John Muhammad & Gulf War syndrome
The alleged Washington sniper, John Allen Muhammad, may have been exposed to chemical weapons that have been linked to Gulf War Syndrome, an illness which experts said can result in unexplained bouts of intense violence.
“Once it came out that he had a military background, I said this must be a Gulf War veteran,†said Dr. William E. Baumzweiger, a Los Angeles neurologist and psychiatrist who specializes in treating Gulf War Syndrome patients. “There is no doubt that a small but significant number of Gulf War veterans become homicidal†because of Gulf War Syndrome, said Baumzweiger.
