Overview: In broad daylight, a young man is shot dead in his own front yard. Investigators Gary Galetta and Glenn Weather question witnesses who saw the murder, but no one can identify a suspect. A store clerk appears to have knowledge of the shooting before it happened--could he be the killer? The team uncovers evidence the victim may have been selling loose cigarettes in the neighborhood, but that does not seem like enough of a motive for a murder. It will take ballistic analysis and a careful review of leads--from cell records to surveillance tape--to lead investigators to the killer.
