Cristina Ase Missing: The Unsolved Disappearance of a Vancouver Nurse

Cristina Ase missing since March 26, 2024 — nearly two full years — and the case remains one of the most puzzling and active missing-person investigations in the Pacific Northwest. The 63-year-old Argentinian-born nurse, who lived in Vancouver, Washington and worked in West Linn, Oregon, vanished under highly suspicious circumstances that law enforcement still describes as “far from her normal routine.”

Her family, coworkers, and the FBI continue to seek the public’s help. As of March 2026, Cristina Ase has not been located.

Missing in Washington: The Case of Cristina Ase

Who Is Cristina Ase?

Cristina Ase was born on April 26, 1962 in Argentina. She is 5’8″ tall, weighs approximately 151 pounds, with brown/gray hair and brown eyes. She is listed as White (Hispanic) and speaks fluent Spanish and English. Before moving to the United States in the mid-2000s, she worked as a biochemist in Argentina. In the U.S., she earned a bachelor’s degree in nursing and a doctorate in medical science. At the time of her disappearance, she was a respected nursing director at Rose Linn Care Center in West Linn, Oregon.

Friends and colleagues describe her as kind, dedicated, and professional — someone who was looking forward to a staff training session the very day she vanished.

Timeline of the Disappearance (March 26–27, 2024)

• 6:30 a.m. – Cristina Ase was last seen leaving her home in the 500 block of Southeast 123rd Avenue, Vancouver, Washington.
• 6:34 a.m. – She texted a coworker saying she would be late and wouldn’t arrive until 8:30 a.m., offering no explanation.
• She never arrived at work.
• Her husband, Anibal Diaz, reported her missing the same day after coworkers also raised the alarm.
• March 27, 2024 – Her dark gray 2013 Toyota RAV4 (Washington license plate AQT1726) was found unoccupied near her residence in Vancouver. The vehicle showed signs that appeared inconsistent with normal use, including a possible white powdery residue inside.

Phone records later revealed unusual activity: after leaving home, she drove toward Portland, spent over three hours in a specific residential area near Glenwood Park, then her phone went silent around 10 a.m. It has remained off ever since.

What Makes This Case Suspicious?

Vancouver Police and the FBI have stated from the beginning that Cristina Ase’s disappearance is out of character and suspicious. Court documents from early in the investigation revealed she may have misled family and coworkers about her whereabouts in the days and weeks prior. Despite this, no arrests have been made, and no suspects have been publicly named.

The FBI Seattle Field Office added her to its official wanted/kidnap list, and the case is classified as endangered missing.
