David Tobias was last seen on November 23rd at the Shop and Save in Latrobe, PA. A search dog tracked his scent to Derry, but the trail was lost near Hillside on Route 217, suggesting he may have been picked up by a vehicle and could now be anywhere. He was last seen wearing a light blue striped knit hat, a dark green plaid flannel, and tan cargo pants. David has a mental health condition and may be in need of assistance.
