The link you posted claims Crooks bought a 5 ft ladder.
In the posted pics, that’s not a 5 ft ladder.
Also, how could one transport the ladder in the picture in the car that was linked to Crooks?
Not asking you for the answers but these are questions that immediately pop up in my head.
Pretty sure the ladder in the photo was placed there after the incident to give police access to the roof.
