Authorities have conducted numerous searches and dozens of interviews in their investigation into the disappearance of a 21-year-old pregnant Ashburn woman, the Loudoun County Sheriff's Office said Wednesday, but they say they have yet to find signs of foul play.

Bethany Anne Decker has been missing since Jan. 29.

Decker’s husband, Emile Decker, was returned to the United States from a deployment with the U.S. Army National Guard in Afghanistan, authorities said; he has cooperated with the investigation.

A man described in court documents as Decker's boyfriend and the father of her unborn child has also been cooperating, the Sheriff's Office said. He is believed to be the last person to see Decker at her Ashburn apartment.
Investigators say they will continue to search the area near Decker's apartment. They are also examining cell phones and computers obtained with search warrants following reports that someone claiming to be Decker had used her Facebook page after she was reported missing.
Decker, a student at George Mason University who is believed to be 5 or 6 months pregnant, was reported missing by family members on Feb. 19. Her cell phone, bank accounts and credit cards have not been used since Jan. 29, investigators said.
