Dalerdzhon Mirzoyev, 32; Saidakrami Rachabalizoda, 30; Mukhammadsobir Faizov, 19; and Shamsidin Fariduni, 25, were all charged with committing a group terrorist attack on Saturday by Badmanny District Court, per New York Post. They are all citizens of Tajikistan.
Mirzoyev, Rachabalizoda, and Fariduni were the 3 who admitted guilt after being charged. Faizov, the youngest, sat in a wheelchair with his eyes closed throughout the proceedings after being transported from a hospital.
Their charges carry a maximum sentence of life in prison. They will been held in pre-trial custody until May 22.
All four looked as though they had been beaten. Russian media outlets reported that they were tortured by security services during interrogation.
It was also reported that Rachabalizoda's ear was cut off, though it remains unverified.
Russian President Vladimir Putin addressed the nation on Saturday, reporting that the 4 suspects were captured and arrested that day by Russian authorities and 7 others were detained in suspicion of involvement in the terror attack.
He also stated that the suspects were captured while fleeing to Ukraine, which has been vehemently denied by Kyiv.
Putin said: "All the orchestrators, all those who are responsible for this crime will inevitably be found responsible. They will pay. We will identify everyone who stands behind the service, and they will pay."
