Video: Yes, There is a CIA Heart Attack Gun – A 1975 Congressional Hearing Confirmed it


In 1975 a congressional hearing revealed the CIA had numerous top-secret weapons including a gun that became known as the “CIA heart attack gun.”

In 1975 Congress investigated the CIA out of concern that former President Nixon may have used the CIA in an abuse of his powers. Nixon had resigned from office the previous year on August 9, 1974, fearing impeachment amidst the Watergate scandal. One revelation from the Congressional hearings was that the CIA had a secret assassination weapon otherwise known as the “heart attack gun”.

According to a video interview with Mary Embree, a former CIA employee, she was asked to help develop an “ice gun”. The CIA asked her to help find a poison which when administered would mimic a heart attack in a person but remain undetectable.

She said the heart attack gun reportedly could pierce through clothing, leaving no signs of impact on the skin except a small red dot. The targeted person would feel nothing beyond a slight sting, comparable to a mosquito bite.

In the 1998 video interview Embree said, “The poison was frozen into some sort of dart and then it was shot at very high speed into the person. When it reached the person it would melt inside them, and there would be a tiny red dot on their body, which was hard to detect. There wouldn’t be a needle or anything like that left in the person.”

The weapon, a modified Colt 1911, was mentioned during the infamous Church Committee probe in 1975, officially known as the United States Senate Select Committee to Study Governmental Operations with Respect to Intelligence activities. The investigation lasted nine months.

Footage from the probe in 1975 has gone viral in recent years, after being shared by historians and “conspiracy theorists”.

CIA Heart Attack Gun Leaves No Trace

The video footage doesn’t refer specifically to a “poison ice bullet” but does discuss how the gun being held in the video was developed to fire a dart like the one Embree described.

In a video from the 1975 hearing, Senator Frank Church asked CIA director William Colby, “Does this pistol fire the dart?”

Colby replied, “Yes, it does, Mr. Chairman, and a special one was developed which, potentially would be able to enter the target without perception.”

Colby also revealed the toxin would not appear in an autopsy—so there would be “no way of perceiving that the target was hit”.

Origins of the CIA’s Heart Attack Gun

Additionally, Colby disclosed a bit more history of what might have led to the creation of this gun. He stated that in 1952 the CIA began a super secret research program, code-named M.K. Naomi, partly to find countermeasures to chemical and biological weapons that might be used by the Russian KGB.

CIA researchers came up with an array of James Bond-like weaponry that could use shellfish toxin and other poisons as ammunition. A 1975 New York Times article details Colby’s testimony before the Congressional hearing where he reveals the extent of the secret CIA weapons program.

The Times reported, “The Naomi project operated in such secrecy, Mr. Colby said, that he learned of it only earlier this year when a former agency employee brought to his attention that two poisons had been kept in defiance of a Presidential order.”

Colby ordered an investigation into the poisons which found a seldom used CIA room that the Times reported contained “19 other lethal substances in addition to the shellfish toxin and cobra venom. These included poisons such as strychnine and cyanide pills as well as a material that causes abortions in animals. There was also a wide range of ‘incapacitating’ materials including those that lower blood pressure, cause temporary amnesia and impair kidney function.”

Charles Senseney, an engineer for the Defense Department, revealed at the probe that he had devised dart launchers that were disguised as walking canes and umbrellas.

Naturally, such intriguing mechanisms including the heart attack gun are a springboard for conspiracy theories and keyboard detectives.

Theories on Modern Day Usage of the CIA Heart Attack Gun

Indeed, the heart attack gun has returned to the spotlight once again when some sources theorized that it might be used against current president Donald Trump. These sources claimed that CNN’s persistent speculation on Trump’s waning health, particularly his heart, was in blatant opposition to reports of his “clean bill of health” from his doctor.

This led to the theory that perhaps the media was conditioning the public to believe Trump has a heart disease—as an alibi for an actual induced fatality via the infamous weapon.

Other theories have linked the weapon to the untimely and mysterious deaths of other public figures as well. The list includes: Clay Shaw, J. Edgar Hoover, Earlene Roberts, and Marilyn Monroe. There have also been speculations that former president John F. Kennedy had an unexplainable wound among other more conventional bullet wounds, after his assassination in 1963.

    Interesting weapon system. I’m sure they’ve been used many times since they were invented. Actual proof of their use is scarce though. There is proof that the umbrella gun was used in the 60s I believe. The Brits used it on a Russian if I remember correctly. It fired a tiny pellet of ricin into the victim’s leg. He died a day or 2 later.
    Interesting that the article mentions the fears of this weapon being used on tRump….one can hope….but honestly I don’t think it’s necessary. The man never exercises, he only sleeps 2-3 hours/night and he lives on fast food! He’s a walking heart attack! Or stroke. Either way I don’t think he’s long for this world. (Thank God!)
    In fact, I recently decided that tRump’s ONE AND ONLY redeeming quality is the fact that he’s old and unhealthy…the ONLY thing that’s good about him is that he probably won’t live much longer. Every single day when I wake up I turn on the tv or look at my iPhone hoping with every fibre of my being that there will be a Breaking News story stating that Orange Hitler choked to death on a double Big Mac, or had a stroke while taking a shit, or had a heart attack and died while he was in bed, on top of and inside of Ivanka. (And yes I mean Ivanka, not Melania)
    So far no luck, but hope keeps me going. After reading this article I have something new to hope for…that someone at the CIA will take seriously their oath to protect the constitution from all enemies both foreign AND domestic and pick up one of those ice guns or umbrella guns and put tRump out of our misery.

    Other than holding up a conventional gun with a scope and the say-so of someone who had no hand in how the gun actually works, is there any ACTUAL evidence that this thing exists?

    I ask because it seems unlikely that a battery and some kind of system to maintain the “ice bullet” could be in a handgun, scope or not, and especially not one from the 1970’s. Also, an “ice needle” couldn’t survive contact with the air, never mind the friction it’d experience flying towards its target. It’d vaporize the second you fired it.

    It seems unlikely to me that this is an actual weapon, and that the conspiracy community is taking a lot on faith from an organization that it supposedly trusts about as far as it can throw Mt. Rushmore. Further, if it existed, it would appear to be the kind of thing that the people who build their own EMP devices and 3D print guns should be able to replicate, given advances in manufacturing methods available to the amateur engineer.

    Again, is there any evidence it existed? Was one disassembled or demonstrated?
