Anderson lost one of his cattle in June 2021. As he says inUnsolved Mysteriesvolume 5, episode 3, the heifer had been acting strange the day before she died. He later discovered the animal’s face had been skinned back, her tongue was removed, and she had a cut behind her shoulder with her hide pulled back. Anderson didn’t notice any tracks, blood, or signs of struggle on the ground around the heifer’s body. He calledthe police, who performed an investigation and determined that a bear killed the cattle,which Anderson found hard to believe.
As for Carter’s experience with the phenomenon, the rancher found his cow dead in August 2020. He explains inthe bizarreUnsolved Mysteriesepisodethat the animal’s upper lip was cut off, her tongue was missing, and her intestines were falling out between her hind legs. Two years later,one of Carter’s bulls had been mutilated.Similar to Anderson’s heffer, there were no tracks or blood surrounding the bull’s body (despite there being snow on the ground). Unfortunately, neither Carter nor Anderson have learned exactly what happened to their animals.
Mysterious Cattle Mutilations Have Been An Unsolved Phenomenon Since Before The 1970s
The Question Of Who Or What Is Performing The Cattle Mutilations Remains Unsolved
Mat Carter and M.T. Anderson are far from being the only ranchers who have experienced the mysterious cattle mutilations. For more than five decades, Oregon ranchers (and ones across the country) have found their animals mutilated, and the circumstances surrounding their deaths are always unusual.No one has been able to figure out how these cattle are dyingand who or what is behind these awful crimes. Unfortunately, like the vast majority ofthe cases discussed inUnsolved Mysteries, the cattle mutilations in Oregon and elsewhere remain unsolved.
Everything Unsolved Mysteries Leaves Out About The Jack Wheeler Murder Case
Jack Wheeler’s death is the focus on the Unsolved Mysteries episode “Washington Insider Murder,” but the series leaves out some key information.
According toNetflix by Tudum, even Terry Dunn Meurer, the creator and executive producer ofUnsolved Mysteries, was puzzled by the cattle mutilation case.Unsolved Mysterieshas covered numerous casesover the course of its 37-year history, so, to say"Mysterious Mutilatios" ranks among the documentary TV show’s top most mystifying mysteriesis an impressive statement. Meurer explained:
“This is probably the most mysterious mystery we’ve ever profiled. There are no suspects and no definitive theories about why cattle have been murdered and mutilated in multiple states, across decades. It’s crazy to say this, but UFOs almost seem like the most likely theory.”
No Blood Has Been Found With Unsolved Mysteries' Cattle Mutilation Cases
One Of The Strangest Parts Of The Mutilations Is The Absence Of Blood
Ranchers finding their cattle mutilated is quite puzzling and horrifying all on its own, but the evidence (or lack thereof) surrounding the animals' deaths makes the phenomenon even more confusing.There is never any blood on the ground surrounding the corpses,despite the brutal nature of their deaths. One would think that when a cow is cut with surgical-style incisions, has their tongue removed, and/or their organs taken out, there would be blood everywhere.
More than a thousand cattle mutilation cases have been reported across the United States and Canada, and no one has been able to solve them.
Nevertheless, the lack of blood at each scene is probably themost disturbing aspect of theUnsolved Mysteriescase. While seeing the blood would be horrific, it would just make sense given the cattle’s deaths. So,since there’s no blood, the phenomenon is even more eerie.Plus, there are never any tracks or evidence around the bodies, indicating that anyone had ever been there. More than a thousand cattle mutilation cases have been reported across the United States and Canada, and no one has been able to solve them. However, many people have theories.
What Theories Have Been Posed To Explain The Mysterious Cattle Mutilations
UFOs Have Been Blamed
Of course, when one can’t point to scientific reasoning behind strange cases, UFOs and aliens are looked at for answers, and that is what has happened with the cattle mutilations that have plagued ranchers for decades. As mentioned above,Unsolved Mysteriescreator and executive producer Terry Dunn Meurerbelieves thatUFOs are the best theory for what has been happening to these cattle.Unfortunately, there is no evidence to prove this theory other than the fact that there is a lack of evidence.
Unsolved Mysteriesvolume 5 serves as the second part of season 17, following the release of volume 4 on August 07, 2025. Volume 4 consists of five episodes, ranging from the Jack the Ripper case to the Mothman.
However,some blame cults for the cattle mutilations.Whatever the case, ranchers like Mat Carter and M.T. Anderson are determined to figure out the truth behind this strange phenomenon. Perhaps they will never get answers, or they will crack open the case one day. Until then, thisUnsolved Mysteriesvolume 5 case remains unsolved.
