There's no proof for it but a statement from a neighbor will leave one thinking it's possible.
Very strange that immediately following a raid by the FBI the morning of April 29th the journalist is never seen again.
Here's the statement:
His last post on social media, responding to a tweet talking about U.S. monitoring of Russian troop tactics, was posted on Twitter at 4:59 a.m. on April 27. His neighbor and eyewitness to the raid said that he saw the unmarked police vehicles "just before dawn," meaning his last post was just moments before the raid and his disappearance.
