Brazilian doctor 'may have killed 300 patients'
A Brazilian doctor charged with killing seven patients to free up hospital beds for those with private health insurance may have been responsible for 300 deaths in total, the country's health ministry has said.
Officials investigating Virginia Soares de Souza (56) are reviewing more than 1,800 medical records at the hospital where she was the head of intensive care since 2006.
If the number of deaths suspected of being linked to Ms de Souza is proven, she would have been a more prolific serial killer than the British doctor Harold Shipman, who killed at least 215 people.
Dr de Souza, a widow who worked at the Evangelical Hospital in the city of Curitiba, is accused of masterminding a "gang of death" involving several members of her team.
Dr de Souza is suspected of repeatedly giving patients the muscle-relaxing drug Pavulon and turning off their oxygen machines.
Dr de Souza denies the charges and defended her record at the hospital where she has worked since 1988.
