Two more apparent cases of drowning are under investigation in different parts of the state. Authorities in the Okoboji area began searching Big Spirit Lake after a fisherman pulled in two boys who’d been clinging to a life jacket since their small boat capsized in high winds Thursday afternoon. A third teen went swimming back to their overturned boat but later disappeared and couldn’t be found. Near Glenwood, authorities last night still hadn’t identified a body pulled from Folsom Lake near where searchers found a parked truck. They weren’t saying if the man found floating face down had been swimming at the lake in Mills County. It’s not far from where a 19-year-old man drowned in April following a late-night drinking party.
