examines why copies must remain traceable to their originals, why exhibit markings do not establish authenticity, and why interpretation must be separated from direct observation. Institutional authority may introduce a conclusion, but only transparent methods can justify it.

Evidence becomes worthy of trust when every important step remains traceable—from source to copy, mistake to correction, and observation to conclusion.
