"Hawaii Island police also launched a missing person investigation for Mark Knittle, described as 5-feet-10 inches, 185 pounds, with curly brown hair and white mustache and beard. It was reported to police that on Sunday at 5 a.m., Knittle and a friend were fishing near the "C" buoy, four miles outside of the Honaunau Boat Ramp, when Knittle hooked an ahi. The friend heard Knittle say, "the fish is huge," then he saw Knittle go overboard. The friend attempted to grab the line but was unsuccessful, police said, and the man disappeared into the water within seconds."..............
