Samuel Rosiles, 31, was shot and killed in Fresno, California, on January 1, 2015. His death was the city’s first recorded homicide of that year and was described as a violent, suspected gang-related killing that reflected wider patterns of gang violence in the region.

The Fresno Police Department opened an investigation that focused on disputes tied to gang affiliations, but investigators faced challenges common to gang-related cases, including reluctant witnesses and limited evidence. In the weeks after the killing there were few leads, and progress remained slow despite appeals to the public and calls for greater community engagement.

Does anyone who knew Samuel or was in the area that day have information that could help the investigation?
