Princeton Man Faces Court as Prosecutors Prepare Indictment for Gruesome Murder of His Brother

A former star athlete from Princeton, New Jersey, accused of murdering his brother and a family cat last month, is set to appear in court today. Matthew Hertgen, 31, gained notoriety in high school as a promising student and athlete, but now finds himself at the center of a tragic and horrific crime.

The charges against him include the brutal killing of his 26-year-old brother, Joseph Hertgen, in their family’s apartment. Prosecutors claim that Matthew used both a knife and a golf club in the attack. Additionally, he faces charges of animal cruelty related to the cat’s death.

Pre-Indictment Hearing Scheduled

Today’s hearing at Mercer County Superior Court is classified as a pre-indictment conference. Legal experts anticipate that the session will be brief, serving primarily as a procedural formality. Earlier this month, Matthew agreed to pretrial detention, which relieved prosecutors of the burden of presenting evidence to justify his continued incarceration prior to trial.

Details of the Incident

The Princeton police responded to a 911 call made by Matthew on February 22, alerting them to a fire and reporting his brother’s lifeless body at the Michelle Mews Apartments complex. During the call, when asked how his brother was injured, Matthew responded with hesitation, stating, “I’m not gonna go into any more details right now,” according to a probable cause statement.

Upon arrival, authorities discovered Matthew at the scene alongside Joseph’s body, which exhibited severe head injuries, including an eye that had been violently removed. The body showed additional trauma to the chest and upper body. Investigators also noted a cup of blood and utensils smeared with blood left out on a plate, indicating the violent nature of the crime.

Investigation Reveals Disturbing Findings

Authorities soon uncovered a deceased cat on an ottoman, which appeared to have been partially burned, further complicating the investigation. While being interviewed, Matthew reportedly expressed that he had experienced a “fit of madness” approximately forty minutes prior to the incident. He had visible cuts on his hands, raising questions about his state of mind.

Impact of Mental Health on Case

Investigators conducted interviews with Matthew’s surviving brother, who detailed Matthew’s ongoing battle with mental health issues for the past five years. He mentioned that he had seen Matthew earlier on the day of the crime when he appeared to be experiencing a depressive episode and “terrifying visions.” Such insights raise critical questions about Matthew’s mental health, potentially influencing the legal proceedings.

The Path to Pretrial Detention

Matthew’s appearance in court on March 6 was focused on a detention hearing. Typically, these hearings involve the presentation of evidence by both the defense and prosecution to decide whether a defendant should remain in custody or be released on bail. However, Matthew’s pretrial detention agreement negated the need for evidence to be presented during that session.

Public Reaction and Expert Insight

Legal professionals, such as David Gelman—former prosecutor and current CEO of Gelman Law—expressed shock at the gruesome nature of the murder. He noted, “It’s very disturbing. You don’t see many murders like this. You can see it’s very personal.” Gelman, who has extensive experience with homicide cases, suggested that given the circumstances, a mental illness defense would likely be considered.

The broader implications of this case are considerable, as it combines elements of familial tragedy and potential mental health crises. Legal experts speculate that seeking a mental health evaluation for Matthew will become an important part of the defense strategy as proceedings unfold.

Identities and Athletic Legacy

The Hertgen brothers were both prominent soccer players during their high school years at Toms River High School, with Matthew furthering his academic career at Wesleyan University and Joseph playing at the University of Michigan. Their shared history as athletes adds another layer of complexity to this already heartbreaking situation.

Next Steps in Legal Proceedings

While Matthew is scheduled to return to court on March 24, there is considerable uncertainty surrounding his legal fate. The public defender’s office, representing Matthew, has declined to comment on ongoing proceedings. The prosecution, however, is preparing to deepen its investigation, with a focus on the underlying mental health issues that may have influenced Matthew’s actions.

As information continues to emerge regarding this unsettling case, the community grapples with the shocking reality of a tragic family event turned lethal. The outcome of the legal proceedings will likely stem from a careful examination of evidence and an exploration of Matthew Hertgen’s mental health.

A Narrative of Tragedy

This case reflects not only the shocking transformation of a promising athlete into a defendant facing severe charges but also the disturbing intersections of mental health and family dynamics. The tragic circumstances surrounding the Hertgens serve as a grim reminder of the complexities involved in cases of violence and the impact of mental illness on individual behavior. As the legal process unfolds, it will bring difficult questions of responsibility and mental health to the forefront of public discourse.
