Podcast: Dateline NBC
Host: Lester Holt
Guest: Andrea Canning (Dateline Correspondent)
Episode Air Date: September 24, 2025
Episode Overview
This episode of Talking Dateline delves into the tragic and troubling case surrounding the death of Sandra Birchmore, a 23-year-old teacher's assistant found dead in her Massachusetts apartment in 2021. Initially ruled a suicide, the circumstances surrounding Sandra’s death—and her relationship with members of the Stoughton Police Department—sparked a deeper investigation and intense emotional responses from both her family and law enforcement. Host Lester Holt and correspondent Andrea Canning discuss the investigation, the personal and community impact, and unanswered questions that persist as the case moves toward trial.
Key Discussion Points & Insights
Sandra Birchmore’s Background and Vulnerabilities
- Family Circumstances: Sandra was raised by her mother (who had chronic health issues and passed away while Sandra was young) and supported by her grandparents.
- “She wanted to give Sandra, an only child, a good life… enrolled her in the Stoughton Police Explorers program.” – Andrea Canning [01:46]
- Police Explorers Program: Intended as a safe, supportive program exposing youth to law enforcement, it instead brought Sandra into contact with problematic officers.
- “…everything went so wrong… because who she was exposed to in this program.” – Andrea Canning quoting Chief McNamara [02:56]
Sandra’s Personality and Pregnancy
- Complex Personality: Described as naive, sometimes childlike despite being a young woman. She was both open (oversharing private matters) and secretive.
- “She went to her boss at school and said, you know, I'm having a baby with a married man.” – Andrea Canning [03:37]
- Desire for Family: Speculation that Sandra’s longing for a child was linked to her desire for familial connection, possibly filling the void left by her mother’s death.
- “…maybe this baby was filling some kind of a void. But she was very, very excited about it.” – Andrea Canning [03:48]
The Death Investigation: Community and Family Doubt
- Immediate Skepticism: Sandra's family instantly doubted suicide as a cause of death, citing her excitement about the baby and tendency to share emotional events.
- “They were like, if he broke up with her, she would have told somebody. She was also so excited about the baby that that also didn't make sense to them.” – Andrea Canning [04:37]
- Physical Evidence Overlooked: The family found broken jewelry (a necklace with a flamingo pendant) suggesting possible struggle, but the local police were dismissive until external experts stepped in.
- “…it looks like… maybe there was a struggle… the police, they said, didn't do anything about it.” – Andrea Canning [05:00]
The Role of Dr. Michael Baden and New Evidence
- Independent Medical Examination: Famed forensic pathologist Dr. Michael Baden, brought in by Sandra’s aunt, concluded Sandra’s death was a homicide, not a suicide.
- “…he took one look at it, and he said, you know, this is homicide. This is not a suicide.” – Andrea Canning [06:15]
- Critical Surveillance Footage: Surveillance captured a Stoughton police officer in Sandra's apartment for 29 minutes before her death, highlighting stark evidence.
- “…he was up there for 29 minutes… then ends up at the hospital to deliver his third child.” – Andrea Canning [06:38]
The Officers Under Scrutiny & Ongoing Legal Proceedings
- Matthew Farwell: Stoughton police officer, married, and alleged to be in a relationship with Sandra. He has pleaded not guilty; subsequent findings indicate he is not the father of Sandra’s child.
- “…he's apparently not even the father of the baby… so much is centered around…the impending birth of this child, that he didn't want this child. And then come to find out…he's not the dad.” – Andrea Canning [07:10]
Police Leadership and Accountability
- Chief Donna McNamara's Response: While deeply affected personally and professionally, Chief McNamara initiated a transparent internal investigation and publicly disclosed disturbing findings.
- “She just said…‘I need to take a look at my department and what's going on here.’” – Andrea Canning [09:49]
- “If this was one of your family members… some of those text messages that I read…” – Andrea Canning [10:16]
- Bravery and Openness: Chief McNamara’s willingness to talk openly, hold a press conference, and release findings were pivotal in advancing the case.
- “I was just so impressed that she came forward…there was…I don't think there was one question I asked her that she did not answer.” – Andrea Canning [12:48]
FBI Involvement and Community Pressure
- Delayed Yet Decisive Action: Family, media, and Chief McNamara’s advocacy prompted federal intervention and an arrest, despite initial warnings about slow resolution.
- “…the family was not going to give up…they got an arrest.” – Andrea Canning [16:16]
- “The FBI in this case said, you might not hear from us for a while…But they were thrilled that they were on it.” – Andrea Canning [14:34]
- Media and Public Pressure: The Boston Globe, other journalists, and podcasters kept the case alive in the public eye.
