Zone 7 podcast host, Mac McCollum made sure there tissues available for this panel. They were needed. Her interview with retired US Fish and Wildlife Service Supervisory Special Agent Ed Newcomer didn’t leave a dry eye in the room. These panelists were comfortable with each other and public speaking. The case presented made it clear that these two professionals knew their stuff.
Newcomer gave highlights of his career to enlighten people on why an area like Fish & Wildlife needs special agents and detectives. He investigated illegal trafficking of plants (vital succulents needed for the ecosystem) to a rare butterfly to megafauna like the rhinoceros.

The title of this panel was The Last Rhino and it wasn’t for exaggeration. In April of 2010, Newcomer was on a team investigating the murder of Vietnam’s last Javan rhinoceros (Rhinoceros sondaicus). He was there for a real extinction event. This isn’t Hollywood, but the story deserves to be told.
| How did they know it was the last of its kind? Rhinos are generally fantastic at staying away from humans. They are surveyed and tracked by finding fecal evidence and determining how long it has been there. |
The murder was premeditated. Make no mistake. This was a murder. Inside Cat Tien National Park, this Javan rhino was singled out. The killing occurred during the Tet holiday when no one, not even the rangers, were supposed to be working or even inside that park. Yet, a dead Javan rhino body was found mutilated. Its horn gone. The local law enforcement didn’t save all of the body, only the bones and some toenails. Hearing the story was gut-wrenching. Bearing witness as Newcomer did, had to have been one of the worst sights imaginable.
Many believe that rhino horn is desired by the black market for medicinal myths. The truth is that the completely false belief in medicinal qualities isn’t the primary reason. People covet it. They want horns that are elaborately carved as status symbols. Rhino horn isn’t ivory either. It’s keratin—the same as hair and fingernails.
The rhino did not immediately die. It suffered. According to the official report:
“The examination revealed that the horn was removed after the rhinoceros died. The bullet found lodged in the front left forelimb caused considerable injury and inflammation in the leg which would have resulted in impaired locomotion for the rhinoceros. The alteration of the bones suggests that at least 2 months passed between the time the rhinoceros was shot and the time of death.”
SSA Newcomer and the team (some were from the World Wildlife Fund) examined what they could of the physical evidence and the location where the body was found. All of investigators saw the unmistakable sawing/tool marks on the skull. Yet, the official cause of death was ruled “Natural causes,” which this team knew was bullshit. They also knew that whatever they proved wouldn’t matter to the Vietnam government. They continued and went to the crime scene anyway.
Hiking up and down steep terrain in the jungle would make the average person want to give up. Animals, Newcomer explained, do not hike straight up or down. They zig-zag in order to make the incline safer and more manageable. Newcomer’s team pressed on with their direct route approach until they reached a mind-blowing vantage point of the jungle where they could visualize exactly what happened.
Something was clearly out of place. The trees and jungle foliage were disturbed in a more direct path. Based on the sides of the plants that were broken and leaning, what happened became clear to the investigators. Someone shot the rhino up high. Its injured leg couldn’t support its weight. The densely packed trees and vegetarian cracked as the last Javan rhino of Vietnam tumbled down losing more of its life and strength along the way. Its landing place was busted down bamboo creating a place of hospice where it lingered until dead. The damage of the bamboo formed the shape of the rhino laying across it when discovered. The stalks were not chopped or cut. They were snapped from the force of the rhino’s weight.
Newcomer found the bullet in the skeleton. The bullet was enough to prove that this creature was mercilessly killed. It was the caliber of bullet consistent with an AK-47 rifle. That kind of gun is only found in the military and park rangers. There was another wound discovered on the skeleton that showed this animal had been targeted and shot before. It’s speculation, but likely, that it was a park ranger who shot this rhino.
The only good news is that an NGO discovered a small population of Javan rhinos in a location that will hopefully remain a secret.
If you are curious about seeing the photographic evidence, the linked WWF report listed in my resources includes the photos and specifics of the investigation.
I was able to get in the last question before the panel closed. This time, it wasn’t a question. I was excited to have a chance at the mic in a room full of animal lovers. I told the panelists and audience about how I’ve been able to be someone outside the worlds of science and law enforcement, yet make a difference. Not even a humblebrag. Straight up brag. Because of the trailcams and adventures with Gus and Oliver, I’ve gotten photographic and physical evidence of our New Jersey ecosystem. I use Merlin ID app and iNaturalist app to confirm my sightings of least concern animals (like the white-tailed deer) to the endangered in NJ species like bobcats. If you’re familiar with my weekly cat detective stories, you’ve seen my collection of bones, photos of tracks, blurry photos of animals, photos of feces, opening owl pellets, and more. I was contacted by the NJDEP about my bobcat content. They were thrilled by my contributions on iNaturalist and urged me to use their online reporting system. I got to have a moment of pride when I told the contact that I’ve been uploading my wildlife reports for so many years, they go back to the old emailing of PDF system. Now it’s quick and easy using ArcGIS.
