A court in Kazan, the capital of Russia's Republic of Tatarstan, has found all five defendants guilty in a high-profile case involving the sinking of an overcrowded tourist boat in 2011.
The judge read out the court's decision on July 3.
The "Bulgaria" sank in the Volga River on July 10, 2011, killing 122 people, including dozens of children.
The defendants include the director of the company that rented the vessel, the first assistant to the boat's captain, and regional river safety officials. The ship's captain died in the tragedy.
They were charged with abuse of power and violations of safety regulations that caused the deaths of more than two people.
Prosecutors have asked for sentences of between six and 14 1/2 years.
The "Bulgaria" tragedy was Russia's worst riverboat disaster in decades.
