Robert Perry Bissell, 57, left on a solo camping and fishing trip from Portland on July 12, 2010, into the Roaring River Wilderness Area above Estacada. He filed a wilderness-use permit showing an expected return of July 16, drove a white 1989 Nissan Sentra to Trailhead 700, and hiked about five miles to a campsite off Trail 512 near Middle Rock Lake.

At the campsite his sleeping bag and most gear remained, while his fishing rod and tackle were missing, suggesting a short outing to fish. Fellow campers reported seeing and speaking with him early in the trip. When he failed to return, his brother Michael checked the site on July 19 and July 24, then reported him missing. A large search by the Clackamas County Sheriff’s Office began July 25 and at times involved up to 70 people covering more than 100 square miles with ground crews, dogs and air support, but no trace of Bissell was found. Several items turned up that his brother did not identify as theirs. The search was suspended because of the lack of leads and hazardous terrain.

Did anyone in the area around Rock Lakes in mid July 2010 see Robert Bissell or his white 1989 Nissan Sentra?
