Oklahoma authorities investigating after man finds human remains in river

POTTAWATOMIE COUNTY, Okla. - Authorities are investigating after a man found human remains along the South Canadian River Thursday.

The sheriff's office says a man was fishing on the river when he discovered a human jaw. He then took the remains to authorities, who tell NewsChannel 4 the Oklahoma Medical Examiner has taken possession of the jaw.

Investigators say it's too early to tell how old the remains are, but it's not uncommon for human remains to wash up on the banks of the river.

“It’s not real uncommon on the rivers that we find human remains. The true test is where they came from," said Undersheriff Travis Palmer.

"They might even be from an old Native American burial site," said  Palmer. "The river’s been up several times in the past five or six years.”

Next, the jaw will be looked at for any signs of DNA and missing persons databases will be searched to see if there is a match.

So far, this isn't being investigated as a homicide.
