Mitchell T. Hamilton, 37, disappeared from Kansas City, Missouri on January 2, 1996. After watching a holiday bowl game with his father, he said goodbye and walked out of his residence near Gladstone Boulevard and St. John Avenue wearing a red Chiefs jacket and blue jeans. He gave no reason for leaving and left no clue about his destination.

Family described Hamilton as highly intelligent with talents in mathematics and computers but struggling with low self-esteem, social anxiety and a chemical imbalance that made steady work difficult. He had been living with his brother and helping care for two nephews before he vanished. Authorities have said they do not suspect foul play, and tips that he might have gone to Minnesota or Florida did not yield evidence. His family increasingly believes he may no longer be alive.

If anyone knew Mitchell, his routines, or saw him in early January 1996, can you share what you remember?
