Jury Finds Elmsford Woman Menaced Ex-Girlfriend's Family With Purple Ghost Gun After Barging Into Their Home

ELMSFORD, NY — A jury has returned a guilty verdict in a fraught case in Westchester County.

Westchester County District Attorney Susan Cacace announced that 36-year-old Brooke Manderson, of Elmsford, was convicted by a jury on Wednesday on all counts presented at trial for menacing the family of her ex-girlfriend with a loaded gun and barging into the family's apartment.

She was convicted of three felony counts of first-degree burglary; three felony counts of second-degree criminal possession of a weapon; one felony count of third-degre criminal possession of a weapon; two misdemeanor counts of second-degree menacing; and one misdemeanor count of third-degree menacing.

Manderson is scheduled to be sentenced on June 30, when she faces up to 25 years in prison on the top burglary charge. She has been remanded to the Westchester County Jail until her sentencing date.

"The defendant subjected her former girlfriend and the woman's family to an unrelenting campaign of harassment, showing up at their door, menacing them with a loaded gun and demanding to see her former partner," DA Cacace said. "Thanks to the jury's 10-count guilty verdict, this campaign has met its end. I am grateful to the victims in this case for working with our office to hold the defendant accountable, and for the police and prosecutorial team who ensured she would be brought to justice."

"Domestic abusers have no safe harbor in Westchester County, and my office will vigorously prosecute all instances of domestic violence within our purview," the DA added. "I encourage anyone experiencing abuse or seeking flight from an abusive relationship to contact our Special Prosecutions Division at (914) 995-3000. Our team is on hand to help you find the road to safety."

On Dec. 28, 2024, Manderson went to the apartment of her former girlfriend's family, in Port Chester, demanding to see her former girlfriend. Manderson entered the building and began banging on their apartment door. After a family member answered the door, Manderson tried to shove the door open and pulled out a gun, pointing it in the family member's direction and then at her former girlfriend, who was standing on the other side of the door.

Manderson then barged her way into the apartment and, once inside, continued to threaten members of the family and menace them with the gun.

Once Port Chester police arrived outside the building, Manderson discarded the loaded 9mm Luger semi-automatic pistol in the living room, and was soon taken into custody.

The case was investigated by the Port Chester Police Department with assistance from the Westchester County District Attorney's Office and the New York State Police. The case is being prosecuted by Domestic Violence Deputy Bureau Chief Janelle Armentano and Assistant DA Jessica Soares.
