In the Sumner County community of Portland, Tennessee, a family's life was disrupted by the sudden disappearance of 18-year-old Alicia Beatriz Diego Sebastian on May 27, 2025. A young Hispanic female with black hair and brown eyes, Alicia stands between 4 feet 8 inches and 5 feet 5 inches tall, weighing approximately 130 to 140 pounds. The circumstances of her departure are troubling; her family reported that she left their home in the middle of the night, taking all of her belongings with her. This detail suggests she may have planned to leave, but her destination and reasons remain a mystery. Compounding the difficulty for those searching for her, there was no description available of the clothing she was wearing when she was last seen.

The Portland Police Department opened an investigation into Alicia's disappearance, registering her as a missing person. The case, assigned the number 25-01425, has left local authorities and community members concerned as they seek to determine her whereabouts. Information about her case was also entered into the National Missing and Unidentified Persons System to broaden the reach of the search. The lack of specific leads or public disclosures about potential foul play or voluntary absence means that investigators must consider all possibilities. The public has been urged to stay watchful and to report any information, no matter how insignificant it may seem, that could help locate her.

The overall picture of Alicia Sebastian's case is one of perplexing ambiguity. An 18-year-old woman vanishes from her home during the night, taking her possessions but leaving no word of her plans or her current well-being. This lack of communication is the central cause for concern for her family and law enforcement. The investigation remains active, with authorities hoping for a breakthrough that will provide answers. The search for Alicia represents a collaborative effort between her family, the Portland Police Department, and the wider community, all holding out hope for her safe return as they continue to share her story and seek information that might lead to resolving this distressing case.
