David Cox was among ten Marines who hazed Private William Alvarado at Guantanamo Bay in 1986; Alvarado survived. Cox was convicted of simple assault and received an honorable discharge in 1989. He disappeared in January 1994 and his body was found in April 1994 with multiple gunshot wounds in what investigators described as an execution-style killing. The motive and perpetrator remain unknown and the investigation is still open.

David Cox maintained he had done nothing criminal, but his name became linked to a notorious 1986 hazing at Naval Station Guantanamo Bay and, years later, to an unsolved murder. The incident inspired Aaron Sorkin’s A Few Good Men, though the film dramatizes key facts: the real case involved a surviving victim and disputed command responsibility.

What Happened at Guantanamo Bay (1986)
In 1986, Private 1st Class William Alvarado reported alleged fence-line shootings of Cuban soldiers by members of his unit. In retaliation, Alvarado was targeted by a group of ten Marines who carried out a hazing—commonly known in Marine culture as a "Code Red." The group blindfolded and bound Alvarado, stuffed a pillowcase into his mouth, and began cutting his hair. According to reporting by Boston.com, Cox noticed Alvarado had stopped breathing and the hazing was immediately halted; Alvarado survived after receiving medical attention.

“Don't take him up to the roof and throw him off and kill him, but if he were to fall down the stairs in the middle of the night, oh, well,”
—Cox quoted in the Natick Bulletin describing a purported instruction from a platoon commander.

Court-Martial And Aftermath
Ten Marines faced court-martial proceedings. Seven accepted plea deals; Cox and two others pleaded not guilty and took their cases to trial. Cox was represented by Donald Marcari, a young military-defense lawyer. A jury convicted Cox of simple assault (a misdemeanor) but acquitted him of aggravated battery. He remained in the Marine Corps and received an honorable discharge in 1989.

Disappearance And Murder (1994)
On January 5, 1994, Cox—then working part time at UPS—was last seen at the apartment he shared with his girlfriend, Elaine Tinsley. That evening she returned home to find the truck in the driveway with keys in the ignition, apartment doors open, and their pet rabbit loose. Cox’s camouflage Marine jacket was missing.

Three months later, a passerby discovered Cox’s body along the Charles River near Medfield, Massachusetts. He was 27. Investigators reported one gunshot to the back of his neck and three in his torso—what his brother described as an "execution-style" killing. Authorities concluded Cox likely knew his killer; there were no signs of a struggle. The murder remains unsolved.

Possible Motives And The Investigation
Speculation about motive has included retaliation tied to the Guantanamo hazing, fallout from a combative radio interview Cox gave about Marines' conduct in Cuba, and possible links to suspicious activity Cox reported at UPS. None of these theories has been publicly confirmed by investigators. As of last reports, the case remains open; anyone with information is asked to contact the Norfolk District Attorney’s Office at 781-830-4800.

Cultural Legacy
Aaron Sorkin, inspired by court-martial transcripts and accounts from his sister, a Navy JAG lawyer who represented one of the Marines in the case, turned the events into the stage play and later a major film, A Few Good Men. The movie amplifies and changes elements of the real case—most notably by having the hazing victim die and by dramatizing a commanding officer’s confession—while the true events included a surviving victim and disputed command culpability.
"Axis Sally"
Key facts to remember: Alvarado survived the 1986 hazing; Cox was convicted only of a misdemeanor and honorably discharged; Cox disappeared in January 1994 and was found murdered in April 1994; the case is unsolved.
