“The bodies of three people were found, without signs of life: a man born in 1961 and two women, born in 1963.
The preliminary cause of death is carbon monoxide poisoning as a result of violation of the rules for the use of gas heating appliances, ”the statement said.
It is noted that a pre-investigation check has begun on this fact.
Earlier, investigators opened a criminal case on the death of four men from carbon monoxide poisoning in a private house in the Kovylkinsky district of Mordovia.
