An anthropologist assigned to the project said the bones appeared to be human, which was confirmed by Orange County coroner's officials and police, Bertagna said.
A crime scene has been established as police investigate, he said.
Before the property was a scrap yard, it was the site of homes, Bertagna said.
The bones appeared to have been buried six feet in the ground, he added.
