Dateline: Who was Bethany Decker and what happened to her? Disturbing details of the 2011 case, revealed 

The case of Bethany Decker appeared on Dateline and never really left the public’s mind. Maybe because she was only 21, still a student at George Mason University, trying to balance classes and a full-time job while raising a toddler, already pregnant with her second child. Her life seemed messy but ordinary in its own way, until January 2011 came and everything shifted, because one moment she was in Ashburn, Virginia, and the next she was simply gone.

Her disappearance was not seen as a homicide right away. At first, it looked like a confusing puzzle. A car left behind, odd messages on social media, and a silence that stretched for weeks. Years later, Dateline pieced together the scattered details that exposed the darker truth.

The disappearance in 2011

Bethany was last seen on January 29, 2011. Her car was later found in the parking lot of her apartment complex. Reports described it as parked awkwardly, with a flat tire and dust on the hood. Soon after, messages appeared from her Facebook account. They said she needed time alone and could not say where she was. Friends and family noticed the tone felt wrong, and by mid-February, her disappearance was reported.

Messages and digital traces

The Facebook posts became a focus of the investigation. Detective Mark Bush told Dateline the messages repeated the same idea: Bethany had failed, Ronald Roldan was the best part of her life, and she needed space. Investigators later confirmed the posts were sent from Roldan’s laptop. IP records tied them to the same device used for his own accounts, creating a direct link.

Ronald Roldan and the 2022 confession

For years, no charges were filed. That changed in 2020, when Roldan was finishing a sentence in North Carolina for another assault. Virginia authorities issued a warrant.

In November 2022, Roldan accepted a plea deal. He admitted to second-degree murder and gave a four-hour interview. He said there was an argument, that he pushed Bethany, she fell, hit her head, and stopped breathing. He described placing her body in a Christmas tree bag and dumping it in a trash compactor.

A contested version

Investigators doubted this story. Bush said there were no marks on the window ledge that supported the claim. He suggested strangulation was more likely. The detail with which Roldan described the disposal contrasted with his vague account of the fall. Bethany’s body has never been found.

A violent history

Roldan’s past made the case even more troubling. In 2014, while living with Vickey Willoughby, he attacked her. She shot him in self-defense, but he managed to shoot her in the face. She survived but lost an eye. In 2016, he pleaded guilty to felony assault and went to prison. Authorities later pointed to this as proof of a pattern of abuse.

The family’s reaction on Dateline

Bethany’s mother, Kim Nelson, told Dateline she did not believe the accident story. She called the confession painful to hear. Nelson explained that the family had already sought help from hotlines for Bethany, fearing the relationship with Roldan.

Shortly before she vanished, Bethany traveled to Hawaii with her husband, Emile Decker, who was serving in the National Guard. Media reports noted the trip, but the reasons were never confirmed officially. Emile was initially investigated, but prosecutors later cleared him, even issuing a letter to confirm his innocence.

Sentence and outcome

In February 2023, Roldan was sentenced to twelve and a half years in prison for second-degree murder, with more than twenty-seven years suspended. Officials said he is expected to be deported to Bolivia after serving his time.

The plea deal gave the family partial answers but left gaps. Investigators could not verify every detail of his statement. Bethany’s unborn child was also lost, and no remains were recovered.

Why the story remains

The Dateline episode about Bethany Decker resonates because it leaves contradictions unresolved. A young mother disappeared, messages were faked in her name, and years later a confession emerged that authorities themselves doubted. Even with a conviction, the lack of physical evidence and the uncertainty around what happened keep the case open in memory.

It is the mix of partial closure and missing truth that explains why people still return to this story.
