An extensive search for a missing la pine man Wednesday turned up nothing. And authorities say they can't rule out "foul play." Dean Marsh, 58, has been missing since Saturday and family members say it’s not like him to just disappear. About a dozen search and rescue crews spent much of Wednesday searching the area on the ground and in the air. An airplane looked near the snowline in case Dean Marsh got stuck somewhere,but so far, no leads. Captain Marc Mills with Deschutes County says they are also contacting agencies in Washington and California." The family is adamant that it is very uncharacteristic of Mr. March to not be in contact with them, or a friend. Which leads us to continue to be as diligent as we can about attempting to locate him. We can’t rule out foul play, ‘cue we have nothing indicating actually one way or the other. We certainly would like to, but at this point, we are unable to do that.” They are watching his credit cards and bank accounts for any activity. Mills says they believe he did gas up at his regular La Pine gas station. The station does not have cameras and the attendant couldn't say for sure if Marsh was there Saturday afternoon.
