This month marks the two-year anniversary of the disappearance of a pregnant Loudoun County woman who had both a husband and a boyfriend.

Bethany Anne Decker, then 21, was last seen at an apartment on Orchard Grass Terrace in Ashburn on Jan. 29, 2011.

Decker was married but was having an affair. Her husband, Emile Decker, last saw her that morning and left for Afghanistan with his Army National Guard unit a few days later. Her boyfriend, Ronald Roldan, might have been the last person to see her.

Detectives have questioned both Decker's husband and her boyfriend during their investigation. Authorities do not know which man fathered the child that Decker was carrying.

Decker was registered as a student at George Mason University, but had not attended classes since. There also has been no activity on bank accounts, cellphones or email. Her car was left behind in the parking lot of her apartment, according to the Loudoun County Sheriff's Office.

Decker has been described as white, 4 feet 11 inches tall and 130 pounds. She has brown hair and brown eyes.

In November, Decker's case was featured on the Investigation Discovery television series called "Disappeared."
