(Gladstone, OR)  --  Officials say crews have suspended their search for a swimmer who disappeared after he jumped into the water at High Rocks Park in Gladstone.  Authorities say the man jumped in from the rocks around 7:20 last night, came up momentarily, then went back under and never resurfaced.  Around 9 p.m., the search was suspended by the Clackamas County Sheriff's Office Water Rescue Team because of the strong current.
