San Bernardino police are investigating a fatal shooting on the 1200 block of N. Sierra Way after officers and paramedics found an unidentified man with gunshot wounds to the chest and left shoulder around 7 p.m.; he was pronounced dead at the scene. Gang-unit detectives have been assigned to assist homicide investigators, and officials said it was too early to know whether this shooting is related to another incident nearby.

Less than 24 hours earlier on the same block, two men were shot; one of those victims, 21-year-old Adante Whittiker of San Bernardino, died Friday morning and a second man was shot in the leg. Contact information for detectives handling either shooting is provided for anyone with information.

Are there any local witnesses or neighbors who saw activity on N. Sierra Way in the 24 hours around these shootings who can help investigators?
