Tung Dieu Tran, 24, disappeared after leaving his family home in Goshen, Indiana on September 18, 2003, to visit a friend in Kalamazoo, Michigan. He was last seen in Cooper Township, Michigan and never contacted his family again. His sister reported him missing to the Elkhart County Sheriff’s Department.

Tung is described as an Asian male with black hair, brown eyes, 5 feet 4 inches tall and about 160 pounds, with a labret piercing below his lower lip. A black 2003 Honda Civic he was driving was later found in Allegan County, Michigan; the vehicle was being driven by the friend he had planned to visit, and investigators began treating the case as involving possible foul play. Michigan State Police and the Elkhart County Sheriff’s Department have been involved in the inquiry.

What information might help clarify where Tung went after he reached Michigan or explain why his car ended up with his friend?
