Summary based on 8 sources
On May 5, 2001, 22-year-old Rebecca Arellanosa was last seen in the 10700 block of Lawler Street in Los Angeles, California. Authorities have stated that she vanished under "unusual circumstances," a detail that has been consistently associated with her case, though specifics regarding these circumstances are not publicly available. Her case is classified as an endangered missing person, and she has not been heard from since her disappearance. At the time she went missing, her physical and mental condition was described as good.

Of Filipino descent, Rebecca Arellanosa, who was also known by the nicknames Becky or Monica, is described as having an olive complexion, short, straight black hair, and brown eyes. She has a mole near her right eye and another on her left cheek. At the time of her disappearance, she stood at 5 feet 3 inches tall and weighed approximately 120 pounds. The clothing she was wearing on the day she went missing is unknown.

The Los Angeles Police Department is the investigating agency for Arellanosa's case. Despite the passage of time, her case remains unsolved. Publicly available information regarding the investigation, including any potential leads or persons of interest, is limited. The official missing person reports emphasize the "unusual circumstances" of her disappearance, leaving many questions unanswered.

Over the years, information about Rebecca Arellanosa's case has been shared through various online databases for missing persons, including the Charley Project and the Doe Network. These platforms serve to keep her memory and case in the public eye in the hope that new information may surface. The lack of significant media coverage over the years has made it challenging to piece together a more detailed narrative of the events leading up to her disappearance. Her case is a long-standing cold case, and authorities continue to seek any information that may lead to a breakthrough.
