He told journalists this, according to Fox News.When asked if he had seen the video of the killing and if he could comment on it, the American president asked when and where exactly the incident had taken place.“Horrible. No, I hadn’t heard [about it],” Trump admitted, but promised he “will know all” about the murder by tomorrow morning.Zarutska was killed in the subway of Charlotte, North Carolina, on August 22. She was a refugee who had fled to the U.S. to escape Russia's war against Ukraine.The suspect was immediately arrested — 34-year-old DeCarlos Brown Jr., who had previous arrests for grand theft, armed robbery, and making threats. He had also served time for illegal possession of a deadly weapon.Police said it is currently unclear what motivated the attack on the Ukrainian woman. Later, a video of the killing surfaced online, showing that when Zarutska entered the subway car, she sat in front of the suspect. After some time, he pulled out a knife and attacked her, then left the scene carrying the bloodied weapon.
