He had it all. Or at least, that’s how it looked from the cheap seats in Foxborough. Aaron Hernandez was 23 years old with a $40 million contract, a beautiful fiancée, a newborn daughter, and a skill set that was basically reshaping how the NFL thought about the tight end position. He was fast. He was mean. He was a matchup nightmare that Tom Brady leaned on whenever the Patriots needed a first down in a tight window.
Then came the morning of June 17, 2013.
Most of us remember exactly where we were when the news broke that a body—later identified as semi-pro player Odin Lloyd—had been found in an industrial park just a mile from Hernandez’s North Attleboro mansion. The fall wasn't just fast; it was a total collapse. Within days, Hernandez went from a Pro Bowl locks to a man in handcuffs, his career over before most players even hit their prime.
But looking back now, the "how" and "why" of Aaron Hernandez have only gotten more complicated. It isn't just a true crime story anymore. It's a medical mystery, a failure of coaching culture, and a cautionary tale about what happens when the human brain is treated like a wrecking ball for twenty years.

The Talent That Nobody Could Stop
We talk about Hernandez now as a "convicted murderer," and rightfully so. But to understand the shock of 2013, you have to remember how good he actually was on the grass. At Bristol Central High School, he wasn't just a star; he was a folk hero. He set state records for receiving yards (1,807) and touchdowns (24) in a single season.
He was a man among boys.
When he got to the University of Florida, things only ramped up. Playing under Urban Meyer and catching passes from Tim Tebow, Hernandez became the centerpiece of an offense that felt futuristic. He won the John Mackey Award in 2009 as the best tight end in the country. He was part of that 2008 National Championship team that people still argue is one of the best college rosters ever assembled.
The Patriots took him in the fourth round of the 2010 draft. Why the fourth? Because even then, the red flags were screaming. There were failed drug tests and whispers about the "wrong crowd" back in Bristol. Still, Bill Belichick thought the "Patriot Way" could fix anyone. For a while, it looked like he was right. Hernandez and Rob Gronkowski became the "Boston TE Party," the first pair of tight ends in league history to each catch at least five touchdowns in back-to-back seasons.
Honestly, he was a unicorn. He could line up as a wideout, a traditional tight end, or even in the backfield as a fullback. Defensive coordinators had zero answers for him.
The Brain That Changed Everything
If the story ended at the trial, it would be tragic but simple. But what happened after Hernandez took his own life in a prison cell in 2017 changed the way we look at contact sports forever.
His family donated his brain to Boston University’s CTE Center. What Dr. Ann McKee found inside was, in her own words, "unprecedented."
Hernandez was 27 when he died. His brain, however, looked like it belonged to a man in his 60s suffering from advanced dementia. He had Stage 3 Chronic Traumatic Encephalopathy (CTE). For context, Stage 4 is the most severe. McKee noted that they had never seen that level of brain damage in someone so young.
The damage wasn't just "there"—it was catastrophic.

The parts of his brain responsible for impulse control, judgment, and emotional regulation were riddled with tau protein deposits. His frontal lobe was essentially falling apart. Does CTE excuse murder? No. But does it explain why a man with everything to lose would engage in paranoid, violent, and impulsive behavior over a "disrespect" at a nightclub?
Science says it probably does.
What Most People Get Wrong About the Trials
There’s a common misconception that Hernandez was a serial killer who got away with most of it. It’s a bit more nuanced than that. He was convicted of the first-degree murder of Odin Lloyd, a sentence that carried life without parole. Lloyd was dating the sister of Hernandez’s fiancée, Shayanna Jenkins. The motive was never entirely clear to the public, but prosecutors painted a picture of a man who felt Lloyd had "betrayed" his trust.
But then there was the 2012 double homicide of Daniel de Abreu and Safiro Furtado.
Hernandez was actually acquitted of those murders just days before his death. The star witness, Alexander Bradley, claimed Hernandez opened fire on the men at a stoplight because one of them accidentally spilled a drink on him earlier that night. The jury didn't buy Bradley's story.
He was a complicated figure, even in court. He was a father who blew kisses to his daughter in the gallery, and a man who supposedly had "Blood" gang ties and a "Glock" tucked in his waistband. He lived in two worlds that were constantly crashing into each other.
The Reality of the "Wrong Crowd"
We often hear that Hernandez just "couldn't leave his past behind." That’s true, but it’s also a bit of a simplification.
The "wrong crowd" wasn't just people he knew from high school; they were people he actively sought out even after signing a $40 million deal. He had a "flop house" in Franklin, Massachusetts, where he kept guns and hung out away from the prying eyes of the Patriots.
He was paranoid. Seriously paranoid.
He thought he was being followed. He thought people were out to get him. He reportedly carried a gun everywhere. If you look at that behavior through the lens of Stage 3 CTE, the paranoia starts to make a terrifying kind of sense. The brain’s "alarm system"—the amygdala—was essentially broken. He was constantly in "fight or flight" mode, and he almost always chose "fight."
Actionable Insights: Lessons from a Tragedy
The story of Aaron Hernandez is a dark chapter in American sports, but it forced several massive shifts in how we handle athletes today.
- CTE Awareness: If you or a loved one plays high-impact sports, understanding the symptoms of repetitive head trauma—mood swings, sudden aggression, and memory loss—is vital. Research from the BU CTE Center shows that it’s not just the "big hits" that matter; it's the thousands of sub-concussive "micro-hits" over a career.
- The Importance of Support Systems: Hernandez lost his father, Dennis, when he was just 16. Many experts believe that was the "anchor" that kept him steady. When that anchor was gone, he drifted toward volatile influences. Modern teams now invest much more heavily in mental health resources and "life coaches" for young players coming from traumatic backgrounds.
- Early Intervention: The University of Florida has faced criticism for years regarding how much they knew about Hernandez's behavior. The lesson for organizations is that "winning" shouldn't come at the cost of ignoring clear signs of psychological distress or criminal leanings.
The best way to respect the memory of the victims in this case—Odin Lloyd, Daniel de Abreu, and Safiro Furtado—is to ensure we aren't just entertained by the violence on the field without acknowledging the physical and mental toll it takes on the people playing the game.
To stay informed on the latest developments in brain health and athlete safety, you can follow the work being done at the Concussion Legacy Foundation or keep up with the Boston University CTE Center’s ongoing research. They continue to use the data from Hernandez's brain to help identify CTE in living patients, something that was impossible when he was still on the field.
