Days before his suicide in 2017, former New England Patriot Aaron Hernandez sounded triumphant in phone calls from prison, buoyed by his recent acquittal in his trial for double murder that had him imagining a life outside bars, cleared of all criminal charges.
In newly released recordings of his phone calls, Hernandez was so bullish after his courtroom victory on April 14, that he entertained speculation about returning to football from his fellow inmates, who he said asked him, “Who you gonna play for?”
The 27-year-old was a celebrity inmate: Once a star tight end for the Patriots with a $40 million contract, Hernandez proved also to be a violent killer. Though he was acquitted in the double murder of two men in Boston who he seemed to barely know, a jury in 2015 had already convicted him of killing a friend for reasons that were never clear.
In his last 36 hours, Hernandez in phone calls expressed optimism that he could still successfully appeal that guilty verdict, freeing him from his life-without-parole sentence.
“I’m great, man. One step closer,” Hernandez told a friend, according to a redacted recording of their phone conversation that state prison officials released after a lengthy public records fight. There is, he added, “light at the end of the tunnel.”
Within hours, Hernandez would be dead.
Hernandez’s suicide on April 19, 2017, left behind more than a cell adorned with biblical references and rambling letters. His family and friends continue to wrestle with the contradiction of Hernandez’s final days: That a seemingly jubilant man who was planning visits with his daughter and her mother could suddenly kill himself.
The questions have fueled speculation about why Hernandez took his own life. Did an illicit drug he smoked in prison send him spiraling? Or was his death the byproduct of a head so addled by repeated blows that one medical expert said he had some of the worst brain damage she had seen in a football player?
Did he suffer from well-concealed depression? Or did the suggestion on a radio talk show that he was gay, just days before his suicide, push him past the brink?
The newly released phone calls — nine in all spanning his final two days — also offer fresh insight into Hernandez’s life and reflections behind bars.
In the mystery about what prompted Hernandez’s death, experts warn that suicide can rarely be distilled to a singular trigger.
“Most of the time, suicide is the result of a combination of a lot of factors,” said Eileen Davis, director of Call2Talk, a statewide suicide prevention hot line. “It’s almost like a perfect storm in your head. It might be something specific that brings you to that extreme act, but it is something that has probably been” brewing.
She said it’s also not unusual for someone to seem hopeful before a suicide. “Oftentimes, individuals that do take their own lives do sound more upbeat and positive in the hours, days, weeks prior,” Davis said.
The recordings of the calls Hernandez made before he hanged himself did not point to a cause.
The phone calls do provide some clues as Hernandez made fleeting references to forces that may have hastened his death.
The recordings were obtained by WBUR and The Boston Globe after a public records battle with the state Department of Correction that began as a part of the Globe Spotlight Team’s 2018 series and podcast “Gladiator: Aaron Hernandez and Football Inc.,” produced in partnership with Wondery.
In one call, Hernandez described watching a fellow inmate “twitching and having a seizure” and vomiting blood after taking that “artificial shit” — which sounded like a reference to the drug K2 that he himself had allegedly used. Often referred to as synthetic marijuana, the drug is sprayed onto paper or other material then smoked. Hernandez said the inmate overdosed “right in front of my cell.”
You remember that, remember that artificial shit down in college? [Expletive] hit that shit and started tweaking, fam. [Expletive] standing in front of my cell. I’m like, we got to lock in. You got to go to your cell, man. Yo, he just starts tweaking, like twitching and having a seizure-type shit. I’m like, I’m like yo close my door. The [expletive] ODs right in front of my cell, puking blood. They trying to grab him. Tweaking like tweaking like just shaking, like he doesn’t know what’s going on. Like, yo, this shit was crazy, fam. Everybody locked in and this [expletive] is just sitting there shaking, holding on to the top tier. I’m like, yo this [expletive] is buggin’.
Prison officials said they had no record of the incident Hernandez described. When Hernandez died, K2 was so rampant at Souza-Baranowski Correctional Center that outside the prison on a tree hung a sign with a skull and crossbones that warned “K2 is poison.”
The Spotlight Team reported in 2018 that prison officials concealed records after Hernandez’s suicide showing that another inmate reported Hernandez had been smoking the drug for two days before he died and “wasn’t in the right frame of mind.”
A postmortem toxicology screen of Hernandez’s blood was negative for K2 and other illicit substances, but state officials have declined to detail the thoroughness of the test. The drug can often be difficult to detect.
