UPDATE: Authorities have identified the body found at Lake Overholser over the weekend as 22-year-old Karn Natalia De Leon of Oklahoma City.
Her mother had reported her missing April 6.
OKLAHOMA CITY - Oklahoma City police continue to investigate a disturbing discovery near Lake Overholser Saturday morning.
Volunteers picking up trash stumbled upon a body near N.W. 63rd and Morgan Road, an area around the Stinchcomb Wildlife Refuge.
Bill Gronos was one of the volunteers out there Saturday morning as part of a special Earth Day clean up with a group known as the Friends of Lake Overholser.
He had identified the area ahead of the clean up.
"I found a big dump of tires and I found appliances had been dumped there. So she sent a team out where they don't normally go," Gronos said.
Gronos said the team sent to this area came back earlier than the other teams.
Gronos was working the registration table that day.
"They go, 'Cops kicked us out of there,'" Gronos said. "We found a human body and we called 911. The police came and they declared it a crime scene and they said you've got to leave."
Gronos said he actually wasn't surprised and can't believe in all his walks off the beaten path at Overholser that he hasn't made a similar gruesome discovery.
"I can't believe I haven't stumbled upon one already; it would be the perfect place to get rid of a body," he said.
Gronos doesn't know the woman who personally found the body but said he heard it was very difficult for her.
"The word I got was that it was pretty upsetting to her to say the least," Gronos.
Police have not even released whether the body is that of a male or female.
Officials said they won't know if a crime was actually committed until the medical examiner determines a cause of death.
Gronos hopes investigators get to the bottom of what happened.
"Somebody who didn't know where a family member went, this is important to somebody," Gronos said.
