Mari Gilbert (June 22, 1964 – July 23, 2016)[1] was an American activist and murder victim advocate.


Gilbert was an advocate for her daughter, Shannan, a 24-year-old woman from New Jersey who disappeared in May of 2010; the investigation of Shannan's disappearance led to the discovery of ten homicide victims scattered along Ocean Parkway in New York.[2] Investigators believed that Shannan died of an accidental drowning that was unrelated to the crimes of the Long Island serial killer, but Gilbert challenged the finding and fought to have the case reopened as a murder investigation. An independent autopsy sought by Gilbert’s family found that Shannan may have been strangled to death. [3] Gilbert and her other daughters (Sarra, Sherre) frequently appeared on television shows discussing the case.[citation needed]


Gilbert was stabbed to death by one of her daughters, Sarra, in Sarra's apartment building on Warren Street in Ellenville, New York on July 23, 2016.[4] Sarra suffered from schizophrenia. One report claimed that Sarra "had voices in her head telling her to carry out the crime".[5][6] Sarra was charged with second-degree murder and fourth-degree possession of a weapon,[7] convicted of murder, and sentenced to 25 years in jail in August 2017.[8]
