Last night, 31-year-old Erika Menendez — the woman accused of pushing 46-year-old Indian immigrant Sunando Sen to his death on the tracks of the 40th Street-Lowery Street subway station last week — appeared in Queens district court for an arraignment. The New York Daily News reports that Menendez "broke into a maniacal fit of laughter" and "started cackling" when prosecutors formally charged her with second-degree murder as a hate crime based on her Saturday confession to police that she shoved Sen "because I hate Hindus and Muslims." "Tell your client this is not funny," Judge Gia Morris advised Menendez's attorney. Prosecutors also informed the court that Menendez has shown no remorse for the crime since she was arrested on Saturday, and that she apparently "even bragged about smoking pot and having sex with 'her man in Brooklyn' after the murderous deed." The court has ordered a psychological evaluation of Menendez, whose cousin described her as "bipolar" when contacted by the New York Post.
