Police didn’t buy the story about the Black men and had doubts that the bomb was even real. Wells himself didn’t seem very concerned it would go off, leading investigators to believe he was a willing participant in the botched heist. When the explosive device detonated, the bomb squad was still a few blocks away. Police later followed the instructions for the scavenger hunt and determined there was no way Wells would have completed it in time to remove the collar bomb and save his life. They believe that the note and scavenger hunt were written and designed by Rothstein (the man who later reported the body in the freezer to police).
