Roman-Martinez’s friends reported him missing two days later on May 23. His phone and wallet were found at the campsite.

Officials now say they are investigating to find someone “responsible for the homicide.”

Monday, Fort Bragg officials said that partial remains were found May 29. The identification of Roman-Martinez was made with dental records, officials said.

“The remains washed up on Shackleford Banks Island, part of the Cape Lookout National Seashore, an area where the prevailing tides have unfortunately washed ashore remains in years past,” U.S. Army Criminal Investigation Command said in a news release Monday.
