CHENEY ? A 16-year-old Wichita boy and 13-year-old girl from Mesa, Ariz., have died in separate accidents at south-central Kansas’ Cheney Lake this holiday weekend.

The Wichita Eagle reported Gabriel Salinas drowned Saturday afternoon after he waded past a roped-off swimming area. Park ranger Mike Satterlee says Salinas didn’t know how to swim and struggled when he stepped into a deep hole.

His body was located about two hours later.

On Friday, Nicole Whitney Smith died in a boating accident. Reno County Undersheriff Sheldon Stewart says she fell off her wakeboard and was struck by the boat pulling her.

Stewart says she was dead when emergency workers arrived.

Smith has been visiting relatives in the Wichita area.
