Hopes fading for missing Adelaide swimmer

Grave fears are held for a swimmer missing for more than two days south of Adelaide

The 70-year-old Hackham man is thought to have gone swimming at Horseshoe Bay, near Port Elliott on South Australia's Fleurieu Peninsula, on Friday morning.

A two-day land and sea search has failed to locate the swimmer and hopes he will be found alive are fading.

Lifesavers, police, and SES and Country Fire Service crews will resume searching on Monday morning.
