Officer Veckash Khedna, the brother of slain NYPD hero Jonathan Diller, broke down during testimony in Guy Rivera's murder trial in a Queens courtroom as he delivered heart-wrenching testimony against the accused cop killer who allegedly gunned down the NYPD hero. Khedana testified about the March 2024, traffic stop in Far Rockaway where Rivera was allegedly caught with an illegal gun in his pocket and allegedly pointed it at the chest of a police sergeant, Sasha Rosen. He testified that he made a split-second decision to shoot Rivera as Diller lay mortally wounded and died. The emotional testimony came as Rivera's widow Stephanie Diller watched haunting images of her husband's last moments being shown to the jury. If found guilty, Rivera faces life without parole.