K2 is a synthetic version of the psychoactive ingredient in marijuana, but it can be far more dangerous, according to Dr. Nora Volkow, director of the National Institute on Drug Abuse.
“These are synthetic cannabinoids that produce very, very severe psychosis,” Volkow said. “And those can be terrifying experiences,” which lead some people “to actually want to kill themselves.”
While a typical high might last a few hours, the psychosis can last for days. Volkow compared K2 to “Russian roulette” because users don’t know what chemical they are consuming.
A person who has suffered brain trauma is especially vulnerable to the dangers of the drug, Volkow said.
In another call, Hernandez mentioned the brain trauma endured while playing football. The context was difficult to determine because, in the recordings, prison officials erased the voice of the person Hernandez was speaking to. It sounded like Hernandez was on the phone with another football player discussing a concussion-related lawsuit.
Hernandez referred to that “concussion shit,” and vowed to “talk to my lawyers about it” because “it will benefit us all.”
Get me the information so I can get on that ASAP for all of us with that concussion shit. And tell everybody I send my love, man. I hope the best for you, man. I hope everything keeps going well for you, man. Tell me what I got to do or whether I got to talk to my lawyers. Because I’ll even talk to my lawyers about it, too, you know? And then, see what they could do on that end, too, you know, because it’ll benefit us all. Everything I -- all the information I need to do and I’ll bring it to my lawyer’s attention ASAP.
After his death, Hernandez’s brain showed that he had one of the worst cases of chronic traumatic encephalopathy, or CTE, ever seen in someone so young. The progressive degenerative condition is believed to be caused by repeated blows to the head.
While no direct link has been made between CTE and suicide, it is the most common cause of death for people under age 30 who, like Hernandez, had donated their brains to the Boston University CTE Center, according to the center’s director, Dr. Ann McKee.
The trauma in Hernandez’s brain still stands out to McKee, who described damage so considerable to his frontal cortex that she determined he had stage three CTE on a scale of four.
“That’s the kind we usually see in people that are in their 60s, 70s, and 80s,” said McKee, a neuropathologist.
People suffering from CTE do exhibit “impulsivity and very sudden changes in behavior” and increased “suicidal ideation,” McKee said. “But it’s very hard to just blame or just point the direct link to CTE” because so many factors contribute to suicide.
The prison calls are also notable for what was not mentioned: Hernandez gave no indication on the calls whether he learned that, in the days before his death, a radio talk show in Boston had been making jokes about his sexuality, an issue he kept secret for years.
Hernandez’s mother declined an interview request. But in an e-mail to the Globe, Terri Hernandez referred to the talk show and its jokes about her son’s sexuality as a potential reason for his suicide. She added, however, “We will never know.”
After Hernandez died, one of his former high school football teammates told the Globe that he and Hernandez had a sexual relationship while teenagers. Hernandez also told his mother he was gay during a visit in prison.
As is common with those who were close to suicide victims, Hernandez’s friends still struggle to understand why. In November 2022, five retired professional football players discussed Hernandez on a podcast, offering the most extensive comments on his death by those who knew him from the gridiron.
The players, who did not respond to the Globe’s requests for comment, referred to Hernandez as “Chico,” his locker room nickname. As it happened, at least two of the retired players said on the show they had spoken to Hernandez by phone hours before he killed himself.
“In that conversation he was the Chico I remember … happy, fun, just full of life, full of energy,” said Fred Taylor, a retired Jacksonville Jaguars and New England Patriots running back who has been involved in concussion litigation and is now a co-host of the The Pivot podcast. “When they say he allegedly committed suicide, it was hard for me to believe.”
Hernandez’s close friend retired NFL star Maurkice Pouncey of the Pittsburgh Steelers shared Taylor’s disbelief and said that his initial reaction was that “someone killed him.”
Maurkice’s twin brother, Mike Pouncey, said that Hernandez “called everyone that mattered to him” on his last day and that “we all got that same impression” that he sounded happy.
“When we heard the news the next day, ‘I’m like, Bro there’s no way. How? How?’ I got off the phone [with Hernandez] and we were laughing, everything was cool,” said Mike Pouncey, who was also an NFL star for the Miami Dolphins. “There was no indication leading up to that.”
“That’s why,” Mike Pouncey concluded in his remarks on the podcast, “you don’t know people when they’re behind closed doors.”
It took state correction officials five years to release Hernandez’s final calls and ultimately they provided only a small selection of his phone calls from prison. Citing privacy concerns, the agency also excluded the voices of the people to whom Hernandez was speaking. Earlier this month, responding to an appeal, the secretary of state’s office questioned the necessity of the redactions and ordered a review of the full recordings.
