Serafin Martinez was 40 and living in Knoxville, Tennessee, when he disappeared after planning to take a Greyhound bus to Chicago. The last confirmed contact was August 1, 2007; he never arrived in Chicago and never made further contact with family.

Serafin is described as Hispanic/Latino and White/Caucasian, with brown curly hair, brown eyes, a mustache at the time he vanished, and he was missing a toe on one foot. The case has remained open and cold, and his family continues to seek answers.

Does anyone have information about Serafin’s movements in Knoxville around August 1, 2007, or recall seeing him boarding a bus that day?
