SAN FRANCISCO, California (CNN) -- The U.S. Coast Guard is suspending its search off the California coast for a distressed 29-foot sailboat that was carrying a couple and two children, and explained the incident is "possibly a hoax," Cmdr. Don Montoro said Tuesday.
The mission's cost has reached hundreds of thousands of dollars since Sunday, he said.
Searchers have been scouring the water off San Francisco for the people distress calls said were on the boat. That included the couple, their 4-year-old child and the child's cousin, who the Coast Guard said was younger than 8.
CNN's Dan Simon reported from San Francisco and Michael Martinez from Los Angeles.
