LONDON (AP) — The crime was in London, the suspect was Russian and the witness who saw the beating on a video call was in the United States and happened to be the youngest son of U.S. President Donald Trump. Barron Trump called police in the British capital and his intervention more than a year ago led Wednesday to the assault conviction of Matvei Rumiantsev, who admitted he was jealous of his girlfriend's friendship with Trump. Trump said he placed a late night FaceTime call to the victim, a woman he met on social media, and was startled when it was answered by a bare-chested man.
