He was found dead on March 24, 2015, in Kaspiysk in suspicious circumstances, although the official investigation concluded he died from natural causes. Sadval movement issued a statement in which its leader, Nazim Hajiyev, publicly stated that he was convinced that Magomedragimov had been killed due to his activism (Hajiyev himself would be murdered a year later). In 2021 investigation by Spiegel, Bellingcat and The Insider, suggested that Magomedragimov might have been the victim of the same FSB team that was involved in the Poisoning of Alexei Navalny.
