Although Ryshkevich freed himself from the safety belts in the boat, he sank into the water near the Danube in Linz-Ottensheim on Wednesday as rescuers approached. Police say Ryshkevich's body was recovered from the murky, 2.4-meter (8-foot) deep water more than two hours later. Police say reasons for the broken equipment "are yet unknown and are currently under investigation."
Ryshkevich was competing at his third world championships. The races are qualifying events for the 2020 Tokyo Olympics and Paralympics. International Paralympic Committee president Andrew Parsons says the incident is a "terrible tragedy."
