ASHBURN, Va. (WUSA) -- Loudoun County Sheriff's Office authorities say they have not found any evidence of foul play at the home of a missing Ashburn woman.
Bethany Anne Decker, a 21-year-old mother who is expecting another baby, was last seen on January 29th. She was reported missing February 19th by her family and authorities have been trying to locate her ever since.
The Loudoun County Sheriff's Office authorities say they conducted dozens of interviews and gotten more leads.
But on Thursday, Sheriff Steve Simpson indicated the lead they believe will help them solve the case may be closely guarded by one of the many people they've interviewed.
"Some are cooperative, some are not," he said. "We feel we've probably interviewed folks in this investigation that probably have information we'd like to have but have been reluctant to hand that information over yet."
Authorities say they have interviewed her husband Emile Decker, who is a member of the National Guard. They say he was with his military unit in Afghanistan and last saw his wife in the early hours of January 29th while on leave. They say he returned to Afghanistan on February 2nd. Authorities say Emile Decker was brought home and is fully cooperating with them.
Authorities say they have also talked to Ronald Roldan, who was living with Mrs. Decker and is believed to be the last person to see her at her Ashburn apartment later on January 29th.
Her other family members and friends have been interviewed, say authorities.
Several searches near Mrs. Decker's apartment in Ashburn, including by helicopter, have not pointed to evidence of foul play, but authorities still spent all day Thursday exhaustively searching a large undeveloped stretch of land across from where she lived off of Loudoun County Parkway.
"If there is foul play we like to check all the areas where you might find evidence of foul play," said Simpson.
Investigators have search warrants for items such as cell phones and computers. Authorities say a forensic examination of the items is being conducted and they are awaiting the results.
Also, someone claiming to be Bethany Decker is believed to have been using her Facebook page after she was reported missing and after a prolonged period of inactivity, say authorities.
According to authorities, Bethany Decker's car was left behind in the parking lot of her apartment and has been secured by the Sheriff's Office. Her apartment was also searched.
Authorities say they know Bethany Decker did not leave the country. They also say there has been no activity on her bank accounts, cell phones or e-mail.
She was registered as a student at George Mason University but has not attended any classes since she was reported missing.
Decker is believed to be approximately five to six months pregnant.
