LE has key video, clearly shows someones face. Places someone at the scene, holding device, wheeling it. Not public, still very sensitive. 8:02
They see this person wheeling something on 27 th Street, they see him leave the pressure cooker package, then two others probably scavenge the duffel, leave the plastic garbage bag with the device behind. This man stood out to LE because he appeared on video near the 23rd device. 8:01 ish CNN being very cautious thorough reporters on this beat attest to info based on LE sources, Shimon Prokupecz
LE is on it basically.
Why here? Why now?
Not yet time for crowd sourcing. LE may know more they want to check out first, FBI expert
