Maurice Généreux is a Canadian physician who was convicted in 1998 of prescribing medications to two HIV positive men in Toronto, Canada in 1996; medications that subsequently allowed the men, Mark Jewitt and Aaron Mcginn, to commit suicide in 1996. Généreux was the first doctor in North America to be convicted of assisting a suicide (followed in 1999 by Jack Kevorkian).
Jack Kevorkian was the second doctor in North America to be convicted of assisting a suicide.
The context stated that Généreux was the first doctor convicted of assisting a suicide and was followed by Jack Kevorkian a year later. This makes Kevorkian the second doctor convicted of assisting a suicide. I think the system had trouble with my statement because I phrased the statement quite differently (and more specifically) than the context stated the same information.
