Sarra Gilbert Full Name
The full legal birth name of this convicted killer is Sarra Elizabeth Gilbert. The name Sarra Elizabeth Gilbert appears across all official court documents, arrest records, and psychiatric reports filed in her case. She has never used any other name or legal alias throughout her life.
Her name is sometimes confused with that of the actress Sara Gilbert or the British scientist Dame Sarah Gilbert. These are completely different people with no connection to the Sarah Gilbert case whatsoever. The Sarra Gilbert wiki and Sarra Gilbert Wikipedia searches often pull up these other women by mistake.
Many people searching for Sarra Gilbert – Wikipedia find no direct biography page for her at all. Her information lives entirely within her mother Mari Gilbert’s Wikipedia entry. This is an important detail to clarify for anyone researching the Sara Gilbert murder case online.
Sarra Gilbert Early Life & Education
Sarra Gilbert was born into one of the most unstable family environments imaginable in Lancaster, Pennsylvania. Her father Floyd Gilbert, battled heroin addiction and suffered from schizophrenia, making a safe home life impossible for the children. The family eventually relocated to upstate New York to escape his destructive behavior and presence.
Life in upstate New York was not much easier for young Sarra Gilbert and her sisters at all. She and her siblings spent significant time moving through the foster care system due to ongoing family instability. She was also sexually abused by one of her mother’s boyfriends during these already difficult years.
By age 12, Sarra had already been diagnosed with bipolar disorder and began cycling through mental health facilities. She dropped out of high school at just 16 and moved in with a 22-year-old boyfriend named Emmanuel Martinez. Her early life left almost no foundation for stability or healing in her adult years.
Sarra Gilbert Family
The Gilbert family story is one of the most publicly documented cases of generational trauma in recent American true crime history. Poverty, addiction, abuse, and mental illness ran deeply through every branch of this broken family tree. The Mari and Sarra Gilbert relationship was complicated, painful, and ultimately ended in the most violent way possible.
The family gained national attention after the disappearance of the oldest sister, Shannan Gilbert, in May 2010. That disappearance led police to discover the remains of multiple victims connected to the Gilgo Beach serial killer. From that moment forward, the Gilbert family lived permanently in the spotlight of tragedy and public scrutiny.
Sarra gilbert long island is a phrase often associated with the family because of Shannan’s disappearance on Long Island. However, Sarra herself lived in Ellenville, New York, in the Hudson Valley region of the state. The entire family was shaped and forever changed by what happened on that Long Island night in 2010.
Sarra Gilbert Parents
Sarra Gilbert was raised by her mother Mari after her father, Floyd Gilbert, abandoned the family due to his severe addiction. Mari Gilbert worked multiple jobs including retail management, teaching assistance, and Walmart employment to keep the family alive. She was a strong woman who later became a nationally recognized activist for murder victims’ families.
Floyd Gilbert suffered from both heroin addiction and schizophrenia, two conditions that made parenting completely impossible for him. Sarra gilbert father is widely seen as one of the earliest contributors to the family’s generational mental health struggles. His absence left Mari to carry an impossible weight completely alone for many years.
Sarra Gilbert Parents Table:
| Parent | Details |
| Mother | Mari Gilbert (September 14, 1964 – July 23, 2016) |
| Mother’s Role | Activist, advocate for murder victims, single parent |
| Mother’s Death | Murdered by Sarra Gilbert on July 23, 2016 |
| Father | Floyd Gilbert |
| Father’s Issues | Heroin addiction, schizophrenia |
| Father’s Role | Largely absent from children’s upbringing |
Sarra Gilbert Husband
Sarra Gilbert has never been legally married to anyone throughout her entire life. She had several unstable and often abusive relationships during her early adulthood years. The Sarah Gilbert case files contain no record of any legal marriage or formal long-term partnership.
Her most significant relationship was with Emmanuel Martinez, the father of her son Hayden, born in 2009. That relationship became physically abusive, forcing Sarra to seek refuge in a domestic violence shelter for a period of time. Martinez’s relationship with Sarra ended before her mental health fully collapsed in the years that followed.
Sarra’s escalating schizophrenia made maintaining any healthy relationship completely impossible over time. Her increasing delusions, hospitalizations, and erratic behavior pushed people away consistently throughout her adult years. By the time of the Sarah Gilbert murder, she was completely isolated and alone in her apartment.
Sarra Gilbert Son
Sarra Gilbert gave birth to one son named Hayden with Emmanuel Martinez in 2009. Hayden grew up witnessing his mother’s severe mental health crises from a very young age. The Sara Gilbert kids story is deeply sad, as Hayden experienced things no child should ever have to see.
In February 2016, Sarra drowned the family’s puppy in a bathtub directly in front of young Hayden during a psychotic episode. She believed the dog was rapper Eminem and that it intended to cause her serious harm. This horrific event led authorities to remove Hayden from her care and place him with Mari Gilbert temporarily.
After this incident, the state formally awarded temporary custody of Hayden to his grandmother Mari. Hayden was eventually placed into protective custody outside the immediate Gilbert family following his mother’s final arrest. The Sarra Gilbert son grew up separated from both his mother and grandmother due to this family tragedy.

