Two kitchen employees at a posh resort got in an argument about how silverware should be loaded into the dishwasher.
One stormed out and got a gun, then returned to Marriott's Casa Marina to finish the fight.
"The victim is the head dishwasher. The suspect is the busboy," Detective Sgt. Emilio Yannacone said.
The busboy, Yannacone said, "wasn't putting the flatware into the proper containers to be washed."
After the two argued, Jose Antonio Borrell left the hotel. Forty-five minutes later, he returned _ with a 9mm semiautomatic, Yannacone said.
Borrell shot at his antagonist, Reyes Blas Morales, 37, six times, Yannacone said.
Morales was rushed to the hospital, where he died. Borrell fled but was quickly picked up by Key West police and arrested and charged with first-degree murder.
Borrell arrived from Cuba two years ago on a raft, police said. He had worked at the hotel for just a few months.
He had no record of violence in the United States. "He comes back clean on all the things that we run on him. Of course we don't have any cooperation with Castro so we can't tell what he did in Cuba," Yannacone said.
Borrell said he was arrested in Cuba as a conscientious objector, because he did not want to serve in the military, Yannacone said.
Morales had worked at the Casa Marina, an elegant oceanfront resort built by Henry Flagler for the terminus of the Overseas Railroad, for about a year.
"They said he was the best dishwasher they ever had," Yannacone said.
The argument that led to the shooting astonished detectives _ even Yannacone, who has been an officer for 22 years.
"That's probably the dumbest motive I've ever heard."
