Daria Dugina, 29, was driving a Toyota Land Cruiser Sunday when the vehicle exploded.

She was the daughter of Alexander Dugin, who is often called “Putin’s brain.” Dugin is a prominent Russian nationalist intellectual whose vision of a revived Russian empire came to influence Putin’s war in neighboring Ukraine.

Dugin was placed on western sanctions lists as a key proponent of the Kremlin’s forced annexation of Crimea from Ukraine in 2014. He also backed Russia’s decisions to send troops into Ukraine earlier this year.
