The next day, the Nur-Sultan city police reported that Agadil had died in a pre-trial detention center due to suspected heart failure.

[11] Three days after his death, the President of Kazakhstan Kassym-Jomart Tokayev, without waiting for the end of the investigation and the official results of the forensic medical examination, made a statement in which he supported the initial version voiced by the police:[12] “Given the great public outcry, I carefully read this case.

According to political scientist Dosym Satpayev, the death of Dulat Agadil, along with other negative events for the authorities, including the 2020 Dungan–Kazakh ethnic clashes, became the reason for the release of the former head of Kazatomprom, Mukhtar Dzhakishev from prison.

[13][14] Dulat Agadil is survived by his wife, Gülnar and six children: daughter Qymbat, and sons Nurbolat, Aibolat, Janbolat, Qasymhan and Abylaihan.

After his death, his close friends, associates, activists and all concerned citizens of Kazakhstan from all over the world, jointly built a house for his family by providing money, information support, and directly taking part in the construction.

After the end of the lunch, the audience moved to Agadil's grave to read a prayer, as a result of which about a hundred participants were subjected to administrative fines, detentions and arrests on charges of the event not being coordinated with the authorities.
