There are some factors that suggest the swine flu killing people in Mexico may be a biological weapon, but obviously no such conclusion can be drawn at this time. The World Health Organization and the U.S. government have been quick to deny such claims .
The swine flu virus is described as a completely new strain, an intercontinental mixture of human, avian and swine viruses. Tellingly, there have been no reported A-H1N1 infections of pigs.
According to a source  known to former NSA official Wayne Madsen, “A top scientist for the United Nations, who has examined the outbreak of the deadly Ebola virus in Africa, as well as HIV/AIDS victims, concluded that H1N1 possesses certain transmission “vectors” that suggest that the new flu strain has been genetically-manufactured as a military biological warfare weapon.
Madsen claims that his source, and another in Indonesia, “Are convinced that the current outbreak of a new strain of swine flu in Mexico and some parts of the United States is the result of the introduction of a human-engineered pathogen that could result in a widespread global pandemic, with potentially catastrophic consequences for domestic and international travel and commerce.”
However, it’s important to stress that it is far too early to make this assumption. We have to bear in mind that the number of victims has been comparatively low when one considers the fact that hundreds of thousands in Mexico contract infectious diseases every year related to poverty like tuberculosis and malaria. 
Fort Detrick, the U.S. Army Medical Command installation that was the source of the 2001 anthrax attacks, is again attracting suspicion in light of the swine flu panic after it was revealed that criminal investigators are probing whether virus samples recently went missing from its biolabs.
“Chad Jones, spokesman for Fort Meade, said CID is investigating the possibility of missing virus samples from the U.S. Army Medical Research Institute of Infectious Diseases,” reports
In February, USAMRIID halted their work when virus samples were discovered that were not listed in its inventory. Criminal investigators from the U.S. Army Criminal Investigation Division unit at Fort Meade are now probing whether virus samples are missing from the Army’s top biolab, which also studies pathogens including ebola, anthrax and plague.
Obviously, in light of the current swine flu scare, and the new strain’s possible synthetic origin, the fact that virus samples may have gone missing from the same Army research lab from which the 2001 anthrax strain was released is extremely disturbing.
A 2008 FBI and DOJ investigation concluded that Bruce Edwards Irvins, a microbiologist, vaccinologist, and senior biodefense researcher at the United States Army Medical Research Institute of Infectious Diseases (USAMRIID) in Fort Detrick, Maryland, was responsible for mailing anthrax to members of Congress and the media in September and October 2001.
The fact that Irvins apparently committed suicide shortly before the announcement led many to suspect that he was a patsy in a wider plot. Despite the suspicious circumstances, no autopsy was carried out on Irvins’ body. His attorney was certain that Irvins, who had cooperated with the 6-year investigation, was innocent of the five anthrax deaths.
The Department of Justice initially considered Dr. Steven Jay Hatfill to be a strong suspect in the anthrax attacks, but he later sued the government and won $5.8 million in damages.
A New York Times piece  on Irvins’ suicide asked the hypothetical question: “What if Dr. Hatfill had committed suicide in 2002, as friends feared he might? Would the investigators have released their evidence and announced that the perpetrator was dead?”

Fears that a mass pandemic was being readied as a biological attack have rumbled on in the conspiracy community ever since 9/11. Investigators point to the