Sarra Gilbert Siblings
Sarra was the third of four daughters born to Floyd Gilbert and Mari Cox Gilbert. Her sisters were Shannan, Sherre, and Stevie, and all four grew up under the same difficult and unstable circumstances together. The Shannan Gilbert sister, Sarra, is the connection that brought this entire family into the national spotlight originally.
Shannan Gilbert was the oldest sister and worked as an escort before her disappearance in May 2010 on Long Island. Her frantic 911 call and subsequent disappearance led police to discover multiple victims buried along Ocean Parkway. Shannan’s remains were found in a nearby marsh in December 2011, and her death was officially ruled accidental despite family protests.
Sherre Gilbert is the second oldest and has continued her mother’s activist work following Mari’s death. She regularly speaks publicly about the Gilgo Beach investigation and the prosecution of suspect Rex Heuermann. Stevie Smith, the youngest sister, has chosen to stay out of the public eye entirely to protect her own wellbeing.

Sarra Gilbert Murder
The Sarra Gilbert murder took place on the morning of Saturday, July 23, 2016, in Ellenville, New York. Mari Gilbert, age 52, was stabbed 227 times by her daughter Sarra inside Sarra’s apartment on Warren Street. This act of violence shocked the entire country and brought massive media attention back to the already tragic Gilbert family.
Sarra had stopped taking her prescribed antipsychotic medication nearly two months before the killing took place.

Why Did Sarra Gilbert Kill Her Mother?
Sarra Gilbert killed her mother because of severe paranoid schizophrenic delusions that had completely taken over her mind. She genuinely believed her mother Mari was a shapeshifting demon practicing black magic against her. The question of why Sarra Gilbert killed her mother has one deeply tragic answer — untreated mental illness destroyed her grip on reality entirely.
Voices inside Sarra’s head were telling her that Mari was dangerous and needed to be eliminated before she caused harm. She had been off her court-ordered antipsychotic medication for nearly two months before the attack occurred. Without that medication, her paranoia escalated to a point where she viewed her own mother as a supernatural threat to her life.
Key Reasons Behind the Killing:
- Sarra suffered from severe paranoid schizophrenia with active hallucinations and delusions at the time
- She believed Mari was an evil supernatural being or “bad God” who needed to be destroyed
- Auditory hallucinations were commanding her to kill her mother to stop perceived evil forces
- She had completely stopped taking her Haldol Decanoate injections nearly two months prior
- She also stated on the witness stand that her intention was clearly to kill her mother that day
- Defense experts said she had no grip on reality, while prosecution experts said she still knew murder was wrong
Sarra Gilbert Crime Scene
When police officers arrived at 9 Warren Street for the welfare check, they discovered a scene of extreme violence inside the apartment. Officers first saw what appeared to be a body on the living room floor through a window before entering the home. The Sarah Gilbert crime scene was described by responding officers as one of the most graphic they had ever encountered professionally.
Inside, Mari Gilbert lay on the floor in a massive pool of blood, riddled with over 200 stab wounds across her entire body. A bent and broken 15-inch kitchen knife and a dented fire extinguisher were found beside the victim. Fire extinguisher foam had been sprayed directly into Mari’s mouth, which Sarra later explained was meant to stop her mother from “rising as a demon.”
Officers found Sarra in the kitchen area of the apartment, completely covered in her mother’s blood. She was remarkably calm and showed absolutely no signs of panic, guilt, or emotional distress whatsoever. Sarra told responding officers “I am under arrest” as soon as they entered, and she was immediately taken into police custody.
Sarra Gilbert Mental Health & Trial
Sarra Gilbert’s mental health history was the central issue debated throughout her entire criminal trial in Ulster County. Defense attorneys argued she was acutely psychotic and legally insane at the moment she attacked her mother that morning. Prosecution attorneys argued that despite her illness, she showed clear planning and awareness that murder was both wrong and illegal.
The trial featured testimony from competing psychiatric experts who disagreed sharply on whether she met the legal threshold for insanity. Her own testimony on the witness stand severely damaged her insanity defense when she stated clearly that she intended to kill her mother. The jury ultimately sided with the prosecution and rejected the insanity defense completely after deliberation.
Key Mental Health and Trial Facts:
- Sarra was diagnosed with bipolar disorder at age 12 and paranoid schizophrenia in 2015
- She had been court-ordered to receive Haldol Decanoate injections, but stopped two months before the murder
- Defense expert Dr. Alexander Bardey testified that she was acutely schizophrenic and did not understand reality
- Prosecution expert Dr. Sandra Antoniak confirmed mental illness, but said she still understood her actions were wrong
- The M-FAST psychological test administered during the trial indicated possible malingering of symptoms
- Sarra testified she intended to kill her mother and called the killing “the right thing to do”
- Jury rejected the insanity defense; Judge Williams sentenced her to 25 years to life on August 4, 2017
- Her appeal was denied by the Appellate Division of the New York Supreme Court on November 4, 2021
