A young woman's hit-and-run death in Kunia remains unsolved a month later, and her grieving family is pleading for the driver to turn themselves in.

• Tiana Nagadome, 25, was struck and killed by a vehicle on Kupuohi Street near Polina Place in Kunia in the early morning hours of October 11.
• The driver fled the scene instead of stopping, leaving no arrest and no answers for her family and friends.
• Police released surveillance video of a light-colored van believed to be involved, but the case is still under investigation.
• Friends say speeding is common on that stretch of road, where the limit is 25 mph but drivers often go 35-40 mph on a downhill, wide-open run.
• Family and friends are publicly calling on the driver to come forward, saying it's the only way to get closure.

Outlook: Police have not announced any arrest, and the case stays open while investigators hope the public video release or new tips lead to the driver.
