RENTON, Wash. - Officials say human bones discovered at a Renton home construction site are likely the remains of someone who was buried in the early 1900s.

Police spokeswoman Penny Bartley said officers originally were investigating the discovery as a crime scene, but that has now been ruled out.

Investigators found a jaw bone, teeth, vertebrae and fragments of other human bones at the site. Police believe the bones came from one body, because no duplicates have been found.

Multiple metal pieces that appeared to be parts of a coffin also were found buried in the same area.

Officials don't believe the human remains are tribal, because there is no record or evidence of any Native American settlements in the area.

A developer purchased the land at 2211 Edmonds Ave. NE a year ago and the original house was demolished for new home construction.

Crews first uncovered a jaw bone on Thursday while digging a ditch. Investigators with the King County medical examiner's office turned up more bones Thursday.

Police and medical experts now have determined that the bones were most likely buried by a family who lived at that site in the early 1900s.

Prior to 1943, it was legal to bury family members on private property. After that, a law was passed requiring all burials to be in cemeteries.
