"Joseph Michael Swango (born October 21, 1954) is an American serial killer and former licensed physician. It is estimated that Swango has been involved in as many as 60 fatal poisonings of patients and colleagues, though he only admitted to causing four deaths. He was sentenced to life imprisonment...
...Swango was born in Tacoma, Washington and raised in Quincy, Illinois, the middle child of Muriel and John Virgil Swango. Swango's father was a career U.S. Army officer who served in the Vietnam War and was troubled by alcoholism...Upon his return from Vietnam, Swango's father became depressed...
...Even earlier, several students and faculty members had raised concerns about his competence to practice medicine...Swango got a surgical internship at Ohio State University Medical Center in 1983, to be followed by a residency in neurosurgery. While he worked at the Rhodes Hall wing at Wexner, nurses noticed that apparently healthy patients began dying mysteriously with alarming frequency. Each time, Swango had been the floor intern. One nurse caught him injecting some "medicine" into a patient who later became strangely ill. The nurses reported their concerns to administrators, but were met with accusations of paranoia.
...Soon, many of the paramedics on staff began noticing that whenever Swango prepared the coffee or brought any food in, several of them usually became violently ill, with no apparent cause...
...In 1989, Swango, now released from prison...He then found a job as a laboratory technician for ATICoal in Newport News, now Vanguard Energy, a division of CITA Logistics. During his time there, several employees sought medical attention with complaints of persistent and increasing stomach pains...
...In 1991, Swango legally changed his name to Daniel J. Adams and tried to apply for a residency program at Ohio Valley Medical Center in Wheeling, West Virginia. In July 1992, he began working at Sanford USD Medical Center in Sioux Falls, South Dakota.
...The AMA temporarily lost track of Swango, who managed to find a place in the psychiatric residency program at the State University of New York at Stony Brook School of Medicine. His first rotation was in the internal medicine department at the Veterans Affairs Medical Center in Northport, New York. Once again his patients began dying for no explicable reason.
...In November 1994, he went to Zimbabwe and used forged documents to obtain a job at Mnene Lutheran Mission Hospital in the center of the country. Again, his patients began dying mysteriously...
...he hired prominent lawyer David Coltart to enable him to return to clinical practice. He also appealed to the authorities at Mpilo Hospital, Bulawayo, to allow him in the interim to continue working voluntarily there.
...until mid-1994, when the FBI found out he was living in Atlanta and working as a chemist at a computer equipment company's wastewater facility...
...Swango had sensed that the net was closing on him; he crossed the border to Zambia and subsequently to Namibia where he found temporary medical work. He was charged in absentia with poisonings. In March 1997, he applied for a job at the Royal Hospital in Dhahran, Saudi Arabia...
...As part of that investigation, prosecutors exhumed the bodies of three patients and found poisonous chemicals in them. They also found evidence that Swango paralyzed patient Baron Harris with an injection of what was supposedly a sedative. The sedative caused him to lapse into a coma...
...Swango lied about the death of Cynthia Ann McGee, a patient he treated during his internship at OSU. Swango claimed she suffered heart failure; he had killed her by giving her a potassium injection that stopped her heart..."
