Some construction workers in Volusia County dug up more than dirt recently.

They found a human skull.

Considering the site's history, investigators think the workers have found an old burial ground at Florida Hospital DeLand, located on Plymouth Avenue.

According to records, the area was the site of a 1920s burial ground where people of unknown identity were placed.

The skull was found about 10 feet below the surface.

Offices with the DeLand Police Department will continue to investigate the area.
