Summary based on 3 sources
In the community of Lake Stevens, Washington, a sense of concern lingers over the disappearance of 16-year-old Monica Arroyo, who was last seen on January 29, 2026. A previous missing person report from 2023, when she was 13, described her as being 5' 5" tall and weighing 140 pounds, with brown eyes and black hair. Though this description may not be entirely current, it offers a point of reference for those who may have seen her. The circumstances surrounding her disappearance have left her family and community searching for answers.

Details regarding the specific events leading up to Monica's disappearance remain limited in public reports. It is known that at the time she went missing, authorities believed she might be in the company of a male juvenile. There was also an indication that she might have traveled to the nearby city of Mount Vernon, Washington. This information has led to appeals for the public's assistance in both the Lake Stevens and Mount Vernon areas, as friends, family, and law enforcement hold out hope for her safe return.

The investigation into Monica Arroyo's disappearance is ongoing, with law enforcement agencies encouraging anyone with information to come forward. The Snohomish County Sheriff's Office has been involved in the case, and their contact information, along with that of the National Center for Missing & Exploited Children, has been circulated for those who may have any leads. The case serves as a somber reminder of the many young people who go missing, and the enduring hope of their communities for a resolution that brings them home safely. The lack of significant updates in the months following her disappearance has been difficult for those who know and care for her, as they continue to wait for any news that might lead to her location.
