Coast Guard and the Honolulu Fire Department continued the search for a missing 36-year-old Coast Guardsman Thursday, covering 1,233 square miles and 2,692 miles of trackline, but found nothing.

Fire officials will confer this morning with the Coast Guard to determine whether to continue the search, said fire Capt. Terry Seelig.

Petty Officer 1st Class Russell Matthews, an aviation survival technician from Air Station Barbers Point, was last seen 4:30 p.m. Tuesday in Pupukea. Police found his car Wednesday at a Kaena Point parking lot. He was reportedly distraught, police said.

A Coast Guard helicopter, plane and cutter continued searching Thursday, the Coast Guard said.

HFD’s helicopter crew as well as ground teams searched Thursday from Yokohama Bay to Kaena Point, along the coastline and offshore waters. They also scoured the area beyond the shoreline in Mokuleia to the cliffs and in ravines.
