On 1 August 1966, Charles Whitman, a twenty-five-year-old former Marine, climbed to the top of the clock tower at the University of Texas at Austin and, for more than ninety minutes, fired a rifle at everyone who appeared on campus. He killed fourteen people—fifteen, if an unborn baby is counted—and wounded more than thirty before the police shot him dead. Hours earlier he had murdered his mother and his wife. It was one of the first mass shootings of the modern era, and the documentary Tower reconstructed it decades later. But what made Whitman a key case in biological criminology was not the killing, but what he wrote before and what they found after.
// The theoryThe note, the autopsy and the tumor
Months earlier, Whitman had gone to a university doctor describing overwhelming, violent thoughts that he did not recognize as his own. The night before the massacre he typed a note chilling for its lucidity: it described impulses he did not understand, said he was not himself, and expressly asked that, after his death, an autopsy of his brain be carried out to find out whether there was “something wrong”. It is hard to imagine a more disturbing document: a man about to kill who, with part of his mind, suspects that his own brain is betraying him and begs to have it examined.
They honored his request. The autopsy found a brain tumor—a glioblastoma—which, according to the commission that investigated the case on the orders of the governor of Texas, sat next to the amygdala, the deep structure involved in fear and aggression, possibly compressing it. For the theory of acquired brain damage, Whitman is the touchstone: the case that took neuroscience out of Phineas Gage’s laboratory and placed it at the center of an imaginary courtroom. Because if a tumor was pressing on the region that regulates aggression, the question becomes unavoidable: how much of that massacre was decided by Charles Whitman, and how much by diseased tissue inside his head?
The question with no clean answer
Whitman matters precisely because his case refuses to be resolved. The temptation is to pick a side: either “it was the tumor, he was not responsible”, or “the tumor is an excuse, he was a murderer”. Both answers are too easy. The honest truth is that we can never know for certain: there is no way to separate cleanly how much weight the glioblastoma carried and how much his personal history, his military training, his access to weapons, and his meticulous planning carried—because Whitman planned the killing coldly, something that does not fully fit a simple tumoral outburst. The case teaches us to resist the comfort of a single answer. It permanently installed a reasonable suspicion: that behind some monstrous acts there may be a damaged brain, and that the border between “bad” and “sick” is blurrier than criminal law would like to admit. Whitman did not prove that the tumor made him do it; he proved that we can no longer judge without asking. That doubt, sown by the killer himself when he asked for his autopsy, is his legacy in neurocriminology.
// The subjectThe man who suspected his own head
The most human and most terrible thing about Whitman is that part of him that resisted to the very end. A man wholly lost to violence does not sit down to write asking for an autopsy; he does not seek medical help weeks in advance; he does not leave a record that he knows something is not working. Whitman was, at once, the author of the massacre and the first horrified witness of his own transformation—a man fighting impulses he felt were alien to him and losing the battle. The neuroscientist David Eagleman uses him as a central case in Incognito for exactly that reason: because he shows a divided brain, where the conscious “self” looks on powerless at what other parts of the organ are pushing it to do. None of this makes Whitman innocent. Fourteen people died from his shots, and his criminal guilt, with tumor or without, is a fact. But his case forces us to see responsibility as something that can be partially compromised without disappearing entirely, and to remember that inside a monster there may also be a broken brain asking to be looked at.

// The fault lineNeither the tumor’s alibi, nor forgetting the dead
The fault line with Whitman has two edges. The first is turning the tumor into a total alibi: using the glioblastoma to erase his responsibility entirely and, along the way, to suggest that any violent act could be excused by finding something odd on a scan. That path dissolves all human blame and is as false as it is dangerous. The second edge, the opposite one, is to dismiss neuroscience and treat the autopsy as an irrelevant anecdote: to refuse to admit that a diseased brain could genuinely have altered a man’s capacity to hold himself back. The mature reading holds both things at once—that the tumor may have carried weight and that Whitman remains the author of the killing—and, above all, does not look away from the victims.
Because the subtlest risk in talking about cases like this is that the fascinating enigma of the brain eclipses the dead. The fourteen were shot down from a tower by the decisions of a man who aimed and fired again and again for an hour and a half. His tumor does not bring them back, nor console their families, nor turn the massacre into a mere neurological accident. Understanding Whitman’s brain does not serve to exonerate him: it serves to judge him with more truth, with both him and his victims fitting inside the same verdict. To explain is not to excuse—and in no case does this principle carry more weight than in that of a man who killed fourteen people and asked that his head be opened to find out why.
The case that taught us to ask
Whitman matters because he changed the questions we ask in the face of extreme violence. Before him, a killer was simply evil; after him, forensic neuroscience cannot help asking whether there is a brain substrate—a tumor, a lesion, a deficit—behind certain acts. Not to excuse them, but to understand them and, where appropriate, to qualify the degree of responsibility. His request for an autopsy was, without meaning to be, a foundational act: a killer who gave science the doubt that today forces us to look at the brains of murderers. The lesson is not that tumors kill (almost no one with a glioblastoma commits a massacre), but that the “self” that holds back lives in fragile tissue, and that decent justice must be able to distinguish degrees of capacity to decide. Whitman left us that permanent discomfort: no longer being able to fully condemn without asking, nor to fully excuse for whatever is found. Living in that honest doubt is harder than choosing a side, and that is why it matters.
Three key takeaways
- Charles Whitman killed fourteen people from the tower of the University of Texas in 1966. Beforehand he wrote notes about violent impulses he did not understand and asked for an autopsy of his brain; it found a tumor (glioblastoma) pressing on the amygdala. It is the case that tied neuroscience to crime.
- His case has no clean answer: we can never separate how much weight the tumor carried and how much his history, his training and his cold planning carried. It installed a reasonable suspicion—that behind some monstrous acts there is a damaged brain—without allowing it to become a universal alibi.
- Neither the tumor as a total excuse nor the dismissal of neuroscience: the honest reading holds that the damage may have carried weight and that Whitman remains the author of the killing. Nothing erases the fourteen dead. Explaining the brain serves to judge with more truth, not to exonerate.

Who is Charles Whitman?
Charles Whitman (“el Francotirador de la Torre”) is a villain from Tower, analysed on KRIMINIS through the lens of criminology. Before climbing the tower he wrote a note: "I do not understand myself.
Why does Charles Whitman become a villain?
Charles Whitman killed fourteen people from a tower and asked that his brain be opened to find out why. They found a tumor. The real case that forces us to ask where illness ends and blame begins.
Which criminological theory explains Charles Whitman?
Charles Whitman's case is analysed through Acquired brain injury. On 1 August 1966, Charles Whitman fired from the tower of the University of Texas and killed fourteen people. Beforehand, he had written notes describing violent impulses he did not understand and had asked for an autopsy of his brain. The autopsy found a tumor (glioblastoma) pressing on the amygdala. For the theory of acquired brain damage, Whitman is the foundational case that tied neuroscience to crime—and to the impossible question about the tumor and responsibility.
