Gregory Lamont Smart, known as Greg or Tupa, was 27 when he disappeared from Clayton, Missouri, in the autumn of 1999. Last seen in November of that year, reports do not give an exact date. He was wearing tan pants and a green shirt at the time he vanished.

Gregory is described as six feet tall, about 230 pounds, with short black hair, brown eyes, a scar on his right cheek and a scar on a finger of his right hand. He had multiple tattoos, including one on his upper left arm. The Saint Louis County Police Department is handling the case; Gregory’s mother provided a DNA sample that has been processed and is being compared with national databases.

The circumstances of that day remain unclear and the family continues to seek answers. If anyone knew Gregory, his routines, or saw him in Clayton in November 1999, please share what you know.
