sean boyle - this crook insulted spider-man by wearing a mask resembling his while committing crimes; he came to be known as the "spider-mugger". boyle steals several wallets, including peter parker's and, accidentally, one of his spider-man webshooters. he attempts to sell the device to his fence, dooley, at the blind spot (a waterfront bar for crooks), but dooley considers the webshooter useless and returns it. when boyle puts it on only to discover what it actually is, he accidentally shoots a spider-tracer onto the back of bruno karnelli, who is also at the bar. boyle hides this from dooley and starts using the webshooter to restrain his victims, until he realises that he must have stolen it from the real spider-man and one of the wallets he's given to dooley contains his id. he returns to the blind spot and asks for it to be returned, attacking dooley with webbing, but dooley turns it around on him and starts strangling boyle with it. later on, as dooley drives off, spider-man finds boyle's lifeless body with the webshooter and tracer still on him. gonzales and o'neil witness spider-man doing this and assume he has murdered boyle.
