Former male nurse admits to murdering seven people

Petr Zelenka, a former male nurse, who is charged with seven murders and ten attempted murders, has admitted to killing patients in hospital in order to “see some action”. Zelenka admitted to having injected patients on his ward with heparin – a blood thinning-drug – that kills if administered in excess. The hospital management eventually linked the series of deaths on the ward to the shifts of one of the male nurses. When the story broke several months ago, the public was shocked by how many murders Zelenka had got away with before being detected. He could face anything between 15 years and a life sentence.
