Draga was the fourth daughter of Panta Lunjevica, a prefect of the Aranđelovac area, and wife Anđelija (née Koljević).

[1] Draga was the granddaughter of Nikola Lunjevica, a blood relative of Princess Ljubica of Serbia and close comrade of Prince Miloš, her husband's great-granduncle.

[4] Despite Draga (aged 33) being ten years older than King Aleksandar, the couple married on 5 August 1900 in a formal ceremony.

When Aleksandar announced their engagement, public opinion turned against him, viewing him as a besotted young fool in the power of a "wicked" seductress.

Troops led by other officers involved in the conspiracy were deployed near the palace, and the royal guards did not offer effective resistance during the confusion after the electric lighting of the building was turned off.

However an aide of the king was captured and, either out of sympathy for the conspiracy or out of fear for his own life, revealed that they were hiding in a large built-in wardrobe off their bedroom.

Emerging partially dressed, the couple were murdered with sword thrusts and pistol shots by the officers, some of whom were reportedly drunk.

It was not until 19th June that the Lunjevica sisters, including the elder one Hristina Petrović with her children, left the country and settled permanently in Switzerland.
