Episode Overview

This episode of "Talking Dateline" dives into the haunting true-crime mystery from the Dateline episode "A Perfect Spring Morning." Host Lester Holt sits down with reporter Blaine Alexander to discuss the decades-long quest for justice in the 2001 murder of Leslie Preer in Maryland. The story centers on Leslie’s devoted daughter, Lauren, the misdirected suspicion that fell on her father, and the justice that arrived 20 years later thanks to DNA and determined detectives.

Key Discussion Points & Insights

1. Case Background and Emotional Impact

• Leslie Preer, a loving mother and wife, was murdered at home in 2001. Investigators quickly suspected her husband, Sandy, but after years of uncertainty and family anguish, the killer turned out to be Lauren’s high school boyfriend, Eugene Bleagor.
• The case remained cold for two decades, kept alive by Lauren’s persistent advocacy.

Notable Quotes:

• “At the core of this, this is about a daughter who embarked on this decades-long quest to find her mother’s killer. In talking with Lauren Preer, it was very clear immediately that she and her mom, Leslie, had the kind of mother-daughter relationship that you dream of having.”
  — Blaine Alexander [02:19]

2. The Toll of Suspicion on the Family

• Sandy Preer, Leslie’s husband, remained under a cloud of suspicion until his death, poisoning family relationships and inflicting further pain.

Notable Quotes:

• “He went to his grave not knowing who the real killer was and still feeling like ... there were all these people and all these eyes on him. That’s something that Lauren really spoke to... a pain she still carries.”
  — Blaine Alexander [04:18]
• “When Lauren finally confronted her dad and asked him point blank, ‘Did you kill my mom?’ and he said no, that was a very powerful segment.”
  — Lester Holt [05:10]

3. Personal Aftershocks for Lauren

• Lauren’s trauma from the experience, including the fear triggered by showers (the site of her mother’s murder), highlights the lingering impact of violence and unresolved cases.
• Blaine describes how Lauren’s friend Lisa would sit in the bathroom while Lauren showered for years after the murder [03:25].

4. Police Investigation: Mistakes & Polygraph

• Police focused on Sandy, fueled by his seemingly odd behaviors and a failed polygraph, though his DNA ultimately didn’t match the evidence.
• The use (and limitations) of polygraphs is discussed, with warnings that their results are not foolproof or admissible in court.

Notable Quotes:

• “You volunteer to take a lie detector test and then you fail it, that just doesn’t look good.”
  — Blaine Alexander [07:43]
• “But once again, the polygraph kind of started pointing toward the husband.”
  — Lester Holt [07:32]

5. Breakthrough via DNA and Detective Work

• The case pivoted when advances in DNA technology allowed new detectives, Tara Augustin and Jeanne Dupuy—described as "dynamic, Taylor Swift-loving working moms"—to reopen the file and match evidence to Bleagor.
• The process of genetic genealogy was painstaking, but ultimately led to a “movie moment” of discovery.

Notable Quotes:

• “This case passed through the hands of eight detectives... these two new detectives not only went through the cold case files... but also spoke to Lauren and kind of heard her voice.”
  — Blaine Alexander [11:26]
• “She shouts out, ‘I got it, I got it.’ You kind of feel that electricity.”
  — Blaine Alexander [13:49]

6. Confronting the Truth About the Killer

• Bleagor lived in plain sight, even comforting Lauren at times—adding to the chilling realization for the family.
• Lauren’s “internal barometer of who to trust” was shattered when she learned her friend was the murderer.

Notable Quotes:

• “Not only can you commit this crime, but then proceed to live your life as though nothing had happened and even come face to face with the people that you hurt so badly.”
  — Blaine Alexander [14:25]
• “When you think about all of the motherly love that Leslie poured into any kid who was in her house back in the day, including Eugene, then that just kind of heightens the sense of betrayal.”
  — Blaine Alexander [15:42]

7. Family & Community Aftermath—The Search for Closure

• The Preer family’s pain extends beyond the eventual conviction: “closure” remains elusive.
• Leslie’s brother Bill’s courtroom remarks frame the depth and permanence of the family’s loss.
  [17:32–18:56] (Bill Preer speech)

Notable Quotes:

• “Closure is impossible. Our pain lingers for the rest of our lives... There was no closure proceeding for Leslie.”
  — Bill Preer, court statement [17:32]

8. Listener Q&A—Police Process & Social Media Insights

• Why didn’t police look more at ex-boyfriends?
  Focus on Sandy, limited resources, and high-profile competing cases led to missed leads, even though Lauren herself named Bleagor early on.
  [22:03]

• Bosses checking on missing employees:
  Both Lester and Blaine found it notable and slightly odd, acknowledging that workplace cultures differ and what triggered the welfare check in Leslie’s case may not be universal.
  [23:15]

• Family reactions and police suspicion:
  Not everyone processes or expresses grief the same way, making it dangerous to rely solely on first impressions.

Notable Quotes:

• “Who knows how someone is going to react in that type of situation... You just don’t know.”
  — Blaine Alexander [24:23]
• “Glegor shed a few crocodile tears.”
  — Lester Holt [24:44]
