A 15-year-old boy is in custody over a shooting in Halawa last week, a step forward for police and the neighborhood.

• The teen was arrested on suspicion of attempted murder.
• The shooting happened a week ago in a Halawa housing area.
• Detectives built the case from witness interviews and surveillance footage.
• The arrest came overnight, closing the most urgent part of the investigation.

Outlook: The case now moves to prosecutors, who will decide how to charge a minor accused of attempted murder.
