OKLAHOMA CITY, Oklahoma - Police say bones found on a construction site in Oklahoma City are human.

The medical examiner is now investigating how the person died and how long the bones may have been there. The workers said they thought the bones were from an animal, but they weren’t sure.

"I’m not savvy enough to know if it is or isn't, a large animal or human, so I went to the police department," said Rob Williams.

A homeless person approached police while they were investigating and said he may know the identity of the body. Officers have questioned two other people.
