Dateline NBC “The Trouble with Sarah” January 16 2026 Recap & Preview
On January 16, Dateline NBC returns with a gripping new report titled The Trouble with Sarah, anchored by Keith Morrison. The episode unravels the complex and deeply disturbing story of Sarah Hartsfield, a woman now convicted of murdering her fifth husband, Joseph Hartsfield, and whose past relationships are clouded by fatal outcomes, suspicious circumstances, and reopened investigations.
A Life Sentence and an Ongoing Appeal
Sarah Hartsfield was convicted on October 8, 2025, by a Chambers County, Texas jury for the 2023 murder of her husband Joseph. She was sentenced to life in prison the following day and fined $10,000. Authorities say Sarah administered a fatal dose of insulin to Joseph—who was diabetic—and delayed calling 911. The prosecution emphasized not only the evidence from the scene but also patterns of behavior from Sarah’s past.
Now behind bars in Gatesville, Texas, Sarah has filed a formal appeal. Both of her original defense attorneys and the court-appointed investigator have withdrawn, citing conflicts of interest. It remains unclear whether a new attorney has been appointed to represent her in the appeal process.
A History Marked by Violence and Suspicion
Sarah’s past played a major role in the prosecution’s case. Her previous relationships included a history of alleged abuse, a fatal shooting, and accusations of plotting murder and arson. In 2018, Sarah shot and killed a former fiancé in Minnesota. That case was originally ruled self-defense, but it has since been reopened following her indictment for Joseph’s death.
Additional claims include an alleged murder plot targeting the new wife of a former husband, an arson at her family home in Missouri, and prior assault allegations from 27 years ago involving her second husband. While no charges have been filed in those earlier incidents, the prosecution presented them as part of a pattern of manipulation, violence, and escalating behavior.
The Events Surrounding Joseph’s Death
Joseph Hartsfield died on January 15, 2023, just 11 months into their marriage. Days before his hospitalization, he told family members he planned to leave Sarah and expressed fear for his life. On January 7, 2023, he was admitted to a Baytown-area hospital in a critical state due to hypoglycemia. Medical staff noticed signs that something was interfering with their efforts to stabilize his blood sugar—ultimately concluding he had been given excess insulin.
Sarah claimed she was asleep on narcotic pain medication at the time. But investigators recovered phone data showing she had been active nearly every hour and had deleted key messages. One deleted message reportedly showed Joseph “gasping” and was sent more than an hour before Sarah called 911.
Circumstantial Evidence and Final Testimony
Investigators found circumstantial evidence suggesting Sarah tried to secure control over Joseph’s personal data and finances just hours before his hospitalization. Messages from his phone to hers included his driver’s license, bank information, and Apple Legacy Contact credentials.
Detective Skyler Rocz, who testified in court, expressed regret over not collecting insulin pens found near Joseph’s bed and pointed to inconsistencies in Sarah’s timeline and phone activity. The medical examiner listed Joseph’s death as due to “complications from toxic effects of insulin,” though the exact manner—suicide, accident, or homicide—was initially undetermined.
What to Expect from the Episode
Keith Morrison’s report will walk viewers through the intricate timeline of events and explore the broader questions surrounding Sarah’s disturbing past. The episode includes courtroom footage, exclusive interviews, and expert analysis that paints a picture of a woman whose romantic history has repeatedly ended in tragedy—and whose case may not be over yet.
The Trouble with Sarah airs Friday, January 16, 2026, at 9 p.m. on NBC, with streaming available the following day on Peacock.
