"The roller coaster we are on is relentless, many dead ends. We are hoping he is just off the grid doing a complete reset for himself and doesn’t have any idea what is happening," Mark wrote. "The area we suspect he traveled, if that’s what’s happening, is very remote, which adds to our concern. I am sending this out to try comforting everyone who is worried, I can honestly say that in my life I have never felt more supported. Thank you, I intend my next message to be a group photo of my family reunited. Thank you, one and all."
Authorities are asking anyone with information about Grant's whereabouts to contact 911 or RIT Public Safety at 585-475-3333.
