Missing WA fisherman probably drowned

A 70-year-old man who disappeared while fishing on Western Australia's southern coast was probably washed into the ocean, a coroner has concluded.

Jan Zapotocky was last seen in his garden on March 21, 2014 when he told his neighbour he planned to go fishing at Canal Rocks in Yallingup for a couple of days.

He never returned, but his vehicle was found in the Canal Rocks car park.

West Australian coroner Sarah Linton said in findings released on Friday that Mr Zapotocky probably drowned and may have been seriously injured on the rocks as he entered the water.
