Host Lester Holt revisits the case that divided Nikki’s family, devastated a small Texas community, and raised disturbing new questions about whether the state is about to execute an innocent man. This episode lays out the original case against Robert, the events surrounding Nikki's tragic death, and the perspectives of family, investigators, medical professionals, and legal counsel.

Key Discussion Points and Insights

1. Robert Roberson’s Imminent Execution and His Plea of Innocence

• Opening on Death Row: Lester Holt interviews Robert Roberson on Texas death row, confronting his impending execution.
  • Robert maintains:

    "I'm at peace if it, if it happens. But I'm not ready because I don't think I should be executed when I'm innocent." (00:53)

• This is Robert’s third scheduled execution; family and officials see it as long overdue, but a growing movement believes he is innocent.
  • Supporters call for a re-examination of the evidence:

    "Let's take all this evidence, go back to the courtroom, go back to a jury and let them decide." (01:42)

2. The Day of the Incident: Emergency Room Testimony

• Nurse Kelly Garganis’ Account:
  • Kelly describes seeing Nikki, unconscious and blue, in her mother's lap at the ER:

    "There was a jacket, so I took the jacket off and there was a baby in her lap that was blue. Literally, probably the bluest I've ever seen of a child." (04:21)

  • Observed serious head injuries and immediately suspected abuse.
• Robert’s Behavior:
  • Kelly notes Robert was emotionless and acted abnormally:

    "He had a very flat affect... not what you would normally see if it was a father taking care of their child." (05:37)

  • He claimed Nikki "fell off the bed about [12 inches]," which seemed inconsistent with her injuries. (05:17–05:24)
  • Instead of calling 911, Robert drove Nikki to the hospital, placing her on his girlfriend Teddy’s lap, who was herself a patient.

3. Law Enforcement’s Investigation and Initial Conclusions

• Detective Brian Wharton’s Findings:
  • Recalled viewing Nikki in the ER, saw obvious head trauma, and noted Robert’s detached demeanor.

    "When we talked to him, we found him very matter of fact, no emotion. And so that made us kind of put us on edge a little bit." (07:54)

  • Robert led officers through the house, showing no visible sign of violence. Robert mentioned seeing "blood on her mouth" and cleaned it with a wet washcloth—police recovered this evidence. (09:23)
  • Wharton found it odd Robert wanted a ham sandwich during the walkthrough:

    "He was hungry and so he wanted to go make a ham sandwich... Again, it was odd to us..." (09:44, 09:54)

• Investigators quickly suspected Robert, pointing to the severity of the injuries and his inconsistent account.

  "It sure felt like it, yeah." (10:12)

4. The Bowman Family: Nikki’s Grandparents

• Raising Nikki:
  • Nikki’s maternal grandparents, Larry and Verna Bowman, cared for her from birth.
  • After Robert regained custody, they had no legal recourse to keep her, as Texas law defaulted to parental rights if either parent was deemed fit.

    "She had never been with anybody but Us up until Robert got her and we really had no choice on that matter. State of Texas... grandparents don't have a say." (15:33)

• Verna and Larry recount their heartbreak and persistent feelings of helplessness:

  "I didn't do all I could to keep her from it. I don't know what else I could have done, you know?" (12:49)

• The Night Before:
  • Nikki was reluctant to leave with Robert, which in hindsight, deeply troubles the grandparents.

5. The Medical Evidence: Shaken Baby Syndrome

• Dr. Janet Squires' Testimony:
  • Nikki was diagnosed with classic "triad" injuries: bleeding behind the eyes, brain swelling, and internal bleeding—commonly linked at the time to shaken baby syndrome.
  • Based on this, authorities believed Nikki was a victim of fatal abuse.
• Life Support Decision:
  • Judge transferred medical decisions to the Bowmans, who reluctantly agreed to remove Nikki from life support after prognosis was declared hopeless.

    "Before they took her off the life machine, they let mama hold her before they shut her off..." (17:09)

6. The Prosecution’s Case and Trial

• Trial Proceedings:
  • Lead prosecutor Doug Lowe declined to be interviewed, but Robert’s court-appointed defense attorney Steve Evans (longtime acquaintance) provides inside perspective:

    "Robert really didn't have the personality that was aggressive or violent." (20:19)

  • Evans, however, after reviewing the case file, doubted Robert’s innocence:

    "Something happened to that child... That child had a number of injuries, and he was the only one there." (20:37)

• Plea Bargain Offers:
  • Multiple plea deals (max of 50 years) were offered; Robert rejected all, insisting on his innocence.

    "Oh, hell, yes." (Would a plea have been a victory?) (21:21)

7. Damning Testimony & Jury Reaction

• Testimonies:
  • Nurse Kelly (ER), Detective Wharton, Dr. Squires (specialist), Dr. Urban (medical examiner) all testify to evidence of abuse and violent injury.
  • Teddy Cox (Robert’s girlfriend) and her daughter both testify to prior physical abuse and violent shaking of Nikki by Robert. The daughter’s demonstration with a teddy bear leaves an impression.
• Defense Challenges:
  • Evans questioned the reliability of Teddy Cox and presented a witness (her sister) vouching for Robert’s gentle nature.
  • Defense ultimately conceded “something happened” but attempted to explain Robert was an overwhelmed parent, not a murderer.

8. Juror Perspective

• Juror Terry Compton:

  "Mainly when I would glance, you would see him just sitting there in the chair with his hands on top of the table. He basically just sat there." (26:08) "They could see what was all going on in her brain and how much bleeding... and they actually passed those or showed those pictures in court." (26:24)
  "I sit there and thought, well, yeah, now I can see where, you know, if you have a man, Robert size shaking a baby, I could see where it maybe could have done some violently brain damage." (26:47)

• Swift Verdict:

  • Deliberations were quick; the evidence seemed overwhelming.

    "I'd say everybody pretty much had their mind made up." (27:04)

9. Seeds of Doubt and Unanswered Questions

• Emergence of New Advocates:
  • Years after conviction, a new supporter (unidentified in this episode) began investigating and found troubling holes in the original story:

    "Every time I turn around, there was something new. I'm reading medical records and I'm about to fall out of my chair." (27:38)

• Cliffhanger for Next Episode:
  • Promises revelations about new evidence and mistakes made in the case:

    "We made mistakes because we didn't have all the information." (27:49, preview)
