The Chatham County Sheriff's Office said the Office of the Chief Medical Examiner used dental records to identify the man as Siddarth Andagudi Prabhushankar, 23, of 4700 West Grove Tower, Raleigh.
The medical examiner concluded the death was a suicide, and the sheriff's office has closed the investigation, according to a statement from Chief Deputy Gary Blankenship.
People fishing off the pier told authorities that they saw a large flame and heard a scream in the upper parking lot at about 10:30 p.m. Sunday. When they went to investigate, they found a man on fire, but they were unable to save him.
Witnesses said they didn't see anybody or any vehicles leaving the area at the time.
