In "Secrets in the Smoky Mountains," Dateline NBC unravels an extraordinary true-crime story entwining love, betrayal, military valor—real and counterfeit—a web of fraud, and, ultimately, murder. The decades-long saga traces the rise and crumbling of a "power couple" in Appalachia, exposing years of intricate lies, stolen valor, and the chilling orchestration of a husband’s death for love and money.

  • Bob, a decorated Marine and sheriff's detective, settles with wife Martha Ann in Tennessee after facing struggles including PTSD.
  • Bob is beloved by family and friends, known for his kindness, humor, and love of animals.
  • Martha Ann is described as intelligent, charming, and the backbone for her two sons (one adopted, Sean).
  • Their life appears idyllic, with close friendships and church involvement.

• Bob’s PTSD & Downward Spiral:

  • May 2006: Bob is found dead in his recliner, with a gun and empty pill bottle. Chuck calls 911 (09:08, 11:06).
  • Police find a Do Not Resuscitate order; death appears to be a suicide by overdose (11:42).
  • Loved ones are shaken yet somewhat accepting due to Bob’s mental health history. Yet, immediacy and manner of death, and Chuck's calm demeanor, raise quiet suspicions.

  “When DATELINE continues. It was the 15th of May, 2006... Bob McClancy, 56 years old, was lying in his favorite recliner... The caller, a family friend, said the body was already cold.” —(09:58)

2. Transformation: Grieving Turned Glamorous (24:30–37:49)

• Martha Ann and Chuck Grow Close:

  • Their relationship develops publicly after a Caribbean cruise, where they share a cabin and eventually announce their marriage (27:15–41:46).

  • Martha Ann claims to have joined the FBI and State Department, with stories of secret missions, high-level government work, and even travel on Air Force Two (31:41–32:26).
  • Chuck appears at veterans’ events with a chest full of medals, is revered in veterans’ organizations, and receives accolades for purported service (34:50–36:32).

  “She told me one day that she met a man from the FBI and he offered her a job as a secretary... she would be traveling out of the country on secret missions.” —Kathy (31:41)

3. The House of Cards Shakes (37:49–43:56)

• Cracks Appear:

  • Chuck begins drawing militaristic scrutiny; fellow Vietnam veterans find his war stories grandiose and suspect, noticing they never heard of him during service.
  • After Chuck presents military records, doubts deepen, and the Air Force is contacted; his service documents, initially appearing legitimate, begin to unravel as forgeries.

  “The people who had served with him were very emphatic that he had not participated in these missions… turns out the Air Force really started pouring over these documents… and rather quickly determined that these were all forged documents.” —Investigator Nate Landkammer (44:10–45:01)

4. Crime, Fraud, and Deeper Investigation (43:56–54:49)

• Fraud Exposed:

  • VA investigator Nate Landkammer uncovers a monumental fraud: Chuck’s entire military record is fabricated, and Martha Ann also fakes a background as a decorated officer (47:18–48:23).
  • The couple collects about $10,000/month in fraudulent VA and Social Security disability benefits, with both claiming to be homebound and wheelchair-bound while conducting strenuous physical labor caught on surveillance (49:08–51:49).
  • Investigators lay traps—scheduling simultaneous medical appointments to expose they only own one wheelchair (54:49).

  “We started doing surveillance... we would observe them doing hours and hours of yard work outside their home, very strenuous stuff.” —Nate Landkammer (50:57)

5. Revelations, Evidence, and a Widening Net (59:02–67:48)

• Sean’s Dilemma and Key Evidence:

  • Martha Ann’s son Sean, who had assisted with clearing Martha Ann’s home, discovers shocking photos on her old computer: images of Bob’s death, taken before first responders arrive, showing the murder staged as a suicide (59:02–60:39).
  • Sean contacts investigators, who re-examine the earlier case—previously ruled suicide, with tampered evidence charges dismissed since photos were collected without a warrant from Chuck’s camera.
  • Now, with additional statements and forensic review, investigators suspect murder and conspiracy.

  “Here were the pictures that told an entirely different story... you could tell that was body manipulation.” —Sean (60:19–60:39)

  “Her spontaneous reaction…was, for God’s sake, Sean, delete those photographs. You know, and that was kind of what we were looking for.” —Nate Landkammer, recounting Sean’s recorded undercover call (74:15–74:25)

6. Trial and Ultimate Truth (75:12–89:48)

• The Courtroom Drama:

  • Martha Ann stands trial for first-degree murder and conspiracy; maintains her innocence, painting herself as a victim of Chuck’s cons (77:24–78:04).
  • Chuck turns state’s witness: he and Martha Ann had an affair; she masterminded the plan, overdosing Bob with “magic dust” (ground medication) over several days, culminating in his death (84:28–86:14).

  “For days before Bob died…Martha Ann ground up the pills into something she called magic dust…The doses got bigger and Bob more disoriented” (85:14–85:22)

  • Chuck describes staging Bob's death scene to look like suicide, with photos for leverage with the VA.
  • The prosecution presents a “keep it simple” case focused on the forged will, manipulated wedding dates for maximizing benefits, and the chilling aftermath.
  • Friends and family testify to Martha Ann’s coldness and duplicity, with Sean, her own son, taking the stand against her.

  “She looked at me as if she wished I was dead. She looked at me with the most hate I've ever seen from anyone.” —Sean (83:12)

  • The jury acquits Martha Ann of first-degree murder but finds her guilty of attempted murder and conspiracy (88:19, 88:29).
  • Martha Ann receives a 50-year sentence (later halved on appeal and commuted for parole); Chuck is sentenced to 25 years for his role.

  “The slow poisoning and slipping of life from an individual is exceptionally heinous. He gave her the max. 50 years in prison.” —Judge (89:42)

7. Aftermath and Epilogue (90:32–91:54)

• Reflections on Justice and Family:

  • Sean, traumatized by testifying against his own adoptive mother, seeks closure by searching for his biological roots with DNA testing, finding and connecting with his birth father in Maine.
  • Friends and family remain stunned by the depth of betrayal and evil displayed by Martha Ann and Chuck, feeling a mixture of relief and enduring sorrow.
