Investigators initially considered three possibilities for the cause of the fire: arson, recklessness with fire and electrical appliances, and an electrical
short circuit.
Iryna Venediktova, the prosecutor general of Ukraine, declared the preliminary cause of the fire was the "careless handling of electric heating devices". The police chief of Kharkiv, Andrii Rubel, declared that the owner of the nursing home, Slavik Akopian, was remanded to a pre-trial detention centre and that the six other nursing homes that Akopian owned were closed. Akopian appealed to be released under
house arrest, citing his age (he was 67 at the time of the trial) and large family (he had four children). The prosecutor, Oleksandr Dobroskok denied his request because Rubel's neglect of fire safety led to a "terrible traged[y]". , all four defendants in the trial were released on bail. == Responses ==
