BOISE, Idaho (KTVB) -- Saturday will mark the three-month anniversary of DeOrr Kunz Jr.'s disappearance. DeOrr's parents reported the two-year-old missing on July 10th while camping in Lemhi County.

Lemhi County Sheriff Lynn Bowerman says his office, along with other agencies in eastern Idaho, went back to the remote campground just this past weekend for another search. Bowerman is in Boise this week for a missing children training seminar put on by the National Center for Missing and Exploited Children.

Bowerman told KTVB the grid search involved animal feces identification, also known as scat, to help rule out abduction by animal. There were reports bears or mountain lions could have been in the camping area at the time DeOrr disappeared, but Bowerman says those animals bury their prey nearby.

And his search found nothing. However, Bowerman went on to say he is not ruling out the possibility of abduction by person or animal. Bowerman said DeOrr's mother and father met with a sketch artist this last week. DeOrr's parents have said they thought a man was looking strangely at DeOrr at a gas station in Leadore. The artist is drawing a composite sketch of what the man may have looked like. Bowerman hopes to release the sketch soon.
