Since the dawn of the 21st century, observers have pointed out that numerous prominent scientists started to pass away under questionable circumstances. Some were victims of homicide, while others seemed to have perished in unfortunate mishaps.
Although the majority accepted the official accounts of these scientists' deaths, a few delved deeper, giving rise to the conspiracy theory that they were systematically 'removed.' Investigations revealed that several of these scientists had covert connections to intelligence agencies, fueling speculation that they were deliberately targeted. Below are ten such individuals.
10. Dr. Rodney Marks

Dr. Rodney Marks, an Australian astrophysicist, succumbed to severe methanol poisoning. The exact cause of his poisoning, however, remains unclear. Authorities dismissed suicide as a possibility during the subsequent inquiry. As years go by, it seems increasingly probable that the circumstances surrounding his death will stay unresolved.
At the time of his passing on May 12, 2000, Marks was working on a National Science Foundation research initiative in Antarctica under the Smithsonian Society. His health had rapidly deteriorated the day before, with symptoms including vomiting blood as his condition worsened.
Interestingly, investigators expressed dissatisfaction with the National Science Foundation, citing a notable lack of collaboration that hindered the investigation. Coroner Richard McElrea remarked that he was “not fully convinced that all pertinent information and reports” had been provided to New Zealand authorities.
9. Dr. Don Wiley

Dr. Don Wiley’s body was recovered from the Mississippi River on December 20, 2001, with both Arkansas and Tennessee police classifying his death as a homicide. The biophysics specialist had last been spotted on November 15, over a month prior. His rental car was discovered abandoned the next day on a Tennessee bridge. The FBI later took over the investigation, concluding that his death was accidental, suggesting he had fallen from the bridge soon after leaving his car.
Despite the FBI’s findings, doubts persisted. For one, the bridge featured a 2-meter (6.5 ft) high fence, making an accidental fall unlikely, if not impossible. Additionally, his death occurred shortly after the Anthrax attacks in the U.S., leading some to speculate that Dr. Wiley, being one of the few experts capable of tracing the source of the deadly substance, may have been targeted.
8. Dr. Tanya Holzmayer

In 2002, Dr. Tanya Holzmayer, a 46-year-old geneticist, was fatally shot by her colleague, Guyang Matthew Huang, when she opened her door to pay for a pizza delivery. The tragic incident was witnessed by her teenage son, who was left in shock. Mountain View, California, Holzmayer’s residence, had recorded just one homicide in the entire preceding year.
Huang fled the scene in his vehicle, but his body was discovered soon after. It appeared he had committed suicide. While the police were unable to determine a clear motive, some speculated that Huang’s actions were driven by revenge, as Holzmayer had previously dismissed him for violating company policies.
Staff at PPD Discovery, where both Holzmayer and Huang had been employed, were directed to refrain from speaking to the media about the incident, adding an additional layer of intrigue to the already mysterious case.
7. Dr. Benito Que

On November 12, 2001, Dr. Benito Que’s lifeless body was found outside his laboratory at Miami Medical School in Florida. He had suffered severe injuries, suggesting he was the victim of a violent robbery. Reports from local media at the time mentioned sightings of four individuals dressed in dark clothing and carrying baseball bats near the scene around the time of the scientist’s death.
Police, however, dismissed these claims, attributing Que’s death to cardiac arrest. Their refusal to provide further details to the public only intensified speculation about a potential cover-up. Que, a cell biologist, was actively researching infectious diseases, including HIV, at the time of his untimely demise.
6. Dr. Robert Leslie Burghoff

Robert Leslie Burghoff’s death was no accident. A van was deliberately driven onto the pathway where he was walking at the Texas Medical Center on November 20, 2003, striking him with full force. The vehicle fled the scene immediately, leaving the biochemist’s body behind.
At the time of his death, Burghoff was investigating a flu outbreak affecting cruise ships. Interestingly, Texas was also experiencing a flu epidemic around the same period. As an expert in gene-mapping, some speculated that his death, clearly a targeted hit-and-run, might have been linked to his groundbreaking research.
5. Drs. Vladimir Korshunov and Alexi Brushlinski

Drs. Vladimir Korshunov and Alexi Brushlinski, Russian microbiologists, were killed in Moscow within a two-week span in early 2002.
Brushlinski, a distinguished member of the Russian Academy of Science, was fatally attacked on January 28 in what authorities described as a “bandit assault.” He died from severe beating.
Nearly two weeks later, on February 8, Korshunov met a similar fate, beaten to death near his home and abandoned on the street. At the time of his death, Korshunov was leading the microbiology department at the Russian State Medical University.
While officially classified as random acts of violence, both murders have sparked skepticism among conspiracy theorists, who question the official narrative.
4. Dr. Eugene F. Mallove

Eugene Mallove, a prominent figure in the contentious field of free energy, was found dead in the driveway of his childhood home. His death quickly became a focal point for conspiracy theorists, who argued it was a targeted assassination rather than a crime stemming from a dispute over unpaid rent and eviction.
At the time of his death in May 2004, Mallove had been leasing his childhood home to the Schaffers. Their son, Chad, along with his girlfriend, Candace Foster, and friend Mozzelle Brown, were later charged with the murder. Investigators revealed that Chad and Brown had returned to the rented property, brutally assaulted Mallove, and, with Foster’s assistance, staged the scene to resemble a robbery.
Despite the clear link to the Schaffers, it took authorities several years to piece together the evidence and make arrests, adding an air of mystery to the case.
3. Dr. Jeong Im

The 2005 killing of Jeong Im, a retired University of Missouri professor and renowned protein chemist, remains a fascinating case.
Firefighters responding to a car fire on the third floor of a parking garage found Im’s body in the trunk after extinguishing the flames. He had suffered multiple stab wounds to his chest, indicating he was likely deceased before being placed in the vehicle.
Nearly a decade later, in 2013, the murder was attributed to Timothy Hoag, a career criminal who had leaped to his death from the same garage where Im’s body was discovered.
2. Dr. Ian Langford

Despite the unusual circumstances of Dr. Ian Langford’s death on February 11, 2002, police ruled it non-suspicious within 48 hours. His partially unclothed body, bearing injuries, was found in a peculiar position beneath a chair in his home. Authorities suggested the wounds were either self-inflicted or the result of an earlier accident. Unofficial reports, however, claimed his home was covered in blood when his body was discovered.
Langford was a renowned environmental risk researcher at the University of East Anglia, where he had worked for eight years. Colleagues hailed him as “one of Europe’s foremost experts” in his field.
1. Dr. John Mullen

John Mullen, a physicist and nuclear research scientist, passed away unexpectedly in June 2004 due to arsenic poisoning. Investigators suspect the fatal dose was delivered via a health drink he had ingested. At the time of his death, Mullen was engaged in contract work for Boeing.
In a further bizarre turn of events, his girlfriend, Tamara Rallo, who was on the verge of being arrested for her alleged involvement in his murder, was discovered dead at her residence. Authorities did not disclose whether her death was a suicide or a homicide, leaving the case unresolved and ensuring no trial for Mullen’s death.
