Darrell Louis Steinback, a 69-year-old Caucasian man who worked as a Yellow Cab driver in Nashville, Tennessee, was killed on February 23, 2011. No arrests or publicly identified suspects have been reported, and the investigation appears to have gone cold. Steinback is survived by a daughter, a grandson, and sisters who were left without answers about why he was taken.

Are there readers who remember seeing Darrell, knew his passengers or coworkers, or have any information that could help shed light on what happened that day?
