Why Did Aaron Hernandez Kill Odin Lloyd? Motives, CTE, Childhood

Why did Aaron Hernandez kill Odin Lloyd? Prosecutors argued at trial that the former New England Patriots tight end murdered Lloyd on June 17, 2013, for two overlapping reasons: Hernandez felt disrespected by Lloyd at a Boston nightclub two days earlier, and Lloyd knew too much about Hernandez’s hidden life. Reporting after Hernandez’s 2017 suicide added more possible layers — concealed bisexuality, severe brain disease, childhood abuse, and a documented pattern of paranoia-driven violence. No single clean motive was ever established, and the Netflix documentary’s producers concluded flatly that “there remains no known motive” in the traditional sense.¹

The Nightclub Slight

On the night of June 14–15, 2013, Hernandez went to the Boston club Rumor with Lloyd and Hernandez’s barber. Security footage showed Hernandez spending much of the night alone, agitated, waving his arms.² Lead prosecutor William McCauley told the jury that Hernandez became angry because Lloyd was talking to other people at the club rather than giving Hernandez his full attention. To someone with Hernandez’s “arrogance,” McCauley argued, that slight was enough to send him back to his car for a gun.³ A valet at a nearby hotel testified he saw Hernandez tuck a firearm into his waistband that night.⁴

The theory had weaknesses. Defense attorneys told the jury the club incident “was not a problem,” and the prosecution’s key nightclub witness struggled under cross-examination to explain what specifically triggered Hernandez’s anger.⁵ Investigators who worked the case described the killing as paranoid and acknowledged the triggering events were, by any rational measure, trivial — of a piece with the spilled drink that prosecutors said motivated a separate double murder they attributed to Hernandez the year before.²

What Lloyd Knew

The second prong of the prosecution’s case was that Lloyd simply knew too much. Hernandez kept a secret apartment in Franklin, Massachusetts — a $1,200-a-month unit where police later found five boxes of .45-caliber ammunition matching the shells recovered from Lloyd’s body, along with clothing that linked Hernandez to the night of the murder and to the nightclub outing two days before.⁶ Lloyd was aware of the apartment, certain associates, and the guns. “He knew too much about Hernandez,” McCauley told the jury.³ Some reporting indicated Lloyd may also have had knowledge of Hernandez’s involvement in a 2012 double homicide in Boston.

The two men were connected through their partners. Lloyd was dating Shaneah Jenkins, whose sister Shayanna was engaged to Hernandez. Friends called them “unlikely associates”: Hernandez had a five-year, $40 million Patriots contract, while Lloyd was a 27-year-old landscaper who played semi-pro football and lived with his mother.⁷ McCauley rejected the defense’s portrayal of them as friends, telling jurors Lloyd was essentially Hernandez’s marijuana supplier who “rolled blunts” for him.³

The Sexuality Theory

After Hernandez’s death, journalist Michele McPhee reported in Newsweek that law enforcement had investigated a motive that “never made headlines”: that Lloyd knew Hernandez was bisexual and that Hernandez feared Lloyd would tell his girlfriend Shaneah, who would in turn tell her sister, Hernandez’s fiancée.⁸

According to McPhee’s reporting, co-defendant Ernest Wallace told detectives that Lloyd had called Hernandez a “schmoocher,” which Hernandez and his associates interpreted as a gay slur. Wallace was later recorded during a jailhouse visit saying he would not have helped dispose of the murder weapon had he known Hernandez was a “limp wrist.”⁸ McPhee also reported that shortly before his arrest, Hernandez moved a large sum into an account designated for a male high school classmate with whom he allegedly had an intimate relationship, more than he set aside for his fiancée or daughter.⁹

That classmate, Dennis SanSoucie, later confirmed publicly that he and Hernandez had an on-and-off sexual relationship from seventh grade through their junior year of high school. SanSoucie told Netflix’s 2020 documentary they hid the relationship because they feared their “homophobic” fathers would disown them.¹⁰

The sexuality theory was never introduced at trial and remains contested. Hernandez’s attorney Jose Baez called the claims “false” and described them as “malicious leaks.” The Boston Globe reported it was unable to verify the rumors as fact, and media-ethics expert Kelly McBride characterized McPhee’s Newsweek reporting as “careless.”¹¹

The Brain Damage Question

After Hernandez’s suicide at age 27, researchers at Boston University examined his brain and found Stage 3 chronic traumatic encephalopathy, the most severe case of CTE ever documented in a person his age. Dr. Ann McKee, director of BU’s CTE Center, said the damage was “classic CTE” and included significant deterioration of the frontal lobes, which govern decision-making, impulse control, and social behavior, along with a shrunken fornix and damage to the amygdala.¹² McKee said the damage had taken “years to develop” and would have “significantly affected his decision-making, judgment and cognition.”¹³

McKee stopped short of drawing a direct line between the pathology and any specific act. Other experts noted there is no proof CTE-related damage causes violent behavior, and substance abuse and other conditions can produce similar symptoms.¹⁴ The diagnosis did not answer the question of motive, but it offered a medical frame for why a 23-year-old millionaire would kill an unarmed acquaintance over a perceived slight.

A Pattern, Not an Incident

Lloyd’s murder did not happen in isolation, and the pattern around it is part of any honest answer to the question of why. Hernandez was separately charged with the July 2012 drive-by killings of Daniel de Abreu and Safiro Furtado outside a Boston nightclub, which prosecutors said were triggered by a spilled drink. Alexander Bradley, a former close friend, testified he watched Hernandez fire from an SUV at the victims’ car.¹⁵ Hernandez was also charged with shooting Bradley in the face in a Florida industrial park in February 2013 to keep him quiet about the double homicide. Bradley survived but lost his right eye.¹⁶

A jury acquitted Hernandez of both murders and the witness-intimidation charge in April 2017, though it convicted him of unlawful firearm possession.¹⁷ The acquittal did not disturb his life sentence for killing Lloyd. What the earlier cases do show, regardless of the verdicts, is that the same investigators who worked Lloyd’s case saw small triggers producing lethal reactions more than once.

Childhood and What Shaped Him

Hernandez grew up in Bristol, Connecticut, under the strict and often violent hand of his father, Dennis Hernandez, a former high school sports star who subjected Aaron and his older brother Jonathan to severe beatings. Dennis enforced rigid ideas about masculinity, reportedly prohibiting Aaron from cheerleading. He died in 2006 from an infection after hernia surgery, a loss author James Patterson and others have called a turning point in Hernandez’s life.¹⁸

As an adult, Hernandez disclosed that he had been “molested fairly intensely” as a child, an experience his attorney George Leontire said Hernandez believed contributed to his struggle with his sexual identity.¹⁸ Prison records listed him as a member of the Bloods, and while awaiting trial he was disciplined repeatedly for threatening to kill a corrections officer, aggravated assault, possessing a homemade weapon, and possessing gang paraphernalia.¹⁹

Why No Single Answer Exists

The executive producer of Netflix’s documentary on Hernandez described the killing as a “perfect cocktail of circumstances”: family trauma, unresolved sexuality, CTE, substance abuse, paranoia about being exposed, and an infatuation with guns and violence all converging on a single night.¹ The producers concluded that no known motive exists in the traditional sense. There was no clear dispute over money, territory, or revenge that would explain why Hernandez lured an unarmed man he had treated as a friend into a car at 2:30 a.m. and killed him in an industrial park less than a mile from his own front door.

What the Fall River jury found in 2015 was that Hernandez committed first-degree murder, a verdict that carried a mandatory life sentence without parole.²⁰ What prosecutors proved was not why Hernandez killed Odin Lloyd, but that he did.
