Dateline went back to Sandra Birchmore's homicide and learned five surprising facts that change individuals' impression of her homicide. Birchmore's case in 2021 was initially thought to be a suicide, but Dateline investigations and the news that followed established evidence proving that it was a homicide.

The case, "The Betrayal of Sandra Birchmore," intertwines new forensic data, freshly untethered video, and interviews that shed light on her affair with Matthew Farwell, a disgraced cop. Dateline follows how a decades-old suicide case was reopened as a murder case, exposing power, secrecy, and accountability abuses on the part of police officers.

Here are five harrowing details about Sandra Birchmore's murder, pointed out by Dateline

1. A reported affair began when Birchmore was in her teenage years

Dateline continues to report that Sandra Birchmore came into contact with Matthew Farwell for the first time via the Stoughton Police Explorers Program when she was 12. Prosecutors allege the s*x was at 15, though Farwell at that time was in his late 20s. Farwell contests this and has stuck to their s*xual relationship, commencing only when Birchmore was 22 and an adult.

This highlights that the first meeting between Farwell and Birchmore created a strong bond, which prosecutors allegedly claim was exploitative and manipulative. The program emphasizes that the meeting was not accidental but a result of years of engagement with serious ethical and legal implications.

2. Other officers were said to be having improper exchanges

Dateline's bombshell number one is that Birchmore's contact wasn't one and done with Matthew Farwell. In messages revealed by the investigators, William Farwell, Matthew's twin brother, purportedly requested sensual images and videos from Birchmore. Another officer, Robert Devine, a previous supervisor of the Explorers Program, was also linked to wrongdoing through inappropriate communication.

The show adds complexity to the revelations by suggesting an endemic issue of blurred boundaries among authority figures and a breaching of a young woman. Dateline does not speculate about the motives of institutions but instead presents evidence of several connections, implying that Birchmore's contact with officers might have influenced how her case was initially handled.

3. Media and public pressure reopened the case

Dateline also highlights the media's and public pressure's role in keeping the case in the spotlight. Investigative reporter Michele McPhee and the podcast kept uncovering public inconsistencies and loose ends. These eventually led authorities to release security footage outside Birchmore's apartment complex, where they recorded Matthew Farwell entering and leaving on the night she was murdered.

This recent video confirmed it. The visual evidence once again caused doubt among federal investigators and the public, and the media's persistence raised questions about the official story. The case illustrates how external pressure influences whether to close or reopen an investigation spotlight.

4. Forensic evidence contradicted the initial suicide conclusion

In its extensive report, Dateline outlines how forensic examination of new evidence discredited the initial suicide theory. The family retained forensic pathologist Dr. Michael Baden to revisit the case and conclude that Birchmore's death was highly probable to have been homicide by strangulation. Among the evidence overlooked in the initial case, a broken necklace was found at the crime scene.

Dateline shows how forensic evidence failed to prove guilt but again states that the decision of suicide was not based on sufficient evidence. Based on these facts, the program demonstrates how undervalued facts and other medical data can influence the credibility of a case.

5. Indictment of Farwell and pregnancy discovery

One of the most dramatic cases reopened by Dateline is the 2024 federal indictment of Matthew Farwell. He was charged with killing a witness or victim and pleaded not guilty. Prosecutors previously stated that Birchmore's pregnancy was likely the motive, as it would have damaged Farwell's reputation and private life.

But there are also complications: DNA tests confirmed that Farwell was not the biological father of Birchmore's pregnancy. This complication reintroduces motive assumptions and raises the question of whether the case is as complex as it appears.

The show also reports that the wife of Farwell had delivered their third child within less than 13 hours of the Birchmore murder, another bit of tragic timing and parallel universes that the parties are forced to face.

Hence, Dateline's investigation of the Sandra Birchmore case cites five giant facts: purported grooming over years, involving other officers, intimidation by the media, forensic discrepancies, and Farwell's indictment. Shedding so much light on it, the show chronicles how a former rejected suicide case evolved into a real homicide investigation.

The series is not sensationalizing but instead documenting evidence, interviews, and recordings of how the investigation was carried out. The reporting ultimately emphasizes the importance of responsibility, transparency, and perseverance in uncovering the truth behind heinous cases.
