A former Boston College student pleaded not guilty on Friday to charges of involuntary manslaughter stemming from what prosecutors said was her role in encouraging her boyfriend to commit suicide. A lawyer for Inyoung You, 21, entered the plea on her behalf during a hearing in Suffolk County Superior Court after she returned from South Korea to face charges brought last month over the May 20 suicide of her college boyfriend, who leaped to his death from a parking garage hours before his graduation. “These text messages demonstrate the power dynamic of the relationship,” Assistant District Attorney Caitlin Grasso said in court.
