Gangs of Little Havana/Execution in Coconut Grove

S1, E1: In this opening episode of The First 48 homicide investigators attempt to solve two murders where the killers brutally pulled the trigger at point-blank range. In "Gangs of Little Havana," the team find a young man lying dead on the sidewalk in an area noted for gangland violence. From the outset this appears to be the latest tragic result of a turf war between two gangs. The investigating team is hampered by a wall of silence from a frightened community. But hour by hour the full story of what really happened begins to emerge. In "Execution in Coconut Grove," a convenience store owner appears to have invited someone she knows into her home before being savagely shot twice in the head. The detectives quickly discover that she also sold jewelry, and a ransacked room suggests that this could be a robbery that went wrong. Or is this what the murderer hoped they would think? With no obvious suspects a major forensic operation gets underway with the house examined inch by inch for fingerprints, which could put a name and face to the killer.
