Violence is now suspected as a handcuff key and a puddle of blood were found leading many to believe that the four missing from the charter boat Joe Cool may have been murderedBoston (EON) - Violence is now suspected as a handcuff key and a puddle of blood were found leading many to believe that the four missing from the charter boat Joe Cool may have been murdered.

Two men were charged late Tuesday in connection with the case. They are the only known survivors of the incident which police believe was an act of piracy and murder out on the ocean.

According to reports from the two survivors, hijackers killed the captain, his wife, and two members of the crew one by one tossing them overboard.

Federal charges though state that at least one of the defendants has made false statements.

The handcuff key was found as well as blood on the bow of the fishing boat. The 47-foot boat was found abandoned on Monday 160 miles south of Bimini.

The two men were found in a life raft 12 miles from the empty boat. 36-year-old Kirby Archer was charged with unlawful flight to avoid prosecution on a theft charge. 19-year-old Guillermo Zarabozo is charged with making a false statement to a federal agent.

Archer and Zarabozo chartered the Joe Cool boat on Saturday for a trip to Bimini. They paid $4,000 for the trip, all in $100 bills.

Zarabozo stated that an unknown number of killers hijacked the boat and murdered the crew.

The missing include 27-year-old Captain Jake Branam, 30-year-old wife of the captain Kelley, his half brother Scott Gamble who is 36-years-old, as well as crew member 27-year-old Samuel Kairy.

Assistant U.S. Attorney Michael Gilfarb has asked the two men be jailed until the trial as they both pose a flight risk.
