Andrew Lewellen, 42, of Altoona, Kansas, was last seen on May 9, 2011. He is described as 6 feet tall, 165 pounds, with blond or strawberry hair and blue eyes. His disappearance is sudden and remains unresolved; few details have emerged about his movements after that May day.

Months before he vanished, Lewellen was involved in a police chase near Humboldt, Kansas, in August 2010 and was arrested for obstruction. That incident is noted in timelines of his life and has prompted questions about his circumstances in the period leading up to his disappearance. The Kansas Bureau of Investigation currently lists him as an active missing person case and continues to seek tips.

If anyone knew Andrew, his routines, or was in the Altoona or Humboldt area in the spring of 2011, please share what you remember with investigators.
