HONOLULU (AP) - The U.S. Coast Guard is suspending its search for a crew member from a vessel carrying cars from Japan to Hawaii who went missing after the ship caught fire.
  
The Coast Guard made the decision to suspend the search for the Serenity Ace crew member on Wednesday.
  
Sixteen crew members were rescued from the vessel. Four other crew members were listed as unresponsive after rescue ships spotted them and lowered life rings but got no reply.
  
The U.S. Coast Guard coordinated with merchant ships on the rescue effort.
  
Japanese shipping company Shoei Kisen Kaisha Ltd. owns the Panamanian-flagged vessel.
  
The cause of the fire was unknown.
