NEW YORK (AP) — The New York Police Department says they are working to identify a man who was found dead and tied to a cinder block floating off the docks of a Brooklyn neighborhood over the weekend.

A spokeswoman for the medical examiner's office says the man died of blunt force trauma to the head. The death was ruled a homicide Sunday.

The body was discovered Saturday morning, when a pedestrian noticed the body wrapped in a blue tarp and bobbing on the waves off the nearby docks. The tarp was wrapped up with duct tape and the man's legs were fastened to a cinder block.

Police say the body had some level of decomposition. No one has been charged in the death and the investigation is ongoing.