By contrast, both the Bristol and Suffolk county jails released the complete recordings of Hernandez’s phone calls several years ago requested by the Globe, disclosing the full conversations he had with family and friends.
A number of those jail calls were featured in the six-part Gladiator podcast. The Spotlight Team found that Hernandez, despite a difficult childhood with an abusive and tyrannical father, gained prominence as a singular football talent. But behind his on-field accolades, Hernandez was a chronic marijuana smoker and risk taker, with a propensity for guns and violence, who struggled with his sexuality in the hypermasculine world of big time football.
Raised in Bristol, Conn., Hernandez won a national championship with the University of Florida Gators before being drafted by the Patriots at age 20. After three seasons in the NFL, Hernandez was marched out of his home in handcuffs, charged with and ultimately convicted of the 2013 murder of his friend, Odin Lloyd, in North Attleboro. The motive was never clear in the killing, which occurred near Hernandez’s home after a night out in Boston.
Hernandez would be accused of murdering two others — Safiro Furtado and Daniel de Abreu — in a drive-by shooting in Boston’s South End in 2012. Hernandez and the men were in the same nightclub before they were gunned down in their car. A jury acquitted Hernandez of those charges April 14, 2017.
Five days later, a guard found Hernandez hanging from a bedsheet tied around bars of a window in his cell in Souza-Baranowski in Central Massachusetts. He left letters and religious writings on the walls. A Bible reference, John 3:16, was written on his forehead in red. The medical examiner ruled his death a suicide.
Prison officials launched an investigation that found no evidence of foul play although a prison guard neglected his duties, skipping his 2 a.m. round to check on Hernandez and other inmates. That was the last hourly round before Hernandez was found dead.
Attorney George Leontire, who represented Hernandez, said in a recent interview the suicide did not make sense because Hernandez sounded so overall upbeat before his death.
“We were shocked,” Leontire said.
On one call, Hernandez said his acquittal felt like “the whole world just came off my back.” In his final two days, Hernandez called friends he had been unable to talk to during his trial. He joked about gaining weight, mentioned resuming his workout regime, and looked ahead to his next legal battle.
“I’m going to fight to the end to get myself home,” he told a friend. “When I sit down, it’s game time, you know.”
I’m good, you know. I’m great, man. One step closer. I’m going to fight to the end to get myself home. When I touch down, it’s game time, you know? Everything gonna work out perfect, man. I just got to have faith, man. That’s all you got, you know? Word. When everything is flipped around, fam, and my innocence is proven -- I already can see [expletive] being nice to me now. Like even these cops have changed how they talk to me, because they see the light at the end of the tunnel.
The calls also show Hernandez had developed an intense relationship with a young inmate who was an aspiring rapper. The man had recently been released from prison and was living in a dangerous neighborhood. Talking to the rapper by phone, Hernandez spoke like a mentor, urging him to swallow his pride and steer clear of violence.
“Just make sure you keep your head up. You’re bigger than that,” Hernandez said. He added, “All I’m saying is, take a deep breath. Don’t react off emotion.”
As he doled out advice, Hernandez reflected on his own choices. Hernandez talked about the people he’d surrounded himself with when he was a football star and he urged the young rapper to make better decisions. The Globe has been unable to identify him.
I was searching for love so I gave my love and loyalty to everybody to never get it in return. But where does that get you? I’m not giving my love to all these people that don’t deserve it, and you shouldn’t either, fam. You’ve got a special type of love. That’s why I understand. Because your love and loyalty is so real. That’s why I stopped all that hate shit. You got a special love and loyalty. If you’re going to give it to someone, make somebody earn that shit. Or else nobody’s going to be there for you, fam.
In his final phone call, it was clear that Hernandez had reached his fiancée, Shayanna Jenkins-Hernandez, who declined to comment for this story. When Hernandez called, Jenkins-Hernandez was shopping with their daughter at Target.
Hernandez sounded both silly and affectionate, at one point telling his daughter she was “the most beautiful girl in the world.” He talked about visits in the coming days with Jenkins-Hernandez. He urged her to set up some one-on-one time between them, suggesting she occasionally leave their daughter with her mother when she made the trek to prison to see him.
Then suddenly, for a reason not clear on the recording, Jenkins-Hernandez had to hang up and the call was cut short.
“Go,” Hernandez said as he made kissing noises to his daughter and her mother. " Love you guys.”
The excerpts of Hernandez’s prison calls have been edited for clarity and profane language.
