The FBI's Seattle Field Office is working with the Des Moines Police Department in Washington, the United States Government, and Mexican authorities to conduct a formal investigation into the disappearance of Shelbie Lynn Dwyer.  On March 25, 2023, Dwyer voluntarily left the Des Moines, Washington, area and traveled to Mexico via car.  Dwyer maintained sporadic communication with her family, but stopped that communication around March 29, 2023.  Dwyer is believed to have traveled to Tijuana, Mexico. She likely traveled by plane from Tijuana, had a layover in Guadalajara, then arrived in Culiacan, Sinaloa.  Dwyer was last believed to have been in the area of Guamuchil, Sinaloa, Mexico, on or around March 29, 2023. She has not been heard from since that time.
