In a grim discovery on a Sunday evening in January 2016, the decomposing bodies of 38-year-old Rosie Sanchez and her 40-year-old boyfriend, Anderson Nunez, were found inside their Sheepshead Bay, Brooklyn apartment. The couple had been brutally murdered days earlier, on December 28, 2015, in what would unfold as a chilling tale of familial betrayal.
An investigation quickly pointed to two suspects: Rosie's own 15-year-old daughter and her daughter's older boyfriend.
The scene within the fifth-floor apartment on Batchelder Street was one of extreme violence. Rosie Sanchez was found with a gunshot wound to her head and a stab wound to her heart. Anderson Nunez had been shot twice and stabbed more than 30 times. For days, their bodies lay undiscovered while the teenage daughter reportedly went about her life, even allegedly partying in Times Square on New Year's Eve. The grim discovery was only made after the teen confided in a cousin, who then alerted the police.
Within days, Rosie Sanchez's daughter was arrested and charged as an adult with two counts of second-degree murder and weapons possession. Her 28-year-old boyfriend, Jerry Maisonett, was arrested about a month later. Investigators believed he supplied the gun used in the killings and was the one who shot Nunez. Court documents alleged that Maisonett even returned to the apartment with the daughter to search for the murder weapons and stabbed Nunez again to 'make sure he was dead.' The motive for the brutal slayings was initially clouded by the daughter's conflicting stories, which included claims of sexual and physical abuse.
The legal process brought the disturbing details of the crime to light. In 2022, Jerry Maisonett pleaded guilty to first-degree murder and was subsequently sentenced to 22 years to life in prison. Rosie Sanchez's daughter was convicted by a jury of two counts of first-degree manslaughter and one count of criminal possession of a weapon. In August 2023, she was awaiting her sentencing, bringing a close to a case that began with a daughter's chilling betrayal and ended with the violent deaths of her mother and her mother's partner.
