Arianna Duenas Romo was 17 when she was last seen on December 19, 2025, in Phoenix, Arizona. Family and authorities launched an urgent search after she failed to return and there was no word on her whereabouts in the weeks and months that followed.

Arianna is described as a White or Hispanic female with brown eyes and uniquely dyed hair in three colors: maroon, black, and blonde. Investigators were told she might be using the alias Debbie Macdonald, a detail that could affect where she might be found or who has seen her.

Anyone with information about Arianna’s movements, sightings, or the use of the alias Debbie Macdonald is asked to contact the Phoenix Police Department. Did anyone in the Phoenix area see a teenager matching this description after December 19, 2025?
