A wife goes missing in the Bahamas. Utah mom's alleged plot to kill son-in-law. Plus, crimes abroad.

This episode of Dateline True Crime Weekly dives into three high-profile cases across the globe. First, the mysterious disappearance of Lynette Hooker in the Bahamas, where her husband Brian was questioned after claiming she fell overboard during a dinghy trip. Despite no physical evidence of foul play, inconsistencies in Brian’s story, a volatile history between the couple, and the delayed 911 call have fueled suspicion. The U.S. Coast Guard has joined the investigation, and the search is expected to be suspended soon. Next, the trial of Tracy Grist, a Utah mother accused of orchestrating the murder of her son-in-law Matt Restelli with her daughter and son. Prosecutors argue she was the mastermind behind a plot that began as a joke but escalated into a deadly conspiracy, backed by incriminating texts and timing discrepancies. The defense claims it was a chaotic moment, not a planned murder. Finally, updates on high-profile appeals: Sean Diddy Combs challenges his Mann Act sentence, while Lori Vallow Daybell seeks a new trial, citing a conflict of interest with her appointed attorney. Retired FBI agent Frank Figliuzzi offers guidance for Americans abroad, emphasizing the importance of registering with consulates and understanding that U.S. citizenship doesn’t grant immunity from foreign law enforcement. Key takeaways include: 1) Always register with your nearest U.S. consulate when traveling internationally; 2) Foreign legal systems differ significantly from U.S. procedures, especially in detention and interrogation; 3) Even if you’re an American, you are not immune to arrest or prosecution abroad; 4) Inconsistencies in a victim’s story—like delayed emergency calls or emotional detachment—can raise red flags in missing persons cases; 5) Domestic violence allegations, even without formal charges, can be critical context in criminal investigations; 6) Text messages and digital evidence are often pivotal in proving conspiracy; 7) Jurors may be swayed by behavioral cues, such as body positioning or tone of voice; 8) Appeals in high-profile cases can take months or years, with no guaranteed outcome.
