Homicide Prosecutor Reveals A Surprising Childhood Pattern In Serial Killers! With Matt Murphy

Summary of the video’s main points

The episode features homicide prosecutor Matt Murphy, who argues that many popular beliefs about crime—especially serial killing and violent homicide—are built on myths or overly simplistic psychology. As a prosecutor (author of The Murder Book and former senior deputy district attorney in Orange County, CA), he emphasizes that charging decisions depend on evidence. He also contends that common “motive” frameworks often miss what actually matters: the offender’s actions, intentions, and willingness to harm.

1) How homicide charges differ (murder vs. manslaughter)

Murphy explains legal distinctions using California jury-instruction concepts:

• Murder: intentional killings without planning/forethought. He notes many cases fall here, often involving anger or domestic conflict.
• Involuntary manslaughter: can involve “passion” under circumstances where a reasonable person might be emotionally moved—yet it still excludes true self-defense.

He illustrates with an example such as an abuser who assaults a child, where the caregiver’s response (killing the abuser) may be framed as mitigating but is not legally justified.

2) Prosecutor ethics: when charges should be filed

Murphy describes a two-part ethical filter:

• Subjective certainty: the prosecutor must believe the suspect is the person who committed the crime.
• Objective likelihood: there must be enough evidence for a jury to find guilt beyond a reasonable doubt.

He also notes prosecutors often refuse or don’t file cases that never become public.

3) Rejecting “empathy-deficit” as the defining trait of serial killers

Murphy criticizes the common checklist that defines psychopaths/serial killers mainly by a lack of empathy. He argues:

• Serial killers can often understand others’ emotions.
• What’s “missing” is not necessarily emotional awareness, but sexualized sadism, narcissism, and a willingness to exploit and harm.
• He suggests the term “evil” better captures what he sees in serial-killer behavior—cruelty and predatory intent rather than “mental illness.”

4) “Child abuse creates serial killers” is a myth (“vampire bite” metaphor)

A central theme is pushing back against the idea that childhood abuse directly causes serial killing or child molestation.

• Murphy says most abused children do not become serial killers.
• He argues people prefer a cause-and-effect story that feels preventable—“avoid the bite; prevent the monster”—but serial killers are often “spoiled and privileged” rather than abused.
• He references examples of high-profile offenders whom he claims were not abused, contrasting them with the broader reality that correlation ≠ causation.

He also adds a moral critique: emphasizing abuse as a “cause” can create stigma for survivors who became good adults and can treat victimhood like a “scarlet letter.”

5) Sexual motivation and “sadistic lust murders”

Murphy says serial killings often involve sexual assault or sexual sadism. He also argues that “serial killer” is a broad label that mixes different offender types:

• Some serial murder reflects sexual predation. He cites authorities and notes FBI studies indicate a majority of studied cases involve sexual assault (and he suggests it may be even higher).
• He distinguishes this from other multiple-murder categories, such as gang-related killings, killings for money, or “mercy killers.”

6) Case anecdotes used to illustrate “evil,” manipulation, and courtroom dynamics

Murphy uses several investigation/defendant narratives to support his broader claims:

• Rex Heuermann (Gilgo Beach): he discusses alleged sexual components and references evidence such as pornography linked to investigative theories.
• Trial/strategy dynamics: he describes how certain defendants “defend themselves,” including denial or self-serving courtroom storytelling.
• Skyler DeLeo / Hawk family case: he describes “transactional immunity” offered to a wife (she refused) and argues the evidence showed she was deeply involved—asserting she used her child to lure victims. He frames her as “evil” and says she received life sentences without parole eligibility.
• He also criticizes mitigation arguments he believes are inappropriate—particularly when a defendant’s family seeks sympathy with stories Murphy thinks contradict the nature of the crime.

7) Carmelo Anthony case: strong legal-moral condemnation

Murphy turns to a high-profile homicide case involving Carmelo Anthony, which he says he strongly believed was wrong but had not previously discussed publicly.

His position:

• Race is irrelevant to the legal question. A stabbing in response to a push/ego conflict does not qualify as lawful deadly-force self-defense.
• He argues the defense position is legally and morally wrong, characterizing it as “protecting ego,” not protecting life.
• Even if circumstances provoke fear or anger, the law does not permit deadly force for something like a shove.
• He discusses sentencing possibilities: while outcomes can vary by jurisdiction, he believes Anthony would still face prosecution as murder (he mentions second-degree murder in a California context). He estimates a parole hearing might occur after many years if remorse and programming are shown.

Overall, Murphy argues that these cases should be judged by evidence and legal standards—not by comforting psychological myths.
