The death toll in the military barracks collapse in the Siberian city of Omsk rose to 24 after a paratrooper died in hospital on July 15.
Russian Defense Ministry spokesman General Igor Konashenkov told journalists that the paratrooper was treated at the Kirov Military Medical Academy but died as a result of his injuries in the July 12 accident.
All four floors collapsed in one section of the building as 42 Russian paratroopers were resting in the evening on July 12.
Authorities blamed construction workers for the collapse.
The Investigative Committee has opened a probe into negligence, violation of safety rules, and abuse of power.
Those who are found guilty would face up to 10 years in prison the committee said.
