2. Utah Murder Plot: Tracy Grist and Family on Trial

Segment begins at 12:28

Overview:

• Crime: Matt Rastelli was found shot outside his mother-in-law Tracy Grist’s home. Initially ruled self-defense, but investigation suggests a plot involving Tracy, her son Kevin, and Matt’s wife Kate.
• Twist: Kate, originally charged, turned state's witness, describing her mother's manipulation and the plan to murder Matt rather than face a messy divorce and custody fight.

Key Discussion Points:

• Relationship troubles:
  COVID strained Matt and Kate’s marriage, leading to Kate’s abrupt move to Utah (14:48–15:43).
• Suspicion on self-defense:
  Discrepancies in evidence (knife in wrong hand, delayed 911 calls) led investigators to suspect murder (15:55–17:03).
• Text evidence:
  Prosecution introduces texts where Tracy muses about strangling Matt; prosecution alleges conspiracy (17:19–17:47).
• Kate’s testimony:
  “She had said it like a joke. Oh, we can get him to come out here, and we could just murder him and kill him and make it look like self defense.”
  —Kate via Andrea Canning (19:25)
• Shift from joke to reality:
  “About a week and a half beforehand, when I realized that a divorce with him would be messy and I would run the risk of losing my children.”
  —Kate via Andrea Canning (19:41)
• Mother's influence:
  “I don't think that's a fair question. It was planned by my mother.”
  —Kate via Andrea Canning (20:23)
• Trial status:
  Three-week trial expected, possible testimony from Kevin, the convicted shooter (21:09–21:18).
