Dateline Originals: The Last Appeal

Episode 2: “I’m Astonished”
Host: Lester Holt (NBC News)
Original Release: January 15, 2026

Episode Overview

In this gripping installment, Dateline delves deeper into the case of Robert Roberson, a Texas father on death row for the death of his two-year-old daughter, Nikki. The episode explores critical flaws in the investigation and prosecution, questions the now-discredited “shaken baby syndrome” diagnosis, unveils new insights into Nikki’s health, and exposes the troubled defense Robert received at trial. With newly surfaced perspectives and emotional testimony, the narrative challenges whether Texas may be preparing to execute an innocent man.

Key Discussion Points and Insights

1. Robert Roberson’s Denials and Story

• Robert’s Claim of Innocence

  • Robert, facing execution, maintains that he did not harm his daughter Nikki and has never wavered in this assertion.
  • “No, sir, I did not harm my daughter.” – Robert Roberson (00:58)
  • Describes the day Nikki fell out of bed and his disbelief at how quickly suspicion turned toward him.

• Immediate Suspicion by Authorities

  • Medical staff doubted Robert’s account and quickly involved law enforcement.
  • “They didn’t believe my story. They called the detectives in…” – Robert Roberson (01:38)

2. The Shaken Baby Syndrome Debate

• History and Rise of Shaken Baby Diagnosis

  • The episode traces the rise of shaken baby syndrome in the legal system, referencing the 1997 “nanny trial” of Louise Woodward as a cultural turning point (05:13).
  • Lester Holt underscores how the triad of symptoms (brain swelling, brain bleeding, retinal bleeding) became nearly synonymous with criminal shaking—even as the scientific basis eroded over time.
  • Notable Quote: “It became a sort of easy way into jail.” – Dr. Norman Guthkelch (06:58)

• Discrediting the Science

  • Recent scientific developments reveal these symptoms can be caused by multiple ailments—falls, infections, or oxygen deprivation—not just abuse (06:10).
  • Texas passes a “junk science” law allowing convictions based on outdated science to be challenged (07:26).

• Legal Strategy to Halt Execution

  • Defense attorney Gretchen Swinn scrambles to file a “junk science writ” to halt Robert’s execution, managing to win a new hearing (07:47, 08:06).

3. Nikki’s Medical History: What the Jury Never Heard

• Contradictory Portrayals of Nikki’s Health

  • Nikki's grandparents recall her as generally healthy, while Gretchen’s investigation paints a drastically different picture from medical records.
  • “This child has been sick from day one.” – Gretchen Swinn (11:19, 15:23)

• Chronic Illness and Risky Medications

  • Nikki had over 40 medical visits, recurring fevers, infections, sleep apnea, and hospitalizations before her death (11:36, 12:00).
  • Days before her death, Nikki was prescribed Phenergan and codeine—drugs later found to be dangerous for young children with respiratory issues (12:09, 13:17).

• Trial Oversight

  • The defense failed to present Nikki's extensive medical history, dismissing it as irrelevant, severely limiting the jury’s understanding.
  • “Yet at trial, all of her medical history was dismissed as minor, insignificant, not relevant to any of this.” – Gretchen Swinn (15:23)

4. Defense Failures and Strategic Missteps

• Steve Evans, the Trial Attorney

  • Evans, Robert’s original defense attorney, appeared to endorse the shaken baby narrative, allegedly sabotaging his own client.
  • Notable Quote: "I almost cannot believe what I'm reading." – Gretchen Swinn (15:50)
  • Trial Transcript Confusion: While Evans claims he defended Robert by denying a shaking incident, court transcripts show he referred to it as “a shaken baby case,” undermining the accidental fall theory (16:29, 16:54).
  • Even Evans later admits, “I’m astonished by what you’ve related of the transcript.” (17:43)

• Effect on Verdict

  • Evans describes how, in capital cases, sometimes the defense aims only to save a client’s life, not exonerate. “You save their life.” (18:04)

5. Insights into Robert’s Personality and Perception

• Community Testimonials

  • Interviews with family and friends, including his brother Thomas and sister-in-law Jennifer, describe Robert as gentle and loving—never violent, especially towards Nikki (20:49-21:17).

• Diagnosis and Misinterpretation

  • Gretchen reveals Robert’s diagnosis with autism, explaining his flat affect and unconventional emotional responses, which may have been misinterpreted as suspicious or uncaring (23:19-24:57).
  • “He has no guile. He does not lie. He takes everything very literally.” – Gretchen Swinn (24:01)
  • Witnesses testified about his “flat affect,” misjudging his autistic characteristics for guilt (24:24).

6. Questionable Witness Testimony and Compelled Statements

• Challenging Accusations of Abuse

  • Gretchen revisits witness statements, including those from Robert’s girlfriend and her relatives.
  • Sister-in-law Patricia Conklin asserts under oath that Robert was never abusive.
