BOISE-- The Ada County Sheriff's Office has located two people seen in surveillance video before a trail camera used by members of the Boise State University Intermountain Bird Observatory institute was removed from a tree off Idaho 21 in May.

A Boise State employee told detectives that the camera had been secured to a tree branch with a steel cable and was in fine working condition at the end of April, when she did an inspection of the area. The camera was placed at the observation area by Idaho 21 to study mammal populations.

The same employee says she went back to where the camera was placed and discovered that the cable had been cut and the camera was missing on May 4.

After reviewing the camera's video, they found images of two people, possibly teenagers, walking by the camera multiple times between 7:30 p.m. to 8:40 p.m. on May 2. This was around the same time that it was cut down.

The sheriff's office said detectives are continuing to work on the case, and that no charges have been filed.

Officials thanked everyone who contacted them with information about the case.
