MIAMI -- The FBI has joined the U.S. Coast Guard's investigation into the missing crew of a charter fishing vessel out of Miami Beach.

The 47-foot sportfisher Joe Cool was discovered near the Cay Sal banks, some 100 miles south of its destination in the Bahamas early Sunday evening. On Monday, the two men who chartered the trip were found safe and in good condition about 12 miles from that site on the vessel's life raft.

Guillermo Zarabozo, 19, and Kirby Archer, 35, the two charter clients, are now being questioned aboard a Coast Guard cutter, as two cutters and three aircraft search for the four crew members still missing. The missing crew are Capt. Jake Branam, his wife, Kelly, crew member and half brother Scott Campbell and Capt. Samuel Kairy.

Archer is wanted in Arkansas on charges of stealing more than $92,000 from the Wal-Mart where he worked until he disappeared last January, said Local 10's Glenna Milberg. His picture on a flyer from the Independence County (Ark.) Sheriff's Department was discovered by the boat captain's uncle, who entered Archer's name on Internet search engine Google.

"I don't think the crew ever made it to Bimini. I think the boat did. I don't think they did," said Jeff Branam, who helped his nephew launch the charter boat business after his father died suddenly last year. "I'd like to think they dropped them off somewhere, but I don't know."

Coast Guard agents and family members pieced together the course of events.

The two would-be customers approached the crew of the the sportfisher Joe Cool at slip D-30 Friday evening trying to hire a ride to Bimini, where they said they were to meet their girlfriends. They agreed to pay $4,000 for the trip.

Cousin and co-worker Jon Branam said he noticed that the customers, who said they were construction surveyors, peeled the money off in $20 bills.

"What are they doing with $4,000 in 20s working for a survey company?" he said.

When the charter did not return by its noon Sunday deadline, the family became concerned.

Reported Missing

Jeff Branam reported the vessel and those aboard missing at about 5:45 p.m. Sunday.

Coast Guard agents aboard a search helicopter spotted the vessel about 7 p.m, near the Cay Sal banks Sunday evening, drifting, dragging anchor, and abandoned.

"Everything on the vessel was in complete disarray, thrown around. It looked like whoever had been on the vessel left in a hurry," said U.S. Coast Guard Petty Officer James Judge.

He said a check of the boat's global positioning system indicated the vessel had made erratic movements about halfway to Bimini, then turned sharply south.

There was no sign of blood or violence on the vessel. The life raft was missing.

"I was hoping that if the boat was pirated, they put the crew in the life raft, because it was missing," said Jeff Branam.

Before noon Monday, he learned that was not the case.

Zarabozo and Archer were the only two in the life raft spotted by helicopter Monday morning.

No one answered the door at Zarabozo's Hialeah apartment Monday afternoon. Neighbors told Local 10 he lives with his parents.
