Dorothy Kilgallen — the journalist and television personality who died suddenly in November 1965 — made a few intriguing remarks to people close to her, including her hairdresser, in the days just before her death.
From what’s been reported in biographies, press accounts, and later investigations:
đź’‡ What she told her hairdresser
Kilgallen’s longtime hairdresser, Marc Sinclaire, later said she had confided that she was working on a huge story — something that would “blow the lid off the country.”
He recalled her saying, just days before her death: “If the wrong people knew what I know, it would cost me my life.”
She also told him that she had just interviewed a “key witness” in New Orleans related to the assassination of President John F. Kennedy.
đź“– Context
Kilgallen was one of the few journalists to interview Jack Ruby, the man who killed Lee Harvey Oswald, and she was pursuing her own investigation of the Kennedy assassination.
She had been writing critical columns about the Warren Commission and reportedly was preparing a book manuscript.
On November 8, 1965, she was found dead in her Manhattan townhouse at age 52. The official cause was “acute ethanol and barbiturate intoxication.” Many found the circumstances suspicious.
🧩 Takeaway
Her hairdresser’s account has fueled decades of speculation that Kilgallen’s death might not have been accidental, since she herself had expressed fear that her reporting on JFK could endanger her.
Would you like me to also give you a summary of what other friends and colleagues (besides her hairdresser) remembered her saying in those last days?
Alright — here’s what other people close to Dorothy Kilgallen reported about her last days, in addition to what she told her hairdresser:
—
* He later said Dorothy had told him she was on the verge of *“the biggest scoop of her life.”* * She said she had “cracked the case wide open” regarding President Kennedy’s assassination.
—
* He told acquaintances that Dorothy had been unusually excited about her work in the days before she died. * He said she often stayed up late, writing notes and keeping files about her investigation.

—
* One of her assistants recalled that Dorothy kept a *manila folder labeled “JFK”* with her notes. * This folder was reportedly missing after her death, adding to the speculation.
—
* Multiple people — hairdresser, colleagues, friends — all remembered her expressing confidence that she had explosive information tied to the Kennedy assassination. * She also expressed fear: that if the “wrong people” knew what she knew, she could be killed. * After her death, some of her notes and manuscript material on the assassination reportedly vanished, which intensified suspicions.

Would you like me to outline the different theories people have proposed about *what exactly she might have discovered* before she died?
Okay — here’s a structured overview of the main theories about what Dorothy Kilgallen might have discovered (or believed she had discovered) before her sudden death in 1965:
—
* Dorothy was one of the very few journalists to privately interview Jack Ruby (the man who shot Lee Harvey Oswald). * She hinted in her columns that Ruby had deeper ties — possibly to organized crime or intelligence circles — that the Warren Commission had overlooked or downplayed. * Theory: She uncovered evidence that Ruby and Oswald were *not* “two lone nuts,” but part of a larger network.
—
* Kilgallen had covered organized crime extensively earlier in her career. * Some believe she learned that mob figures (particularly in New Orleans and Chicago) had roles in the assassination or its cover-up. * New Orleans mob boss Carlos Marcello and his network are often suggested as her investigative target. * Supporting detail: She had reportedly traveled to New Orleans shortly before her death, supposedly to meet a “key witness.”
—
* In the 1960s, suspicions of CIA involvement in Kennedy’s death were already circulating. * Dorothy may have been chasing leads suggesting that Oswald’s movements in Mexico City (and other intelligence connections) had been misrepresented. * Theory: She had obtained inside information implicating elements of the CIA in either foreknowledge or suppression of evidence.
—
* Some accounts suggest Dorothy had tracked down a witness whose testimony was omitted or ignored by the Warren Report. * She allegedly told friends this source confirmed aspects of a conspiracy. * Her comment to her hairdresser — “If the wrong people knew what I know, it would cost me my life” — is often tied to this theory.
—
* Dorothy was under contract to write a book about the Kennedy assassination. * After her death, the draft manuscript and key notes disappeared from her townhouse. * Theory: She had already put sensitive findings on paper, and those documents were deliberately removed before the public could see them.
—
* All focus on her belief that the official “lone gunman” story was false or incomplete. * Most involve either mob ties or government/intelligence connections. * Her death — ruled a mix of alcohol and barbiturates — seemed suspicious because she was not known as a heavy drinker or drug user, and because her files went missing immediately afterward.
—
✅ Bottom line: While we don’t know exactly what Dorothy Kilgallen discovered, the theories cluster around:
* Ruby’s deeper connections, * Mob involvement (especially New Orleans), * Possible CIA links, and * Suppressed evidence or testimony.
Her remarks in those final days suggest she believed she had explosive, potentially dangerous information — but her sudden death left only speculation and missing papers.

Would you like me to also give you a timeline of her last week — who she met, what she said, and what happened the night she died?
Here’s a timeline of Dorothy Kilgallen’s last week in November 1965, pieced together from biographies, newspaper accounts, and recollections of friends and colleagues. It shows why her death still raises questions:
—
* Dorothy is actively investigating the JFK assassination. * She travels to New Orleans, reportedly to meet a “key witness” connected to the case (possibly with mob ties). * Returns to New York with renewed urgency, telling friends she has the *“scoop of a lifetime.”*
—
* At the TV studio for *What’s My Line?* rehearsals, she tells her hairdresser, Marc Sinclaire:
* She mentions having notes for her upcoming JFK book and suggests she’s uncovered a connection others missed.
—
* She lunches with friends and again mentions she’s on to something big. * She says she’ll be writing late into the night over the weekend.
—
* Seen socially at the Regency Hotel with a male acquaintance. * Friends recall she seemed “buoyant, excited, and secretive” — saying she couldn’t yet share details but would “soon.”
—
* Appears live on *What’s My Line?* looking cheerful and in good form. * Afterward, she goes to the Regency Hotel for drinks with a friend, then returns home around 1 a.m. * She reportedly goes upstairs to her private writing room (she called it the “den”), where she often worked late into the night on her columns and JFK notes.
—
* Around noon, her maid and hairdresser find her body in a bedroom she *rarely used* (not her usual bedroom). * She is sitting up in bed, still in makeup and false eyelashes, with notes and papers nearby. * The official cause: acute ethanol and barbiturate intoxication (alcohol + Seconal). * The death is ruled “accidental,” though some argue suicide or foul play.
—
* Dorothy was not known as a heavy drinker or reckless pill user. * The bedroom where she was found was not her normal one. * Her JFK research file (manila folder and notes for her book manuscript) was missing from her townhouse and never recovered. * Multiple friends recalled she had been optimistic, energetic, and forward-looking — not suicidal — in those final days.
—
✅ Summary: In her last week, Kilgallen repeatedly told friends, colleagues, and her hairdresser that she had uncovered explosive information on the JFK assassination, and was preparing to publish it. Less than 24 hours after her final *What’s My Line?* appearance, she was dead, and her research papers had vanished.
