Upon arrival, officers located an adult male victim, who has since been identified as 28-year-old Junior Sosa Fernandez, suffering from multiple gunshot wounds. The victim was transported to a local hospital where he later succumbed to his injuries.
Additional responding officers received a description of the suspect’s vehicle via BPD Operations.
