Port Orford police are investigating the discovery of human bones after a man found a skull under a trailer he was moving from a trailer park Monday afternoon.

The bones were discovered when the new owners of the Anchor Inn RV Park, at 557 9th St., were removing an abandoned trailer. The skull was laying on the ground; other bones were found buried later.

"I don't think it's an Indian burial ground," Craig Lundborg, the new owner of the park, said with a laugh. "That's the good news."

Lundborg purchased the trailer park 13 months ago and was rehabilitating the 10-site park when he found the skull and called police. Other bones were found in the area Tuesday.

It was not known as of press time who the former owners of the trailer were, although it had been abandoned for about a year, Lundborg said. He originally planned to tear it down, but upon moving it, he found the skull. Lundborg added that he's "pretty positive" the bones had been abandoned there within the past five years.

Oregon State Police Forensic Team members started digging into the ground Tuesday morning in search of more clues. If more bones are found, forensics experts might be able to identify the person and determine the cause of death.

Police Chief Marvin Combs declined to label it a crime scene as they have just opened the investigation.

"Right now, it's just a death investigation," he said. "We don't know if the skull is here because of a crime, or if any foul play was involved at all."

The trailer was removed Monday and will be investigated for clues. Police stayed on scene to protect the area overnight for crime scene investigators."We just don't know yet," Lundborg said. "They're trying to put some semblance of order to the evidence. What we think one hour is different the next hour. We'll just let Chief Combs and the boys do their job."

State police Lt. Steve Smartt said more information might be available later this week.

It is the second time this year bones have been discovered in Curry County. The first set, a full skeleton, was found by construction crews on a brush-covered embankment just south of the Pistol River Jan. 9.

"There many different scenarios,"OSP Sgt. Andrew Kenyon said of the Pistol River body. "It could be one of many transients that travel the highway, perhaps someone who died of exposure; or it could have been the victim of a hit and run."

Officials are still working to learn the identity of that body, which was transported to the OSP crime lab for DNA and dental examination.
