All four suspects involved in the tragic Crocus City concert hall attack have been remanded into pre-trial detention until May 22. They are facing charges of committing a terrorist act, which, under the Russian Criminal Code, carries a maximum penalty of life imprisonment.
According to state media news agency TASS, three of the defendants have pleaded guilty to all charges. The suspects are all from Tajikistan, a former Soviet republic, and were in Russia on either temporary or expired visas.
