Hailey Elizabeth Kupihea was 17 when she disappeared from her grandmother’s home in Phoenix on July 28, 2025. Family members and investigators raised particular concern because Hailey spent a lot of time online and authorities said she may have left to meet someone, though that possibility was presented as unconfirmed. Her family expressed worry that she might need medical assistance.

At the time she vanished Hailey was described as about 5 feet 4 inches tall, 120 pounds, with blue eyes and ear-length brown hair. She had nose and ear piercings, and was known to wear a black choker necklace. No confirmed vehicle, companion, or destination has been publicly identified, and reports do not specify what she was wearing when she left.

The Phoenix Police Department is the investigating agency; the National Center for Missing & Exploited Children circulated her poster and asked anyone with information to call 1-800-THE-LOST or Phoenix police at 602-262-6151. If anyone communicated with Hailey online, knew of plans she discussed, or saw her around July 28, please come forward with what was seen or known.
