Sean Daniel Winegar, 45, was found shot to death in an alley on the 600 block of West in San Bernardino on the morning of August 5, 2012. He was pronounced dead at the scene after San Bernardino police responded to reports of gunfire.

Winegar lived in Corona and had a prior arrest history, including an arrest on warrants or holds in Riverside County in December 2005, but there is no clear link between those past incidents and the circumstances of his killing. Investigators have not publicly identified a motive or a suspect, and the case remains unsolved amid broader challenges with shootings and homicides in the area.

Anyone with information about Winegar’s movements that night or the shooting is asked to contact San Bernardino authorities.
