That dude is way younger than the POI, would have been arrested on the spot for his involvement w/ the Sage disappearance if they found him in the apartment today. It would seem it is not the right person, just another guy with dreads.
But we don't know the age. The witness said 32. That is his guess. Also, looking at freeze frame images of the DG, I don't think he looks particularly overweight. 250lbs is pretty heavy.
