Why murdered Maltese journalist Daphne Caruana Galizia is back in the news

(CNN)Daphne Caruana Galizia, 53, was a leading anti-corruption journalist from Malta, killed in a car bombing near her home in 2017. Her family say she was "assassinated" because of her work uncovering alleged corruption in the Maltese government.

Caruana Galizia first earned her reputation as an activist in 1982 when she landed in jail at the age of 18, for protesting against what she felt was a corrupt government. She spent her early career writing for Malta's largest publications, including the Sunday Times of Malta and the Malta Independent, for whom she wrote regular columns until her untimely death.
Even after her death, her personal blog Running Commentary still regularly attracts more views than the combined circulation of all of Malta's newspapers, according to the Daphne Caruana Galizia Foundation, established by Caruana Galizia's sons and husband.
    In 2016, Caruana Galizia broke a story about a string of secret Panama-based companies tied to Maltese politicians on her blog, including allegations of corruption against Maltese Prime Minister Joseph Muscat's wife. The couple have denied the allegations.
    Her work laid the groundwork for the publication first of the Paradise Papers and later the Panama Papers by the International Consortium of Investigative Journalists.
    Caruana Galizia's work made her many powerful enemies while she was alive, and she was sued for libel on multiple occasions. The many threats she received have contributed to the difficulty in determining just who was responsible for her death.

    What happened to her?

    Caruana Galizia died on October 16, 2017, when her rented Peugeot 108 was detonated by a remote control device on a country lane near her home in Bidnija, Malta. Her son Matthew Caruana Galizia, told CNN that she was driving a rental car at the time, out of fear that someone might target her car in an attempt to kill her.
