Kansas Department of Wildlife and Parks officers are still investigating a fatal boating accident that occurred Saturday afternoon at Perry Lake in Jefferson County.

The agency has identified 50-year-old Rafael Estrada, of Topeka, as the man killed on the lake’s upper Rock Creek arm.

Wildlife and Parks officers said according to a preliminary investigation it appeared Estrada was riding a jet ski or personal watercraft that turned in front of a boat. The boat then struck the jet ski.

An accident reconstruction team is still investigating, and a report may not be issued for several days, said Kevin Defisher, the regional boating officer for northeastern Kansas.
