The medical examiner's office has determined two of the bones found at the North Park roundabout last week belonged to pigs, not humans as previously suspected.
Andrew Preeper, a spokesperson for the Department of Justice, said they're still waiting on results of testing from the third bone.
The tests are expected to be done next week.
Construction workers made the surprising discovery on Aug. 7 while ripping up the street to build a new roundabout.
The bones were found where a Protestant orphanage stood in the late 1800s.
