Murder: True Crime Stories
HOLIDAY SPECIAL: Thanksgiving Murders Pt. 1
Date: November 25, 2025
Hosts: Vanessa Richardson, Dr. Tristan Ingalls, Carter Roy (guest)
Episode Overview
This Thanksgiving special explores the darker side of the holiday—when family gatherings end in tragedy, not gratitude. The episode focuses on two notorious Thanksgiving Day murder cases: the rampage committed by Paul Merhige against his own family, and the disturbing tale of Omaima Nelson, whose troubled past and volatile marriage led to a grisly crime. Throughout, Dr. Tristan Ingalls dissects the psychological, familial, and societal factors that fueled these acts of violence. The aim is not just to recount shocking events, but to understand what drove them and how the aftermath tore at surviving loved ones.
Key Discussion Points & Insights
I. Thanksgiving: From Gratitude to Grievance
- The hosts note Thanksgiving as a time of togetherness and gratitude, but also a stress point where suppressed resentments can erupt (01:17).
“But in some cases that family time isn’t all gratitude and gravy and instead pent up resentments and long held wishes bring out people's ugliest and deadliest urges.”
—Carter Roy, 01:17
II. Case 1: The Paul Merhige Family Massacre
Background and Family Dynamics
- Paul Merhige was a gifted, high-achieving student whose life unraveled in young adulthood (06:09).
- Exhibited signs of obsessive-compulsive disorder (OCD), severe depression, and social withdrawal, amplified by family crises such as his father’s cancer (07:03–09:27).
- Early perfectionism and need for approval masked deeper psychological issues (08:12–09:03).
Mental Health Analysis
- Dr. Ingalls explains OCD onset, stress-related intensification, and the difference between compulsive behaviors and psychosis (07:59–09:27; 13:56–15:32).
“…high achievement can also sometimes mask deep psychological strain. And with OCD, stress amplifies symptoms… For someone with obsessive tendencies, that triggers the urge to control whatever they can through rituals, rigid routines, or avoidance.”
—Dr. Tristan Ingalls, 08:24
- Discussion of whether Merhige’s actions resulted from OCD, delusions, or an undiagnosed psychotic disorder (14:02–15:32).
“OCD is driven by fear and doubt. Psychotic paranoia is driven by false certainty.”
—Dr. Tristan Ingalls, 15:17
Escalation to Violence
- Multiple suicide attempts, increasingly severe paranoia, threats to family members, and complete social isolation intensified his breakdown (12:11–16:09).
- In 2009, after years of estrangement, Paul’s parents invite him to Thanksgiving in a well-intentioned attempt to reconcile (16:09–18:52).
The Thanksgiving Massacre
- On Thanksgiving night, Merhige sits in silence, then opens fire on his family, killing four (including his pregnant sister and a six-year-old cousin) and injuring others (18:52–23:10).
- He proclaims:
"I've been waiting 20 years to do this."
—Paul Merhige, 22:29
- Flees the scene; is captured a month later after appearing on “America’s Most Wanted” (25:36).
Aftermath: Grief, Blame, and Family Rupture
- Family members launch lawsuits against each other over who enabled Merhige’s presence, highlighting the aftermath of traumatic grief and the search for meaning after senseless violence (26:57–29:24).
“In the search for meaning, blame can become a coping mechanism. It’s a way to make sense of something that feels senseless, which this truly was.”
—Dr. Tristan Ingalls, 26:57
- Merhige accepts a plea deal and receives multiple life sentences, estranged from all but his father (29:31).
III. Case 2: The Omaima Nelson Murder
Early Trauma and Immigration
- Omaima Nelson, born in Egypt, experienced extreme trauma, including forced female genital mutilation at age six (31:53–33:34).
- Dr. Ingalls contextualizes the psychological impact:
“That single event could have left her with a lifelong struggle to reclaim autonomy over her body and her sense of self.”
—Dr. Tristan Ingalls, 33:22
- Family escapes abuse; Omaima pursues a better life, emigrates to the U.S. via a brief marriage, then seeks financial security through relationships (34:46–35:07).
Patterns of Behavior and Crime in the US
- Omaima drifts through relationships, exhibits a pattern of manipulation, impulsive violence, and criminality, possibly as maladaptive coping from trauma (36:35–39:05).
“For someone with a trauma history like hers, crime can ironically become a form of agency. It’s a way to overcompensate for never feeling controlled by someone again.”
—Dr. Tristan Ingalls, 37:38
Whirlwind Marriage and Alleged Abuse
- Marries Bill Nelson within weeks; claims of his abuse and sexual violence complicate motives (43:07–47:59).
“Judging something based only on what’s visible is a cognitive bias. The reality is, most abuse does happen behind closed doors, and abusers can be very skilled at presenting as charming or respectable in public.”
—Dr. Tristan Ingalls, 44:19
- Dr. Ingalls explores the challenges of reconciling varying accounts of the relationship, the influence of trauma on perception, and legal considerations regarding later claims of abuse (44:19–47:59).
The Murder and Dismemberment
- On Thanksgiving 1991, sex play with Bill spirals into violence: Omaima kills, dismembers, and attempts to dispose of Bill’s body in increasingly desperate and gruesome ways (48:12–50:25).
- Speculation about possible cannibalism, which she denies (49:32).
- Dr. Ingalls notes the oscillation between organized concealment and chaotic dissociation:
“It’s as if she was oscillating between two states. Cognitive control and affective chaos.”
—Dr. Tristan Ingalls, 50:25
- Trauma, panic, and possible dissociative or even psychotic break theorized as catalysts (52:06).
Arrest, Trial, and Legacy
- Omaima asks an ex-boyfriend for help with the coverup; he turns her in. At trial, defense claims psychosis and abuse, prosecution highlights deliberate acts to hide the crime (54:09–57:02).
- Found guilty of second-degree murder; sentenced to 27 years to life (57:02).
- History of violence in prison; denied parole, but is eligible again in 2026 (57:02–57:45).
“Perhaps that family reunion is in Omaima’s future, but for the Nelson family, they’ll never be able to have a family holiday together again.”
—Vanessa Richardson, 57:54
Notable Quotes & Memorable Moments
-
“OCD is driven by fear and doubt. Psychotic paranoia is driven by false certainty.”
—Dr. Tristan Ingalls, 15:17 -
“The very people who need connection the most can become unstable to be close to safely. And this is why early and sustained interventions are so critical.”
—Dr. Tristan Ingalls, 19:32 -
On grief aftermath:
“Blaming another family member can momentarily ease that guilt by restoring some kind of illusion of control.”
—Dr. Tristan Ingalls, 26:57 -
Regarding trauma and violence:
“For some survivors, sex becomes transactional. It’s a way to gain control before power can be gained over them.”
—Dr. Tristan Ingalls, 39:14 -
Of family responsibility and tragedy:
“Their actions or inactions weren’t invitations for violence, no matter how you want to frame it. But the speculation and judgment only fuels defensiveness and deepens the family divide.”
