Benjamin Clemens Kalina, 27, was reported missing in February 2007 after he failed to show up for work and a friend could not reach him. A resident of Superior, Colorado, he was last seen there. He is described as a white male, 5 feet 11 inches tall, about 220 pounds, with brown hair and brown eyes.

Authorities learned he had been struggling with his mental health and was considered suicidal. A suicide note was reportedly found in his personal vehicle, and he may have been in possession of a .40 caliber pistol. Kalina had rented a red 2007 Ford Escape from an Avis agency; that rental vehicle was later found abandoned in Arizona, but no definitive answers followed.

His mother, Connie Elstun, has continued to push the case forward, providing DNA and participating in missing-persons events. What possible sightings, tips, or records exist for Ben after the rental Escape was found in Arizona?
