THE BRONX - A Parkchester woman accused of killing her two young children pleaded not guilty at her arraignment earlier today. Lisette Bamenga, 29, is accused of poisoning her son and daughter by spiking their drinks with windshield wiper fluid, and then drowning them in the bathtub. Investigators say Bamenga then allegedly tried to commit suicide by cutting her wrists and turning on the gas in her apartment. Bamenga's lawyer has consistently blamed his client's husband, Trevor Noel, claiming Noel drove his wife to insanity though affairs and other children born out of wedlock. The judge also ruled that Bamenga was unfit to attend her children's funeral this Saturday. Bamenga is due back in court on Dec. 4. Bronx mother charged with murder of 2 children
