Jeffrey Lynn Alexander, 54, was found dead in an alley near downtown Tulsa on the morning of Saturday, October 3, 2015. Tulsa police determined he had been shot and killed the previous day, and investigators linked his slaying to a separate shooting that occurred the same day at a local barbershop.

Police identified James Parker as a person of interest in the barbershop shooting and later connected him to Alexander’s killing. Prosecutors said the motive for Alexander’s murder was robbery. Parker was arrested and charged with first-degree murder and related counts stemming from the barbershop incident; he was later tried and convicted.

If anyone saw activity in the downtown Tulsa alley or the barbershop area around October 2–3, 2015, or has information about Alexander’s last movements, please come forward.
