Decoy(s)

Did the shooter employ decoys to confuse authorities about his identity and getaway route?

The man on the ebike that entered Central Park at 6:45 a.m., was he a decoy who had a two-minute head start? There were three independent cameras from different angles whose timestamps showed this individual showing up at the intersection at 6:44 right before entering Central Park. Did he get on the e-bike right when the shooter was informed by phone that BT was about to walk in front of him?

Did the shooter actually just stay in the vicinity of the shooting, while the authorities were led to think he had escaped northward?

Is Luigi Mangione himself just a decoy? Did Luigi just stay up north during the shooting and never went south past Central Park at all that morning?
