Half of a human jawbone found decades ago has been turned over to Franklin County Coroner Dan Blasdel.
Siblings cleaning out their parents’ home after their deaths turned up the bone in their father’s desk drawer. They turned it over to officials at Sacajawea State Park, who contacted Pasco police.
The bone originally was picked up on one of the Columbia River islands upstream from Sacajawea park in the late ’60s, Blasdel said.
Kathy Taylor, a forensic anthropologist in King County, will study it to determine whether it is a Native American bone, he said.
It appears quite old — more than 75 to 100 years — but there is nothing to suggest it is older, Blasdel said.
The 9,500-year-old skeleton of Kennewick Man was found along the Columbia River in Kennewick. But most human bones that turn up along the river were buried there by tribes in the last few hundred years.
In 2009 boaters found a human jawbone with two teeth on the Columbia River shore north of Richland. It was determined to be 300 to 350 years old and was transferred to a group of tribes with ties to the Tri-City area for reburial.
