February 27, 1976 - Petr Zelenka
His position as a nurse gave him both access and cover — seven patients died by lethal injection across a span of seven months before the pattern was recognized. The hospital setting placed him among the most vulnerable people imaginable, and the killings unfolded quietly within an institution built around care.
From Wikipedia
Petr Zelenka (born February 27, 1976) is a Czech serial killer. As a nurse in hospital Havlíčkův Brod, 100 kilometres (62 mi) southeast of Prague, he murdered seven patients by lethal injection, and attempted to kill 10 others between May and December, 2006. He killed with a hidden vial of heparin — a blood-thinning drug causing internal bleeding when administered in large doses. His lawyer has been quoted as saying that Zelenka may have killed on an impulse to "test" doctors in Havlíčkův Brod, in the belief they were not good enough to discover the truth. In February 2008, Zelenka was convicted of killing seven patients and attempting to kill 10 others, and sentenced to life imprisonment.
