We have lost contact with our son, Jake Thompson, who is 22 years old. He was last seen around downtown South Bend on Wednesday afternoon and was wearing a grey hoodie and jeans. He has short brown hair and was carrying a black backpack. We are really worried and would appreciate any help in finding him.
