Daphne Anne Caruana Galizia (née Vella; 26 August 1964 – 16 October 2017) was a Maltese writer, journalist, blogger and anti-corruption activist, who reported on political events in Malta. She was known internationally for her investigation of the Panama Papers and subsequent assassination by a car bomb. Caruana Galizia focused on investigative journalism, reporting on government corruption, nepotism, patronage, and allegations of money laundering, links between Malta's online gambling industry and organized crime, Malta's citizenship-by-investment scheme, and payments from the government of Azerbaijan. Caruana Galizia's national and international reputation was built on her regular reporting of misconduct by Maltese politicians and politically exposed persons.
It's why the Panama papers etc was done by a consortium of journalists. Much safer as killing one journalist or two doesn't make any difference to the end publication.
