A search off the coast of Florida failed in its second day to locate a Charleston man who reportedly jumped overboard a Celebration cruise ship as it returned to port.

According to Coast Guard officials, James Miller, 30, of Charleston, jumped early Sunday from a railing on the Bahamas Cruise Ship Celebration.

The ship was about 27 miles east of Delray Beach, Fla., when the incident occurred. More than 1,100 other passengers were aboard, said Glenn Ryerson, a spokesman for the cruise line.

According to Ryerson, the Coast Guard questioned several people on board before the ship was allowed to return to the Port of Palm Beach.

"The Coast Guard concluded their investigation and there was no question as to what occurred," Ryerson said.

Ryerson would not elaborate on the investigation's findings, deferring further comment to the Coast Guard.

When asked if Miller's disappearance was being treated as a suicide attempt, a Coast Guard official said she couldn't speculate on the situation. The Federal Bureau of Investigation is handling the ongoing investigation, she said.

FBI spokeswoman Denise Taiste did not return an email or phone call on Monday.

Coast Guard crews in Miami received word around 2 a.m. Sunday of Miller's disappearance overboard the traveling cruise ship.

A Coast Guard cutter, two air crews and other teams searched the surrounding area for a person in the water but weren't successful.
