Timothy Joseph Winter was 19 and living in Mankato, Minnesota, when he was last seen on May 21, 1988. He was described as 5 feet 11 inches tall, about 180 pounds, with brown hair and brown eyes.

Timothy was reported missing under unclear circumstances and few details about his disappearance have ever emerged. The case has received little media attention, which his family and friends say has complicated efforts to generate new leads. Authorities continue to list the case on NamUs and the Minnesota Missing Persons Clearinghouse and are asking anyone with information to come forward.

If anyone knew Timothy, saw him around May 21, 1988, or has information about where he might have gone, please share what you know.
