WASHINGTON — Police searching a wooded area of Prince William County, Virginia for a teen boy who disappeared last month found human remains Tuesday, authorities said.

Prince William County were preparing to conduct a search for missing 16-year-old Palmer Marsh near Lake Manassas in Nokesville, Virginia, when investigators happened upon the decomposed remains, police spokesman Nathan Probus told WTOP.

The FBI was also assisting with the search.

Investigators are waiting on the medical examiner to confirm the identity of the remains.

However, investigators say the remains were found only a 10-minute drive from Marsh’s parents’ house in Nokesville.

Marsh has been missing for more than a month.

Police said the teen voluntarily left home May 2 after an argument with his parents. Two days later, his family reported him missing, police said.

Probus said police have done multiple land and air searches for the boy since he was classified as an endangered missing person May 24.

Police expect to hear from the medical examiner this week.
