Missing person: teenage girl in blue jacket

I lost my 15-year-old sister, Lily Park, yesterday around 3pm in South Coast. She's about 5'1", with long black hair, wearing a bright blue down jacket over a gray hoodie, black leggings, and pink sneakers. Last seen near Seaside Pier by the fish market on Main Street, heading toward Oceanview Park. She wears a silver crescent pendant necklace and carries a small star-pattern backpack with a unicorn keychain—easy to spot. This is really scary; she has sentimental value to our family, and I’m terrified something happened to her. If you know anything or see her, please email me at [email protected].
