Authorities say they have notified the family of a missing Everett man after a body was found in a black Jeep recovered late Friday off a logging road in a remote area of Linn County, Ore. Police say they are waiting to confirm if the body belongs to a man whose wife was slain in the couple's Washington home on Sept. 28.

Reports are that the vehicle is owned by David Jones Pedersen who is affectionately known to family and friends as Red. Pederson has been missing since September, the same month his wife Leslie Pedersen was found stabbed to death in their Everett  home.

Everett Police Sgt. Robert Goetz told The Seattle Times that officials are waiting for the results of an autopsy and positive identification before they determine whether the body belongs to David Jones Pederson. An autopsy is tentatively scheduled for Monday and it should shed light on how the man died, authorities said on Saturday.

Police arrested David Joseph Pedersen, 31, the missing man's son, in Yuba City on Wednesday in connection with his stepmother's killing. His 24-year-old girlfriend Holly Grigsby has also been implicated in what an Oregon county sheriff's captain has said is vicious, vile reign of terror, according to The Associated Press.

The Seattle Times also reported that the son has also been arrested in connection with the death of a 19-year-old Oregon man, as authorities found him and his girlfriend driving the 19-year-old's car when they were stopped by California police. Pedersen has reportedly served more than 13 years in prison for robbery and assaulting a police officer, according to The Seattle Times. They both are still in custody in California on weapons and auto-theft charges. They haven't been charged in the Oregon and Washington killings.

That report also stated that three firearms were found in the car that belonged to Cody Myers. Myers was last seen leaving his Willamette Valley home to go to a jazz festival on the Oregon Coast the same weekend Leslie Pederson was found dead.

It was tip that led search-amd rescue workers to the remote forested mountains southeast of Salem, Ore. where they found the Jeep resting at the bottom of a steep embankment beneath the logging road. It was near a campground in the Cascade Range that's open only in the summer, according to The AP, which also said the difficult terrain caused rescue workers to struggle to recover the body.

It took some time to come up with a plan to bring the vehicle up to a place where investigators could safely see inside, Everett Police Sgt. Robert Goetz told The AP. Police are still unsure if the body was injured before the Jeep went over the embankment.
