Youn Malual was found shot once through the head around 3 a.m. Monday in his SUV in the parking lot of his apartment complex.
The Denver Post reported that the husband and father of five fled the civil war in what is now South Sudan six years ago. Investigators have no suspects and no apparent motive for the shooting.
The sheriff's office says Malual's wallet and debit card were not taken and that the shooting doesn't appear to be a botched robbery.
Friends say he was returning home from his job working on buses when he was shot.
