From CNN: “After a short ride on Miami’s elevated Metromover train, a dead shark turned up in the middle of the street, in the middle of the city, in the middle of the night, police said.” The mystery began Sunday when a Metromover passenger took a photo of the shark, bleeding and gasping, as it lay on the floor of the train.

The passenger sent the photo to CNN affiliate WSVN-TV in Miami-Fort Lauderdale.

The shark turned up dead on the street, covered with flies, on Tuesday.

“I have never seen a shark in the middle of the street in Overtown, but nothing surprises me in Miami,” said Jorge Pino of the Florida Fish and Wildlife Conservation Commission, which is conducting the investigation.

Police and wildlife officials said two men, whom they described as vagrants, took the shark on the Metromover after failing to sell it at several fish markets.

David Gil, who works at the Casablanca Fish Market, said the men approached him.

“Two guys pulled up on a bicycle; they were both riding and were dragging the shark,” Gil told CNN. “They said it was like 16 feet and about 600 pounds, but when I went out to take a look at it, it was tiny. I’d say it was about 5 feet and about 75 pounds.”

He added, “They had it on a rope with a stick tied to its tail. They were dragging the shark all over Miami, and they were telling me they were trying to sell it for 10 bucks.”
