He is not the older brother.
Also at 1:13 into 1:23 of this video, too.
No, that is not the video I saw. And the picture of the man on the ground is not what I saw either. Thanks for trying to find the link. I’ve looked for the report and video with no results. I admit I’m not very good at searching for these. I saw the report around 5am central the morning the older brother was captured. It was Griff Jenkins of Fox News reporting live from the scene of capture and also showing the video he had gotten just shortly before.
