I don't see that happening. The POI is large, but he's obese, not a body building physique. Having had to assist in removing remains from an accident scene I can assure you that lifting a "dead weight" (and I mean no disrepsect - that is the term used) body, who is unconscious or not breathing is EXTREMELY difficult, harder than you'd think. A single person normally can't do so. Lifting that same person up and over your head to move them over a railing would require upper body strength I don't see the perp having. He looks really out of shape to me, despite his pounds. I think the bridge was likely a "red herring".
