A judge has dismissed the indictment against the NYPD officer who shot and killed an unarmed teen in his Bronx home last year. The dismissal was for a technicality, as the Bronx DA’s office erroneously instructed members of the grand jury that they did not have to consider if Officer Richard Haste’s colleagues informed him that 18-year-old Ramarley Graham was armed.

“With no great pleasure, I am obliged in this case to dismiss the charges,” Supreme Court Justice Steven Barrett said as he made his decision, according to DNAinfo.

Graham’s mother Constance Malcolm had to be removed from the courtroom after the judge announced his decision. Video from NY1 shows Malcolm screaming, “He killed my child! What more can you do to me?”
