The Russian Investigative Committee said it believed someone planned and ordered the car explosion that killed Darya Dugina, based on evidence already collected from the blast. "Taking into account the data already obtained, the investigation believes that the crime was pre-planned and was of an ordered nature," the investigative committee said in a statement Sunday.

Dugina died at the scene after "an explosive device, presumably installed in the Toyota Land Cruiser, went off on a public road and the car caught fire" at around 9.00 p.m. local time on Saturday, near the village of Bolshiye Vyazemy, according to the press service of the Russian Investigative Committee, as reported by the Russian state news agency TASS.

Dugina's father is a Russian author and ideologue, credited with being the architect or "spiritual guide" to Russia's invasion of Ukraine. He is purported to have significant influence over Russian President Vladimir Putin and was described as "Putin's Brain" by Foreign Affairs magazine.
