Overview of Dateline True Crime Weekly (NBC News)
This episode covers several major true-crime developments, led by a deep dive with Lester Holt into the Luigi Mangione case and how investigators tracked him after the killing of UnitedHealthcare CEO Brian Thompson. The show also updates listeners on the unusual Cleveland case where a divorce attorney is accused of luring his client to her death, plus courtroom developments in Arizona and San Diego. It closes with an expert explanation of why ankle monitors can fail and why electronic monitoring is not the foolproof safeguard many assume it is.
Luigi Mangione and the UnitedHealthcare CEO Killing
Lester Holt previews his special Dateline investigation into the December 2024 ambush killing of Brian Thompson in Midtown Manhattan.
What happened
- Brian Thompson, CEO of UnitedHealthcare, was shot and killed outside a Hilton hotel in New York City.
- Police say the attack was premeditated.
- Five days later, police arrested Luigi Mangione at a McDonald’s in Altoona, Pennsylvania, after a tip from customers who thought he matched the suspect.
- Mangione has pleaded not guilty to state murder charges and a federal stalking charge.
What Lester Holt learned
- Investigators used a backwards-tracing strategy through extensive security footage.
- A key break came when Mangione lowered his mask at a hostel, allowing police to capture his face on camera.
- He allegedly used a false ID, which helped connect him to the case.
- Police also found a handwritten note in his backpack that suggested he believed his actions were “right or justified.”
- The motive for choosing Thompson and UnitedHealthcare remains unclear.
Why the case stands out
- Mangione has become a highly polarizing figure online and in public discourse.
- Holt notes that the case feels unlike others because of the intense public reaction and the way the victim has been overshadowed.
- The special features first-ever interviews with original investigators and someone from Thompson’s inner circle.
Trial concerns
- Jury selection is expected to be extremely difficult because of the publicity.
- The episode raises the possibility of jury nullification and the challenge of finding impartial jurors in New York City.
Cleveland Cold Case: Divorce Attorney Accused of Client’s Murder
The episode then turns to the 2013 murder of Aliza Sherman, an IVF fertility nurse and mother of four, who was stabbed to death in downtown Cleveland.
The case
- Sherman texted her divorce attorney, Gregory Moore, before arriving at his office.
- When she got there, the door was locked.
- Prosecutors say Moore told her he was there, but building records allegedly show he was not inside when he claimed to be.
- A hooded attacker then stabbed Sherman nearly a dozen times.
The current charges
- In 2025, Moore was indicted on murder and kidnapping charges.
- Prosecutors allege he lured Sherman to the office and killed her because he was not ready to take her divorce case to trial.
- Moore has pleaded not guilty.
Defense arguments
- His lawyers say the state charged the wrong person.
- They argue the 12-year delay has made a fair trial impossible.
- They say key witnesses have died and evidence has been lost.
Context and motive theory
- Prosecutors point to Moore’s past, including prior accusations that he called in bomb threats when unprepared for cases.
- They argue this case may have been a far more violent version of that same pattern.
Dateline Roundup
Arizona Murder Case: Mistrial in Penalty Phase
- Ian Mitchum was convicted in the 2015 rape and murder of Allison Feldman, a medical sales rep in Arizona.
- After months of trial, the jury deadlocked in the penalty phase.
- A juror was removed for seeking outside information, and another failed to appear.
- The judge declared a mistrial only for sentencing, not for the underlying conviction.
- Prosecutors must now decide whether to pursue the death penalty again or accept life imprisonment.
San Diego County: “Spellcaster” Murder Trial
- The trial of Larry Miliete continues in the disappearance and presumed murder of his wife, Maya Miliete, who vanished in 2021.
- Prosecutors say he paid for “magic spells” and killed her after learning she planned to leave him.
- Witnesses testified that Larry allegedly talked about hiring someone to “get the other guy,” referring to Maya’s alleged affair partner.
- Security video showed Maya returning home, but no footage has been found showing her leaving again.
- The prosecution is trying to build a case without a body, which makes the trial especially difficult.
Ankle Monitors: How Reliable Are They?
The episode’s final segment examines the limits of GPS ankle monitors after two murder defendants in Harris County, Texas, allegedly removed theirs and fled or tried to flee.
Cases discussed
- Lee Gilly, charged in the deaths of his pregnant wife and unborn child, allegedly cut off his ankle monitor and fled to Italy.
- Walter Pozos, charged with murder, allegedly cut off his monitor days later and is still at large.
Expert takeaways from Joseph Russo
- An estimated 300,000 to 400,000 people may be on electronic monitoring at any given time.
- There is no national database or perfect centralized tracking system.
- Monitors can enforce:
- Curfews
- Inclusion zones
- Exclusion zones
- The devices are not impossible to remove:
- They’re designed to be cut off in emergency situations
- They can be removed with the right tools and enough time
- The biggest weakness is not usually the technology itself, but the human response:
- Alerts are not monitored like a movie-style command center
- Law enforcement often cannot respond in real time
- Overload and staffing shortages make rapid enforcement difficult
- Russo estimates true system failures are rare, likely under 1% of cases.
Key Takeaways
- The Luigi Mangione case is being framed as both a major criminal investigation and a cultural flashpoint.
- The Aliza Sherman case shows how long-running cold cases can suddenly re-emerge with serious new charges.
- The roundup stories highlight how murder trials can still turn on jury issues, witness testimony, and incomplete evidence.
- Ankle monitors provide supervision, but they are not a guarantee against escape or noncompliance.
What to Watch Next
- Lester Holt’s special, “A Killing in Midtown,” airs Friday on NBC.
- The Cleveland case against Gregory Moore is set for trial in September.
- Sentencing and possible retrial decisions in the Arizona case will follow the mistrial in the penalty phase.
- The San Diego case will continue as prosecutors build a circumstantial case without a recovered body.
