The Coast Guard is suspending its search for two Florida Keys boaters and their dog who have been missing for a week.

The branch's Southeast district named the missing couple, saying Omar Millet and Betsy Morales were last seen near Wisteria Island.

Millet contacted Coast Guard Sector Key West Command Center watchstanders at 11 p.m. ET on Sept. 27, reporting that his vessel's anchor line had broken and that the vessel was adrift.

Due to Hurricane Ian, the sector was unable to immediately launch rescue assets and crews, but provided emergency instructions and established a communication schedule.

At approximately 1:30 a.m. ET on Sept. 28, Sector Key West Command Center watchstanders were unable to make contact with the pair, and Coast Guard air and surface assets were launched to begin search efforts.

Crews and partner agencies searched more than 15,171 square miles for the vessel amid hurricane conditions – an area larger than the state of Maryland. 

The agencies deployed included the U.S. Navy, the Monroe County Sheriff's Office, the Florida Fish and Wildlife Conservation Commission, as well as the Coast Guard Station for Key West and the Coast Guard Air Stations for Miami and Clearwater.
