The Naval Criminal Investigative Service has confirmed its investigators are involved in the search for Erin Corwin.
The pregnant 20-year-old was last seen three weeks ago at her home on the Marine Corps Air Ground Combat Center Twentynine Palms.
Spokesman Ed Buice told The Desert Sun that NCIS is helping the San Bernardino County Sheriff's Department with their probe into Corwin's disappearance:
