A human body was found floating under the Robert F. Kennedy Bridge on Monday and an autopsy revealed that the victim was murdered.
The identity of the decedent remains unclear but officials said that he was a man between 40 and 50 years old and that he was clearly assaulted prior to his death.
His cause of death was blunt force trauma to the face, but the medical examiner also listed drowning as a contributing factor.
The decedent was found at around 11:15 a.m. Monday, wrapped in a blanket and covered in trash bags fastened with tape and ropes.
The man also had injuries consistent with blunt force trauma to his legs especially the right shin area.
His upper-middle back vertebra was fractured and his spine was damaged but officials said that it may have happened following the death.
Authorities are working to identify the man and make an arrest in the case.
