Arlene Montalvo Piceno Missing Person Case

Arlene Montalvo Piceno, a 57-year-old Hispanic female, was last seen in Los Angeles, California, on July 1, 2018. At the time of her disappearance, she was 5 feet tall and weighed between 150 and 200 pounds. She has black hair and brown eyes. Distinguishing features include tattoos of the name "Ontario Talavarez" on her right forearm and a star on her right middle finger. She may also use the alias Arlene Piceno Baltazar. The official report with the Los Angeles Police Department was not filed until May 24, 2021, under case number 211310148.

The circumstances surrounding her disappearance indicate she was last seen leaving her daughter's home in Los Angeles. Her intended destination was Matehuala, a city in the Mexican state of San Luis Potosí. She had planned to travel by bus to visit a boyfriend known only as "Primo," who was residing in Matehuala after being deported from Memphis, Tennessee. It is unclear if she ever arrived at her destination.

A significant development in the case occurred in 2021 when Arlene called her daughter. During the phone call, she stated that she was in Matehuala, Mexico. However, her daughter has not had any contact with her since that conversation. At the time she went missing, it is believed she was in possession of her U.S. Passport, a Tennessee Driver's License, and a California ID card.

The investigation into Arlene Montalvo Piceno's disappearance is being handled by the Los Angeles Police Department's Adult Missing Persons Unit. Her case is listed in the National Missing and Unidentified Persons System under case number MP154217. As of early 2026, her whereabouts remain unknown, and her case is still considered active.
