...In the meantime, the real killers find the gun at the restaurant, run to Blake's car, murder Bakley, run back to the restaurant and return the gun to where they had found it and where now Blake retrieves it. More details to come as the script develops.

It is odd, though, that Blake failed to notice that the gun was a bit warm...

The Real Killers obviously used a different route between the restaurant and Blake's car, otherwise they would've passed Blake twice!

The viewer may also axe, how could the Real Killers pass Blake twice on the way to and from the restaurant? The answer is amazingly simple and O.J.
