Homicide investigators said they believe that the victim, identified as 56-year-old Duane Lee Murley, went to the ATM at the bank and was then confronted by one or more suspects. The victim was shot in his truck, which traveled a short distance and came to rest in the parking lot. Murley was pronounced dead at the scene.
Wells Fargo offered a $25,000 reward for information leading to the arrest and conviction of whoever is responsible for the crime.
