Usually, the jihadis want to show off their “victims” in a videotape, either alive or in the process of executing them. This guy was seen on videotape, but has since disappeared. No body was ever found, as in past disappearances, usually tortured and dismembered. They may have “converted” him to islam, and as much as I hate to say it, he may be one of them, now, via Stockholm Syndrome or brainwashing. But, at least he may still be alive................
I recall a video of bad quality showing what might have been Matt being shot. It was a couple of years ago.
