John "Jack" Stein was last seen on July 13, 2021 at his home around 7:45 p.m. in the 3700 block of Kanan Road in the Agoura Hills area of L.A. County in California. He suffers from depression and bipolar and may have been in distress. He didn’t have a phone or ID with him when he disappeared, but he could possibly be hitchhiking to his home state of Minnesota or Denver, Colorado or Salt Lake City, Utah - where he has friends. He has blue eyes, strawberry-blond hair, a tattoo of a sparrow on his upper right thigh and circle tattoos on his chest. He was last seen wearing a navy blue hooded sweatshirt with “Tommy Hilfiger” down the arm, black shorts, and gray Nike running shoes.
