  • Despite Cindy’s attempts at CPR, and the rapid arrival of emergency services, Todd dies.

Cindy’s Early Behavior and Grief

• Initial Grieving
  Cindy’s coping is immediacy and avoidance—she recounts compartmentalizing her grief, acting as if Todd was simply "on deployment" ([30:30] Cindy Summers).

  • Cindy responds candidly about her behavior:

  • Her financial actions—trust funds for the children, but also a spree of luxury purchases—raise eyebrows:

    • “Yeah, I bought a Tiffany’s ring, and I’m wearing it right now… I thought that it would make me feel better…” — Cindy Summers ([32:49])

Early Investigation and Autopsy

• NCIS Initial Findings

  • Todd's death appears natural at first; routine investigations find no signs of foul play ([27:10] summary; [28:14] NCIS Agent Rob Terwilliger).
  • The autopsy: cause of death is stated as heart failure, unusual but not unheard of for a healthy young man.
  • Life insurance and death benefits are paid out quickly to Cindy—“at the time, the standard for the armed services” ([29:23]).

• Gossip and Judgment

  • Rumors swirl in the community about Cindy’s behavior, her relationships, and new spending habits.
  • Neighbors report her children as unsupervised and her home as the new "party central" ([33:19]).

The Case Turns: Suspicion and the Reopened Investigation

  • The case lingers on the desks of multiple NCIS agents due to transfers and reassignments ([34:41]).

• The Call for Further Testing

  • A recommendation is made to test Todd’s samples for poisons, specifically heavy metals like arsenic ([36:05]).
  • “What happens is that the panel will review it, find that all the investigative leads have been followed, and then they would recommend it for closure.” — NCIS Agent Rob Terwilliger ([28:14])
