Cristina Ase, 62, a nurse and native of Argentina, was last seen at her Vancouver, Washington, home on the morning of March 26, 2024. She texted a coworker at 6:34 a.m. saying she would be an hour late for an 8:30 a.m. training but never arrived. Her husband and coworkers reported her missing the same day after she failed to show.

On March 27 her dark gray 2013 Toyota RAV4 was found parked near her apartment in Vancouver. Investigators reported a powdery residue on several surfaces inside the vehicle that they believed could be a cleaning agent. Phone data show she left home around 6:34 a.m., traveled into Portland, spent hours near Glenwood Park, and the last ping came near Southeast Flavel Street and Southeast 92nd Avenue before her phone was turned off. The disappearance is being treated as suspicious and the FBI has joined the investigation.

Anyone who saw Cristina or her vehicle near her home or the Portland locations where her phone pinged is asked to come forward with information or video.
