Since election day 2016 at least 9 Russian politicians, diplomats or officers have died under suspicious circumstances. Some cases seem likely to be politically motivated assassinations, while others seem more benign. Most likely the deaths are a mixture of assassinations and natural causes. What does seem highly unusual is the number of deaths in a short time period. The causes of death are a mixture of gun shot wounds, accidents and heart problems. Note that thanks to a 1975 congressional inquiry by Senator Frank Church and video footage of congressional testimony, we know that technology for a ‘heart-attack’ gun exists at least in U.S. hands.

1. Sergei Krivov, died 11/8/2016.

Krivov was found just before 7 a.m. on Election Day, lying on the floor of the Russian Consulate on the Upper East Side. Who he was and how he died is still unclear.

English-language news reports said Krivov was a security officer. But a November report from Sputnik, the English-language Russian media outlet, says he was a consular duty commander, which would give him access to a top secret coding device.

The Russian consulate originally said Krivov fell to his death from the roof, but then changed their story to death by heart attack. However, on the day of his death the NYPD reported Krivov was found dead with a head wound. The Manhattan medical examiner ruled Krivov died due to internal bleeding related to a tumor and found no evidence of head trauma.

Krivov’s address is also mysterious. His address, listed in the NYPD’s files, at 11 E. 90th St., wasn’t a residence. It’s a Smithsonian-owned office building. The NYPD insisted that 11 E. 90th St. was the address they had been given for Krivov, apparently by Russian consular officials. Additionally Krivov was described as a Manhattan resident though there is no trace of Krivov in public records.

2. Yves Chandelon, died 12/12/16.

Yves Chandelon

Chandelon, a 62 year old auditor general for NATO was found dead of a gunshot wound to the head in his car. As part of his job, Chandelon investigated the funding of terrorist organizations. The medical examiner ruled his death a suicide but his family raised many suspicions. One, Chandelon was the registered owner of three guns but the gun found in the car was not his. Two, local media reported Chandelon had the gun in his right hand despite being left handed. Three, Chandelon also possibly told family members that he felt threatened and received strange phone calls. However, it’s also reported that a suicide note was found in the glove box believed to be in Chandelon’s handwriting.

3. Andrei Karlov, died 12/19/2016.

Andrey Karlov

Karlov, the Russian Ambassador to Turkey, was killed while giving a speech at an art gallery in Turkey by a 22-year-old off-duty Turkish police officer. The assailant was dressed in a suit and tie and calmly fired point-blank at Karlov while he spoke to journalists. A video of the attack shows the assassin yelling “Don’t forget Aleppo, don’t forget Syria!” and “Allahu Akbar” after killing Karlov. The assassin was able to gain entrance to the event by showing his Turkish police ID. Motive behind the attacks is disputed. Some blame Islamic extremism and anger over Russia’s role in Syria. However, Russian politicians have blamed the attack on NATO and ‘The West’, accusing them of orchestrating a false flag attack to  ruin Turkey-Russia relations.

4. Petr Polshikov, died 12/19/2016.

Petr Polshikov

On the same day as Andrei Karlov’s assassination in Turkey, Polshikov was found dead with a gunshot wound to his head in his home in Moscow. Polshikov is reported to have been a senior figure in the Latin American department of Russian foreign ministry. According to the Moscow newspaper, Moskovskij Komsomolets, Polshikov’s wife found him in their bedroom with a pillow over his head. A spokesman from the Russian Foreign Ministry said Polshikov’s death was likely an accident and had nothing to do with his official government duties.

5. Oleg Erovinkin, died 12/26/16.

The ex-KGB Chief Oleg Erovinkin was found dead in Moscow in the back of his Lexus from a supposed heart attack. Erovinkin was the top subordinate of Igor Sechin, an oligarch who runs Russia’s state owned Roseneft oil company. Sechin is named throughout the Trump-Russia ‘Golden Showers’ dossier written by MI6 agent, Christpher Steele. Erovinkin is believed to have been Sechin’s liaison with Putin and a key source in the dossier. Considering the ties to the Trump dossier many question the heart attack cause of death story.

6. Andray Malanin, died 1/9/17.

Vitaly Churkin

Vitaly Churkin, the Russian ambassador to the United Nations died suddenly at age 64 in New York. Local law enforcement claimed he died of cardiac arrest while at the Russian Mission on East 67th Street. However, medical examiners performing his autopsy said that more tests were needed to determine how and why he fell ill in his office and later died in a hospital. Further testing usually involves toxicology reports as well as other tests. Weeks later the U.S. State Department instructed the NYC’s chief medical examiner to not publicly disclose Churkin’s manner of death. The State Departmnet claimed Churkin’s diplomatic immunity survived his death and that Russian officials had already complained about the disclosing of details related to Churkin’s death.

9. Denis Voronenkov, died 3/23/17.

Denis Voronenkov

Voronenkov and his wife were former Russian parliamentary members who had fled to Ukraine after speaking out against Putin and Kremlin policies. Denis Voronenkov was shot while walking down a street in broad daylight. He was hit three or four times in the head and neck outside of the Premier Palace Hotel. Ukraine’s president, Petro Poroshenko, quickly pointed the finger at Russian authorities, calling the killing an act of “state terrorism”. Veronenkov is reported to have told friends he was receiving threats from the FSB, Russia’s modern day version of the KGB. He was also set to give testimony in a court case regarding Russia’s aggression in the Ukraine.
