Ian Kochinski is a YouTuber, whose image has been altered and used to create a fake CNN tweet screenshot. The Kharkiv Kid finder is not a real thing.
However, the post itself has been manipulated. The city Kharkiv is misspelled in the post as Karkhiv. Additionally, CNN did not tweet about this report and no other credible media outlet has reported about the Karkhiv Kid finder. Moreover, by conducting a reverse search image, we could trace the photo back to a YouTuber Ian Kochinski, under the name of Vaush. The image details match the screenshot from a video captioned "Tim cast IRL - Charlie Kirk And Vaush Join To Discuss And Debate" in August 2021.
Reuters contacted CNN regarding the post and their reponse said "That is a fabricated post and is not affiliated with CNN in any way." Reuters also reports that there are several claims misrepresenting CNN on social media.
There are no conclusive reports on the Karkhiv Kid finder or any other information related to Ian Kochinski. Thus, we can say the claim is false.
