A dead body duct taped in a blue tarp and attached to a cord weighed down by a cinder block was discovered in a Brooklyn marina on Saturday, authorities said.

The unidentified man was located near East 58 Street and Avenue U in Mill Basin at around 11 a.m. yesterday, police said. He was pronounced dead at the scene, and the cause of death is currently being investigated by the New York City Medical Examiner.

There were no obvious signs of trauma, investigators said, and the corpse was not badly decomposed.

According to Mill Basin resident Stephanie Kelso, the wrapped body had been there since at least Friday night. "A friend of mine was on the phone here last night and she was walking and said she noticed a blue tarp floating in the water," Kelso told NBC. "Didn't think anything of it until we hear today."

"I'm surprised, it's very unusual for this area," Kelso added. "Not something we expect."

The investigation into the cause of a death, and who might be responsible, is ongoing.
