CALAVERAS COUNTY, Calif. — The large scale efforts that had 100 people searching for missing journalist David Johnson were suspended by the Calaveras County Sheriff's Office.
The search efforts had been focused on the Mokelumne River Canyon between the Electra Hydro Power Plant and the Pardee Reservoir.
Before Saturday's search, authorities said the reservoir had been searched with boats and specially trained dogs. A part of Highway 49 was also reduced to one lane during to make sure the road and embankment searches were thorough.
Deputies believe a "selfie" photo, which was taken near a small creek that flows into the Mokelumne River and sent to a friend, was Johnson's last known contact. K9's indicated that Johnson's scent went from the location of the photo toward the river's edge.
Authorities also found clothes and motorcycle riding gear between the location of the photo and the river's edge. A wallet, electronics, and a camera that belonged to Johnson were also found in the area.
Deputies had been searching daily for Johnson since his motorcycle was found at Big Bar River in working condition and with keys in the ignition on June 7.
Over 448 miles were searched on foot, which doesn't include the distance searched by those in the air or searching by boat.
Resources from multiple agencies were used in the effort to find Johnson, and, while the search will continue, it will be the focus of the sheriff's Marine Safety Unit and sheriff's detectives.
Those with information of David Johnson's disappearance are asked to call the Calaveras County Sheriff's Office at 209-754-6500 or the Investigations Tip Line at 209-754-6030.
