(9:45 a.m. EDT) -- A search is underway for a 67-year-old female cruise passenger who has been reported missing from Princess Cruises' Sapphire Princess.
The ship arrived back in Vancouver yesterday after a four-day cruise to Alaska, which included a call in Ketchikan on Monday. Princess has confirmed that staff became aware that the woman was missing after she didn't disembark the ship on Wednesday. Crew went to the cabin and found her belongings, but there was no sign of her.
The U.S Coast Guard launched a search yesterday using a helicopter, aircraft and boat from Ketchikan.
The U.S. authorities are searching an area from Ketchikan to Canada that spans 86 miles, while the Canadian rescue teams are searching an area from Vancouver north to Hecate Strait.
