A man was killed at a community festival in Kailua, and police are still piecing together what happened.

• The victim was identified as a 30-year-old Kaneohe man, shot in the neck and killed in a Target parking lot near the festival.
• Police say an argument between two groups at the festival spilled across the street before someone pulled a gun.
• The death has been ruled a homicide, and detectives are asking anyone with photos or video from that night to come forward — even clips that do not show the shooting.
• Festivalgoers standing yards away heard nothing and only learned what happened from posts online.
• Attention is turning to where the guns came from, with Hawaii's existing storage and safety laws already on the books.

Outlook: The investigation hinges on crowd footage and tracing how the weapons were obtained, with renewed debate over gun access likely to follow.
