Luis Pena was 64 when he was found dead in his trucking company’s office trailer in Chicago on December 30, 2016. Responding officers initially believed he’d been shot, but an autopsy later confirmed Pena had been both stabbed and beaten to death.

Surveillance footage from the scene identified a former employee, Justin Payne, as a suspect. Payne had worked for Pena only briefly and was fired for poor performance. Nearly a year after the killing, Payne was located in New Orleans when he attempted to join the local police force; the recruitment process led to his identification as a suspect, a warrant was issued after a confession, and he was arrested there. Pena’s family said the arrest brought relief after months of dwindling hope.

Does anyone have additional details about Pena’s life or the company that might help fill in what happened leading up to December 30, 2016?
